1) The 3 kg brick has more mass, so it will have more kinetic energy.

2) Gravity does not do more work on one brick compared to the other.

1) The 3 kg brick has more kinetic energy than the 2 kg brick when it hits the bottom of the bridge because kinetic energy is directly proportional to mass. The formula for kinetic energy is KE=1/2mv², where m is the mass of the object and v is its velocity. Since both bricks are dropped from the same height and experience the same acceleration due to gravity, they will have the same velocity when they hit the bottom. However, the 3 kg brick has more mass, so it will have more kinetic energy.

2) Gravity does the same amount of work on both bricks because they both fall the same distance and experience the same force of gravity. Work is defined as force times distance, so in this case, the force of gravity is the same for both bricks and the distance they fall is also the same. Therefore, gravity does not do more work on one brick compared to the other.

EXPLANATION

Magnification is a measure of an image's size compared to the size of the object that formed the image.

Since magnification is a ratio that is proportional to the sizes of the image and object, it follows that if magnification is less than 1, the image is smaller than the object, if magnification is equal to 1, the image and object are the same size and if magnification is greater than 1, the image is larger than the object.

Therefore, it is False.

(a) The position of the particle when velocity is zero is - 27 m.

(b) The dimensions of a, b, c, and d are LT⁻³, LT⁻², LT⁻¹ and L respectively.

The velocity of the particle is change in position of the particle with time.

v = dx/dt

v = 6t - 18

when velocity = 0

0 = 6t - 18

6t = 18

t = 18/6

t = 3 seconds

x = 3(3²) - 18(3)

x = -27 m

x = at³ + bt²  + ct + d

if t is in seconds and x is meters, the dimensions of a, b, c, and d is calculated as;

x(m) = at³(m/s³) + bt²(m/s²) + ct(m/s) + d(m)

Thus, the dimensions of a, b, c, and d are LT⁻³, LT⁻², LT⁻¹ and L respectively.

Answer:

1250 J

Explanation:

Work is said to be done when a force causes an object to move over a distance. The amount of work done (W) is calculated by multiplying the force by the distance traveled.

That is;

W = F × d

Where;

W = work done (J or N/m)

F = force (N)

d = distance (m)

Based on the information provided in this question, F = 5000N, d = 0.25m

Hence;

W = F × d

W = 5000 × 0.25

W = 1250J

Therefore, 1250Joules of work is done by the jack.

Answer:

Explanation:

The image is formed at a distance of 7.5 cm from the convex lens and the magnification of the image is 0.5, meaning it is half the size of the object.

To analyze the given scenario, we can apply the lens formula and magnification formula. Here are the calculations:

Lens formula:

The lens formula relates the object distance (u), image distance (v), and focal length (f) of a lens:

1/f = 1/v - 1/u

Given:

focal length (f) = 5.0 cm

object distance (u) = -15.0 cm (negative sign indicates that the object is located on the same side as the incident light)

Plugging in the values:

1/5 = 1/v - 1/(-15)

Simplifying:

1/5 = 1/v + 1/15

Combining the fractions:

1/5 = (15 + v) / (15v)

Cross-multiplying:

15v = 5(15 + v)

Expanding:

15v = 75 + 5v

Simplifying further:

10v = 75

Dividing both sides by 10:

v = 7.5 cm

Therefore, the image is formed at a distance of 7.5 cm from the lens.

Magnification formula:

The magnification (M) relates the height of the image (h') to the height of the object (h):

M = -v/u

Given:

object height (h) = 3.0 cm

Plugging in the values:

M = -7.5 / -15

Simplifying:

M = 0.5

The magnification is calculated to be 0.5, which indicates that the image formed by the lens is half the size of the object.

(a) The impulse reaction of the gadget is h(n) = δ(n+1) + δ(n-1). (b) The system is causal due to the fact the output simplest relies upon present and beyond inputs, x(n+1) and x(n-1), respectively. (c) The system is linear because it satisfies the homes of superposition and homogeneity.

(d) This is an IIR (Infinite Impulse Response) filter out because the output relies upon beyond inputs. (e) The frequency response of the machine is H(z) = \(z^(-1) + z\). (f) The device is BIBO strong considering its miles are linear and causal, and its impulse response is finite, ensuring bounded output for bounded enter.

(a) To discover the impulse reaction of the gadget, we want to enter an impulse signal. An impulse signal is represented as δ(n), that is 1 at n = 0 and 0 for all different values of n.

Let's alternative δ(n) into the given equation:

y(n) = x(n+1) + x(n-1)

For n = 0:

y(0) = x(1) + x(-1)

For n = 1:

y(1) = x(2) + x(0)

For n = -1:

y(-1) = x(0) + x(-2)

For n ≠ 0, 1, -1, y(n) = 0 considering the fact that x(n) = 0.

So, the impulse reaction of the gadget is:

h(n) = δ(n+1) + δ(n-1)

(b) The machine is causal if the output y(n) relies upon only on the present and beyond inputs x(n), x(n-1), x(n-2), and so forth. In this case, due to the fact that y(n) simplest depends on x(n+1) and x(n-1), it does not depend on future inputs. Therefore, the machine is causal.

(c) The system is linear if it satisfies the properties of superposition and homogeneity. Let's confirm these houses:

Superposition:

For two inputs \(x1(n)\)and \(x2(n)\) their corresponding outputs \(y1(n)\) , \(y2(n)\), we've got:

\(y1(n) = x1(n+1) + x1(n-1)\)

\(y2(n) = x2(n+1) + x2(n-1)\)

Now, allow's apply the machine to the linear aggregate of inputs:

\(y(n) = ax1(n) + bx2(n)\)

=\(a(x1(n+1) + x1(n-1)) + b(x2(n+1) + x2(n-1))\)

= \(ax1(n+1) + ax1(n-1) + bx2(n+1) + bx2(n-1)\)

This fits the output received when the system is carried out to the linear mixture of the person inputs. Therefore, the device is linear.

(d) This is an IIR (Infinite Impulse Response) clear out due to the fact the output depends on each contemporary and past input, as visible inside the equation y(n) = x(n+1) + x(n-1).

(e) To locate the frequency response, we will take the Z-remodel of the gadget's impulse response. Applying the Z-transform to the impulse response h(n) = δ(n+1) + δ(n-1), we get:

H(z) =\(Zh(n) = z^(-1) + z\)

The frequency response of the device is the Z-transform of the impulse reaction.

(f) BIBO (Bounded-Input Bounded-Output) stability refers to the belongings of the device to produce bounded output for any bounded input. In this example, because the system is linear and causal, and the impulse reaction is finite, the device is BIBO stable.

Digital filters are important in digital signal processing. FIR and IIR filters are two types of digital filters. The main difference between FIR and IIR filters is that FIR filters are known as non-recursive filters, while IIR filters are recursive filters. In this answer, we will explore more about the differences between FIR and IIR filters.

FIR Filters FIR stands for finite impulse response. FIR filters are also called non-recursive filters. In an FIR filter, the output depends only on the current input and the previous inputs. FIR filters are also known as moving average filters. FIR filters have a linear phase response, which makes them useful in audio and image processing. FIR filters have more stable responses compared to IIR filters, which means they are more predictable.

IIR filters are more efficient than FIR filters because they use feedback loops. IIR filters have nonlinear phase responses, which make them useful in signal processing and control systems. IIR filters are less stable than FIR filters, which means they are less predictable.

When an aircraft is flying at a high AOA (angle of attack), the downward-moving blade of the propeller has a higher resultant velocity than the upward-moving blade, resulting in more lift.This is known as a P-factor. The result of this is the airplane yawing to the left.

This happens because the ascending blade of the propeller produces less thrust than the descending blade, causing the plane to veer left.Let us first define what AOA is.AOA (angle of attack) is the angle between the relative wind and the chord line of the wing. In other words, it's the angle between the wing's direction of motion and the wing's relative wind.A propeller blade is made up of two parts: an ascending blade and a descending blade. Because the ascending blade is moving slower through the air than the descending blade, it produces less lift. This causes the airplane to yaw to the left, as mentioned previously.

The average rate of a reaction is equal to its instantaneous rate at a given second when the reaction is happening at a constant rate. This occurs when the concentration of reactants is constant, and there is no change in the reaction mechanism or conditions.

The average rate of a reaction is calculated by dividing the change in the concentration of the reactants by the time taken for that change to occur. On the other hand, the instantaneous rate of a reaction is the rate at which the reaction is occurring at a particular point in time.

When the reaction is happening at a constant rate, the average rate and the instantaneous rate are the same at any given second. This means that the rate of the reaction does not change over time, and the concentration of the reactants is constant. However, in most cases, the reaction rate changes over time, and the instantaneous rate at any given second is not equal to the average rate.

In conclusion, the average rate of a reaction is equal to its instantaneous rate at a given second when the reaction is happening at a constant rate.

Answer:

current must flow and chemical energy must take place

The Moon creates tides on Earth by exerting a gravitational pull on the oceans.

The gravitational pull of the Moon is stronger on the side of the Earth closest to it, creating a bulge in the ocean and resulting in a high tide. On the side of the Earth furthest from the Moon, the gravitational pull is weaker and causes the ocean to be pulled away from the shore, resulting in a low tide.

We have two high and two low tides each day because of the Moon's orbital period, which is approximately 24 hours and 50 minutes. The tides vary with the phase of the Moon, as the Moon is closest to the Earth during the Full Moon and furthest away during the New Moon.

During the Full Moon, the gravitational pull is greater, resulting in higher and lower tides. During the New Moon, the gravitational pull is weaker, resulting in smaller tides.

Answer:

E_total = 3 N / A

Explanation:

The electric field is a vector magnitude so when adding we must use vectors, in this case as the initial field E = 4N / c goes towards the axis axis and the field created by the fixed charge (E1) is also on the axis x we can add in scalar form.

               E_total = E + E₁

the expression for the field of a point charge is

                E₁ = k q₁ / r²

for the point x = 2m, they do not say that the total field is zero, so the charge q1 must be negative

                 E_total = E -k q₁ / r₂

we substitute

                   0 = E - k q₁ / r²

                   q₁ = \(\frac{E r^2}{k}\)

let's calculate

                   q₁ = \(\frac{4 \ 2^2}{9 \ 10^{-9}}\)

                   q₁ = 1.78 10⁻⁹ C

now we can calculate the field for position x = 4 m

                   E_total = 4 - 9 10⁹  1.78 10⁻⁹ / 4²2

                   E_total = 3 N / A

The distance between 1.00 and 0.80 markings on the stem will be 0.45 m.

To solve this problem, we need to use the principle of flotation,

"When a hydrometer is placed in a fluid, it floats at a level where the weight of the hydrometer is equal to the weight of the fluid displaced by the hydrometer."

The distance between the 1.00 and 0.80 markings on the stem corresponds to the volume of fluid displaced by the hydrometer.

Let's assume that the hydrometer floats in water, which has a density of 1000 kg/m³.

Given, weight of the hydrometer = 0.125 N,

So, the volume of water displaced by the hydrometer is:

Volume of water = Weight of hydrometer / Density of water

= (0.125 N) / (1000 kg/m³)

= 0.000125 m³

Since the area of cross-section of the hydrometer is 10⁻⁴ m², the height of water displaced by the hydrometer is:

Height of water = Volume of water / Area of cross-section

= 0.000125 m³ / 10⁻⁴ m²

= 1.25 m

Therefore, the distance between the 1.00 and 0.80 markings on the stem corresponds to a height of 1.25 m - 0.80 m = 0.45 m.
