Determine if the following statement is true or false. The right-hand rule states that you should always hold a compass in your right hand.

Two small balls, each of 1-lb weight, hang from strings of length L=3 ft. The left ball is released from rest with θ=35∘. The coefficient of restitution of the impact is e = 0. 76, the maximum angle through which the right ball swings is approximately 18.4 degrees.

When the left ball is released, it swings down and collides with the right ball. The two balls then swing together as a single system. Due to the law of conservation of momentum, the momentum of the system is conserved during the collision. However, energy is lost due to the coefficient of restitution.

We can use conservation of energy to find the maximum height the left ball reaches at the moment of impact. The initial potential energy of the left ball is given by mgh, where m is the mass of the ball, g is the acceleration due to gravity, and h is the height of the ball above its rest position. At the moment of impact, all of the potential energy of the left ball is converted into kinetic energy, which is then transferred to the right ball during the collision. Therefore, we can equate the potential energy of the left ball to the kinetic energy of the right ball just after the collision

mgh = (1/2)m\(v^{2}\)

Where m is the mass of the right ball, v is its velocity just after the collision, and h is the maximum height reached by the left ball. Using the fact that the two balls have equal masses, we can solve for v

v = \(\sqrt{2gh}\)

Next, we can use conservation of energy to find the maximum height the right ball reaches. At the highest point of the swing, all of the energy is in the form of potential energy, which is given by mgh, where m is the mass of the ball, g is the acceleration due to gravity, and h is the height of the ball above its rest position. Using the fact that the system loses energy due to the coefficient of restitution, we can write

(1/2)m\(v^{2}\) = emgh

Where e is the coefficient of restitution. Solving for h, we get:

h = (\(v^{2}\)) /(2eg)

Substituting the expression for v derived above, we obtain

h = (2g(L - L*cos(theta)))/(2eg)

Where theta is the initial angle of the left ball, and L is the length of the strings. Finally, we can use the conservation of energy again to find the maximum angle reached by the right ball. At the highest point of the swing, all of the energy is in the form of potential energy, which is given by mgh. Setting this equal to the initial potential energy of the system, we have

mgh = 2mg(L - L*cos(theta))

Solving for the maximum angle, we get

max angle = arccos((2L - h)/(2L))

Substituting the expression for h derived above, we obtain

max angle = arccos(1 - (eLcos(theta))/(gL))

Plugging in the given values, we get

max angle ≈ 18.4 degrees

Therefore, the maximum angle the right ball swings is approximately 18.4 degrees.

Answer:

2 meters

Explanation:

What we know from the problem are:

From the acceleration formula:

\( \displaystyle{ a = \dfrac{v - u}{t}}\)

Substitute in:

\( \displaystyle{ - 0.25 \ \text{m/s}^{2} = \dfrac{ - 1 \ \text{m/s}}{t}} \\ \\ \displaystyle{ - 0.25 \ \text{m/s}^{2} \ \cdot t = - 1 \ \text{m/s}} \\ \\ \displaystyle{ t = \dfrac{ - 1 \ \text{m/s}}{ - 0.25 \ \text{m/s}^{2} }} \\ \\ \displaystyle{ t = 4 \ \text{s}}\)

Now we know that at 4 seconds, the ladybug is at rest. Therefore, from the distance formula:

\( \displaystyle{s = ut + \dfrac{1}{2}a {t}^{2} }\)

Substitute in:

\( \displaystyle{s = (1)(4) + \dfrac{1}{2}( - 0.25) {(4)}^{2} } \\ \\ \displaystyle{s = 4+ \dfrac{1}{2}( - 0.25) (16) } \\ \\ \displaystyle{s = 4 - 0.25 \cdot 8} \\ \\ \displaystyle{s = 4 - 2} \\ \\ \displaystyle{s = 2 \ \text{meters}}\)

Therefore, she will cover distance of 2 meters.

When a comet comes near the Sun, its volatile ice sublimates and changes directly from the solid to the gas phase.

Comets are cosmic snowballs of frozen gases, dust, and rocks, orbiting the Sun. When frozen, comets are the size of a small town. As the comet's orbit approaches the Sun, it heats up, spewing gases and dust onto its giant glowing head, larger than most planets.

Comets vaporize when their orbits come to close to the Sun. Comets do not melt in the strict sense of chinging to liquid. However, since they are made up partly of ice and other volatile compounds, comets vaporize (turn directly to gas) when warmed in the vacuum of space by orbiting near the sun.

The correct answer is option (d). Statement 3 is wrong, and Statements 1 and 2 are correct.

The correct statement among the given options is:

Statement-1:

The damping ratio is a critical parameter in the analysis of any dynamic system. A damping ratio is a dimensionless number that determines the rate at which an oscillatory system decreases in amplitude. It is also known as the damping factor.

When the system is underdamped, the damping ratio is less than 1, and the system is unstable. When the system is overdamped, the damping ratio is greater than 1, and the system responds sluggishly. The system is said to be critically damped when the damping ratio is equal to 1.

The damping ratio is influenced by the values of the passive elements of the circuit. Resistance, capacitance, and inductance are examples of passive elements. The damping ratio is increased when the resistance or capacitance in the circuit is increased. The damping ratio decreases when the inductance in the circuit is increased, as inductors provide energy storage.

Statement 2 is wrong because the frequency of the circuit depends on inductance and capacitance, not resistance. Statement 3 is wrong because no such statement exists.

Answer:

Any amount of force

Explanation:

Any amount of force will overcome inertia, assuming that overcoming inertia means changing the velocity of an object. Looking at Newton's 2nd law: F=m*a, any force applied to a constant mass must effect an acceleration.

If overcoming inertia entails altering an object's velocity, then any amount of force will do it. By applying a force on a mass that is constant, as stated by Newton's second law: F=m*a, an acceleration results.

You only need to know the equation F=ma to comprehend how force overrides inertia; take note that a stands for acceleration, which is the change in speed. Therefore, any net force will cause some acceleration, regardless of how much mass there is or how little force there is. All objects have the propensity to resist changes in motion, which is known as inertia. Unless a force acts on a moving object to modify its speed or direction, inertia causes it to continue traveling at the same velocity (speed and direction). Additionally, it keeps an object in rest still.

The "sum of the product of mass" of each particle with the "square of its distance from the axis of rotation" is the formula for the moment of inertia.

The force is pointing out of the page, and the torque is perpendicular to the page; the torque is clockwise.

In Figure 10-4, the force F2 is 15.0 N and it acts at the point 70.0 cm. What is the magnitude of the torque due to F2 about an axis through point B and perpendicular to the page?The formula for calculating torque (τ) is given as:τ = r x FsinθWhere,τ = torque (N.m)r = perpendicular distance from the axis of rotation to the point where the force is applied (m)F = force (N)θ = angle between the force and the perpendicular distance (r) (in radians)Given:F = 15.0 N r = 70.0 cm = 0.7 mθ = 90° = π/2 rad (since the force is perpendicular to the page)Substituting the values in the formula:τ = r x Fsinθτ = 0.7 x 15.0 x sin(π/2)τ = 10.5 N.mTherefore, the magnitude of the torque due to F2 about an axis through point B and perpendicular to the page is 10.5 N.m.Is the torque clockwise, or is it counter clockwise?We can determine the direction of the torque by applying the right-hand rule. Curl the fingers of your right hand in the direction of the force and then extend your thumb. The direction in which your thumb points is the direction of the torque. Since the force is pointing out of the page and the torque is perpendicular to the page, the torque is clockwise.
In Figure 10-4, the force F2 has a magnitude of 15.0 N and acts at a distance of 70.0 cm from point B. To calculate the torque due to F2 about an axis through point B and perpendicular to the page, we use the formula:
torque = force × distance × sin(theta)
Here, theta is the angle between the force vector and the line connecting the point of application of the force to the axis. Since the force is perpendicular to the distance (from the problem statement), the angle is 90 degrees. The sin(90) is equal to 1. So the torque is simply:
torque = force × distance
torque = 15.0 N × 0.7 m = 10.5 Nm
As for the direction, if the force F2 causes a rotation in the clockwise direction about point B, the torque is positive. If it causes a rotation in the counterclockwise direction, the torque is negative.

Got it right on Edge

Answer:

1) (0,0,10)

2) 10

3) 0.707

Explanation:

1) Given the x,y, and z magnitudes of both T and U, we find V by using the cross product: c = (ay*bz - az*by)i^ + (az*bx - ax*bz)j^ + (ax*by - ay*bx)k^

(i^ = "i hat" etc. sry to confuse)

in this case, I used a=T, b=U, and c=V:

V = (Ty*Uz - Tz*Uy)i^ + (Tz*Ux - Tx*Uz)j^ + (Tx*Uy - Ty*Ux)k^

Now plug in values:

V = (1*0 - 0*4)i^ + (0*2 - 3*0)j^ + (3*4 - 1*2)k^

V = 0i^ + 0j^ + 10k^

These are your components.

2) To get the magnitude of V, you add up the vector components:

sqrt( 0^2 + 0^2 + 10^2)

sqrt(100) = 10

Note: because they are vectors, you must use vector addition with the square root. (do NOT simply add 0 + 0 + 10 = 10.)

3) Lastly it asks for sin(theta), so we can use the equation of:

c = a*b*sin(theta)

Again I input c = V, a = T, b = U:

V = T*U*sin(theta)

Isolate sin(theta) on one side:

sin(theta) = V/(T*U)

To get just T or U, do vector addition once more for their x,y, and z components:

T = Tx + Ty + Tz = sqrt( 3^2 + 1^2 + 0^2) = sqrt( 9 + 1 + 0) = 3.162

U = Ux + Uy + Uz = sqrt( 2^2 + 4^2 + 0^2) = sqrt (4 + 16 + 0) = 4.472

Plug in values:

sin(theta) = V/(T*U) = 10/(3.162*4.472) = 0.707

3. Work done is same as force  = 30N

4. P = 480W

1. Here given:

F = 25N

D = 2m

We have to find  W = ?

Work done Formula : W= F x D

By substituting ,

W = 25 x 2

W = 50J

2. Here given,

F = 15N

Angle = 30°

distance = 3m

W = 15* 3 * cos 30

= 6.9 J

3. Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. When we apply a force of 30N to a wall, it responds with the same force.

4. The work done will be calculated using the formula:

W = mass*gravitational acceleration*height.

Furthermore,

power = work done / time.

500 + 100 = total weight

600 N = total weight

Explanation:

Answer:

To use Snell's law to find N1, we need to know the indices of refraction and angles of incidence and refraction of the two media.

Snell's law states that:

n1 sin(theta1) = n2 sin(theta2)

where n1 and n2 are the indices of refraction of the two media, theta1 is the angle of incidence, and theta2 is the angle of refraction.

We are given n2=2.61, theta1=40°, and theta2=34°. To find N1, we need to rearrange Snell's law to solve for n1:

n1 = n2 sin(theta2) / sin(theta1)

Plugging in the values we have:

n1 = 2.61 sin(34°) / sin(40°)

n1 ≈ 2.22

Therefore, the index of refraction of the first medium (N1) is approximately 2.22, based on the given values and Snell's law.

The magnitude of current in the middle branch is 0.857 A.

Given circuit diagram is:Resistors 2 Ω and 4 Ω are in parallel:

So, equivalent resistance of 2 Ω and 4 Ω is 4/3 Ω now this is in series with 1 Ω resistor, so the total resistance is:R = 1 + 4/3 = 7/3 Ω

Total voltage in the circuit is 10 V.Now, we can use Ohm's law to find the current: I = V / RSo, I = 10 / (7/3) = 30/7 A ≈ 4.29 A

Now, the current is dividing into three branches in the ratio of inverse of resistance of each branch.

Therefore, current through the middle branch is:Im = (1 / (1+2/3)) × 30/7= (1/5) × 30/7 = 6/7 ≈ 0.857 A

Therefore, the magnitude of current in the middle branch is 0.857 A.
