The distance from crest to crest or from trough to trough of a wave is called the wavelength.

A wavelength is the distance between two consecutive points on a wave that are in phase with each other, such as two adjacent crests or two adjacent troughs. In other words, it is the distance between any two points on a wave that are at the same point in their cycle of motion.

Wavelength is an important characteristic of any wave, including electromagnetic waves (such as light and radio waves), sound waves, and water waves. It is usually denoted by the Greek letter lambda (λ) and is expressed in units of length, such as meters (m), centimeters (cm), or nanometers (nm).

Using velocity and acceleration, a. To determine the location of the car when its velocity is zero, we must identify the roots (time instances) of the velocity equation, which is the first derivative of the position equation.

The velocity equation is as follows: \(v(t) = (9.60m/s^3) t - (0.600m/s^7)t^7.\)

To find the roots of this equation, we can use numerical techniques like Newton-Raphson or bisection. The velocity equation can also be seen to be a seventh-degree polynomial with up to seven roots. By setting the velocity equation to zero and calculating the root, we can apply a numerical solution or perform a hand calculation to obtain the first root (i.e., the first time the car has zero velocity).

b. The formula for the acceleration equation, which is the second derivative of the position equation, is: \(a(t) = (9.60m/s^2) - (6.00m/s^6)\)\(t^6\)

Answer:

The sea bed is 1125 m deep.

Explanation:

Speed

It's the rate of change of the distance (d) traveled by an object over time (t).

The speed can be calculated by the formula:

\(\displaystyle v=\frac{d}{t}\)

It's known the speed of sound in water is v=1500 m/s. A sound wave is sent to the sea bed and bounces back to the ship 1.5 seconds later.

That is the time the wave takes to travel twice the distance from the ship to the sea bed, thus the required distance uses half of that time or t=1.5/2 = 0.75 seconds.

Solving the equation for d:

d = v.t

d = 1500 m/s * 0.75 s

d = 1125 m

The sea bed is 1125 m deep.

Measurement of the distance traveled and the amount of time required to cover that distance are required in order to determine speed.

The force of gravity causes objects to accelerate back to earth at a rate of  9.8 m/s^2

Gravity is the force of attraction between any two objects with mass. The strength of this force depends on the masses of the two objects and the distance between them. The larger the masses of the objects, the stronger the gravitational force between them will be. Similarly, the closer two objects are to each other, the stronger their gravitational attraction will be.

When an object is dropped or thrown, the force of gravity immediately begins to pull it back towards the earth. This force causes the object to accelerate downwards, meaning that its velocity (speed and direction of motion) increases over time. The rate at which this acceleration occurs is constant and is equal to approximately 9.8 m/s^2

Answer:

the velocity of the boats after the collision is 4.36 m/s.

Explanation:

Given;

mass of fish, m₁ = 800 kg

mass of boat, m₂ = 1400 kg

initial velocity of the fish, u₁ = 12 m/s

initial velocity of the boat, u₂ = 0

let the final velocity of the fish-boat after collision = v

Apply the principle of conservation of linear momentum for inelastic collision;

m₁u₁ + m₂u₂ = v(m₁ + m₂)

800 x 12    +   1400 x 0 = v(800 + 1400)

9600 = 2200v

v = 9600/2200

v = 4.36 m/s

Therefore, the velocity of the boats after the collision is 4.36 m/s.

Frictional Force = 1.8 N

Explanation:

From Newton's Second Law, we know that the acceleration is produced in an object, whenever an unbalanced force is applied to it. So, for the production of acceleration application of an unbalanced force is necessary. Since, the block is moving with uniform speed in this case. Therefore, there is no acceleration involved in the motion of block. So, the all the forces acting on the block must cancel the effect of each other. So, that there is no unbalanced force to produce any acceleration. Therefore, the frictional force must be equal to the applied force in order to cancel its effect and balance it.

Frictional Force = Applied Force

Frictional Force = 1.8 N

If a system has 46.5 j of heat added to it, and the system does 75.5 j of work on its surroundings. 29 j is the change in the internal energy of the system.

Internal energy refers to the energy that exists within the system. It is represented by the letter "U" in English.

Thermal energy is another name for internal energy. It is the energy of a substance as a result of the kinetic and potential energies connected to the ad hoc motion of all the constituent particles.

Internal energy, which is measured in KJ or Joule, is the energy attributed to the chaotic arrangement or random motion of particles within the system. Using the formula for internal energy, we can calculate the same.

The difference between the heat flow in a system and the work done by or on the system (PV) equals the change in internal energy, and the change in internal energy formula aids in calculating the same.

Energy Equation within the energy of the universe is constant, in accordance with the basic law of thermodynamics.

Additionally, the sum of the work done and the heat transported is equal to the change in a system's internal energy.

Additionally, the sum of the change in the system's internal energy and the work performed by the PV system equals the heat added or flown.

The Change in Internal Energy Formula is:

                    ΔU  =  Q  +  W

Here,

U =  the total change in internal energy within the system

Q =  the heat exchanged between a system and its surroundings (outside the system)

The answer to your question would be number 2 amplitude and frequency are the same so the higher the frequency the higher the amplitude. As you can see in the picture wave E has the  highest frequency. which means since A has the lowest  frequency and E has the highest frequency answer 2 would be correct the amplitude increases from A to E.

Amplitude of a wave is the strength of the wave. It is measured from the central line of the wave to the top of the crest or bottom of the trough. Thus, higher amplitude waves will gives sharp crests and troughs. Here amplitude is increasing from A to E.

Amplitude is a parameter measuring the strength of a wave. It is the maximum displacement moved by the wave from its equilibrium position. The vibrational path will be twice that of the amplitude of the wave.

As the amplitude of the wave increases its intensity increases. Both are in direct proportion with the frequency and energy of a wave. For instance the amplification of sound waves increases the intensity of waves that we hear.

The distance between two consecutive crests or troughs is the wavelength of the wave not amplitude. Amplitude is measured from the axis line to the top of the crest thus, from exact middle of the wave crest to the top or to the bottom of trough.

Thus, higher amplitude waves will gives sharp crests and troughs. Here amplitude is increasing from A to E

The force constant of the spring is 200.696 N/m & The height the object achieves when the spring releases its energy is 2.5087 m

The spring constant is the force needed to stretch or compress a spring, divided by the compressive or expansive distance. It's used to determine stability or instability in the spring, and therefore the system it's intended for. we know,

F = kx

Therefore,

k = F/x

We also know that the force being exerted on the spring is equal to the mass of the object. Hence, F = mg = 5.13 * 9.8 N = 50.174 N and we know compression due to the mass is 0.25m. Therefore,

K = 50.174/0.25 N/m

K = 200.696 N/m

Therefore, The Spring Constant is 200.696 N/m

On release, the spring potential energy gets converted to kinetic energy. Hence, on release, the height attained by the object is given by:

h = \(1/2 kx^{2}\)

We know that k=200.696 N/m and x=0.25 m. Therefore the height is:

h = \(1/2 (200.696 N/m)(0.25 m)^{2}\)

h = 2.5087 m

Therefore, the force constant of the spring is 200.696 N/m & The height the object achieves when the spring releases its energy is 2.5087 m
