(ii) Describe how the acceleration of the train at time t = 100 s differs from the acceleration
at time t = 20 s.
Answers
Explanation:
Acceleration is the rate of change of velocity with time. When acceleration increases a body moves a faster velocity.
In the graph acceleration at time t= 100s is rapidly increasing. At t = 20s, the acceleration of the body is getting started up.A vehicle at time 100s will have a faster velocity compared to one at t = 20s

What is the similarities and differences of the particle motion in solid and liquid
Answers
Answer: Differences: Solids have particles that are tightly packed and they form a pattern. In this case, they move and vibrate in place. On the other hand, liquid particles are close together but they have an irregular arrangement. The spaces between the particles allow them to move freely.
Explanation:
Particles in solids are arranged in a pattern and are closely packed. In this instance, they remain stationary and vibrate. However, despite being close together, liquid particle arrangements are asymmetrical. The particles can travel freely because of the voids between them and the similarity is both solid and liquid has some shape, but gas does the random movement in the container.
What is Particle motion in Solid, Liquid and Gas?In solid the particles are tightly packed with each other, so there will be no such movement by the particles it means that there the particles have very less kinetic energy. Solids have definite shape and size, and they are incompressible in nature, and they are tough and rigid as well.
In liquid the particles are lightly packed with each other due to which there is some movement in the particles it means that the particles have some kinetic energy. The liquids are compressible in nature. They do not have a specific shape, but they can take the shape of a container where it is filled.
Liquids are fluid in nature.
In gases, there is so much of distance between particles due to which the particles do random movement, and they have high kinetic energy. They do not have any shape and size, but they are highly compressible as compared to solid and liquid. They also take the shape of the container where they filled.

An Earthquake has caused this, I know this because of the rubble. I know it's not a tornado or something similar because this building has collapsed, not blown away neither has it been lifted a few feet from where it used to be and the building next to it is damaged but still standing. Many earthquakes that are violent enough have the power to make buildings collapse, because of the vibration of the ground. Earthquakes are usually caused when rock underground suddenly breaks along a fault. So an earthquake is actually the result of sudden releases of high energy that take place from the crust of Earth. Since an earthquake leads to travelling waves of high intensity, such waves can easily give a jolt or shock to any building. So in conclusion I think an earthquake caused this in the picture because many earthquakes that are violent enough have the power to make buildings collapsed, because of the vibration of the ground.

Complete Question
A series RLC circuit has R = 405 Ω, L = 1.40 H, C = 3 µF. It is connected to an AC source with f = 60.0 Hz and ΔVmax = 150 V. What if the frequency is now increased to f = 69 Hz, and we want to keep the impedance unchanged? (A) What new resistance should we use to achieve this goal? R = Ω (B) What is the phase angle (in degrees) between the current and the voltage now? ϕ = ° (C) Find the maximum voltages across each element.
Answer:
A
[tex]R = 513.9 \ \Omega[/tex]
B
[tex]\theta = 34.79^o[/tex]
C
[tex]V_c =212.96 \ V[/tex] , [tex]V_L = 168.139 \ V[/tex] , [tex]V_R = 142.35 \ V[/tex]
Explanation:
From the question we are told that
The resistance is [tex]R = 405 \ \Omega[/tex]
The inductance is L = 1.40 H
The capacitance is [tex]C = 3 \mu F = 3 *10^{-6} \ F[/tex]
The original frequency is [tex]f = 60 \ Hz[/tex]
The new frequency is [tex]f_1 = 69 \ Hz[/tex]
Generally the reactance of the inductor is mathematically represented as
[tex]X_L = 2 \pi * f * L[/tex]
=> [tex]X_L = 2 * 3.142 * 60 * 1.40[/tex]
=> [tex]X_L = 527.5 \ \Omega[/tex]
Generally the reactance of the capacitor is mathematically represented as
[tex]X_c = \frac{1}{2 \pi * f * C}[/tex]
[tex]X_c = \frac{1}{2 * 3.142 * 60 * 3*10^{-6}}[/tex]
=> [tex]X_c = 884.6 \ \Omega[/tex]
Generally the impedance of the circuit is mathematically represented as
[tex]Z = \sqrt{[X_L - X_c ]^2 + R^2}[/tex]
=> [tex]Z = \sqrt{[527.5 -884.6 ]^2 + 405^2}[/tex]
=> [tex]Z = 540 \ \Omega[/tex]
Generally when the frequency is changed , the reactance of the inductor becomes
[tex]X_L' = 2 * 3.142 * 69 * 1.4[/tex]
=> [tex]X_L' = 607 \ \Omega[/tex]
Generally when the frequency is changed , the reactance of the capacitor becomes
[tex]X_c' = \frac{1}{2 * 3.142 * 69 * 3*10^{-6}}[/tex]
=> [tex]X_c ' = 768.8 \ \Omega[/tex]
Generally the new resistance is mathematically represented as
[tex]R ^2 = Z^2 - ( X_c' - X_L')^2[/tex]
=> [tex]R ^2 = 540^2 - ( 603 - 768.8 )^2[/tex]
=> [tex]R = \sqrt{264110.4}[/tex]
=> [tex]R = 513.9 \ \Omega[/tex]
Generally the phase angle is mathematically represented as
[tex]\theta = tan^{-1}[\frac{[X_L - X_C]}{R} ][/tex]
=> [tex]\theta = tan^{-1}[\frac{[ 884.6 - 527.5]}{513.92} ][/tex]
=> [tex]\theta = 34.79^o[/tex]
Generally the maximum current flowing through the circuit is mathematically represented as
[tex]I_{max} = \frac{\Delta V}{ Z}[/tex]
=> [tex]I_{max} = \frac{150}{540 }[/tex]
=> [tex]I_{max} = 0.2778 \ A[/tex]
Generally the maximum voltage across the capacitor is
[tex]V_c = I_{max} * X_c'[/tex]
[tex]V_c = 0.2778* 768.8[/tex]
=> [tex]V_c =212.96 \ V[/tex]
Generally the maximum voltage across the inductor is
[tex]V_L = I_{max} * X_L[/tex]
[tex]V_L = 0.2778* 607[/tex]
=> [tex]V_L = 168.139 \ V[/tex]
Generally the maximum voltage across the resistor is
[tex]V_R = I_{max} * R[/tex]
[tex]V_R = 0.2778* 513.9[/tex]
=> [tex]V_R = 142.35 \ V[/tex]

what factors limit the accuracy of a potentiometer and what was the objective of reversing the terminals of the cell
Answers
Explanation:
"The accuracy of a potentiometer can be increased by decreasing the potential gradient across the potentiometer wire, and this can be achieved by increasing the length"
The factors that are affecting/limiting the accuracy of the potentiometer are:
The specific resistance of the material of the potentiometer wire.The potential gradientThe current passing through the potentiometer wire. Area of a cross-section of the wire Internal temperature.
The objective of reversing the terminals of the cell
If the jockey of the potentiometer is pressed for a long time, joule heating sets in, so that reversing the terminals of the potentiometer will prevent the resistance due to joule heat from being added to the measured resistance, ultimately preventing unwanted resistance

Answers
Answer:
Its the 2nd law of motion
Explanation:
Because it talks about force and acceleration
Throwing a ball with more force to increase acceleration is an example of Newton’s 2nd law of motion.
What is Newton's second law of motion?The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.Newton’s second law states that the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object. The acceleration of the body is directly proportional to the net force acting on the body and inversely proportional to the mass of the body. This means that as the force acting upon an object is increased, the acceleration of the object is increased. Likewise, as the mass of an object is increased, the acceleration of the object is decreased.To learn more about Newton’s second law, refer to: https://brainly.com/question/19030143
