A vertical piston-cylinder device initially contains 0.1 m^3 of air at 400 K and 100 kPa. At this initial condition, the piston is resting on a stop. The piston-cylinder device is connected to a supply line with air at 400 K and a pressure of 500 kPa. The valve between the supply line and the piston-cylinder device is opened and is left open until the pressure in the piston-cylinder device reaches 500 kPa. The piston is observed to start moving when the pressure in the cylinder is 200 kPa and the piston continues to rise until it reaches a second stop. At the second stop, the piston-cylinder volume is 0.2 m^3 . The final temperature and pressure in the piston-cylinder device are 440 K and 500 kPa, respectively.

a bullet of mass 120g is fired horizontally into a fixed wooden block with a speed of 20m\s. The bullet is brought to rest in a wooden block in 0.1secs by a constant resistance
calculate the;(I) magnitude of the resistance
(ii) distance moved by the bullet in the wood
Answer:
1) F = 24 N
2) Distance = 1 m
Explanation:
We are given;
Mass; m = 120 g = 0.12 kg
Initial velocity; u = 20 m/s
Final velocity; v = 0 m/s since it came to rest.
Time; t = 0.1 s
We can calculate acceleration from Newton's first equation of motion;
a = (v - u)/t
a = (0 - 20)/0.1
a = -200 m/s²
1) magnitude of the resistance will be;
F = ma
F = 0.12 × (-200)
F = -24 N
Since, we are dealing with the magnitude, we will take the absolute value. Thus, F = 24 N
2) To find the distance moved by the bullet, we know that;
Distance = Average speed × time
Thus;
Distance = ((v + u)/2) × t
Distance = ((0 + 20)/2) × 0.1
Distance = 1 m
discuss impact of Newton's second law on roads
Answer:
The second law: When a force is applied to a car, the change in motion is proportional to the force divided by the mass of the car. This law is expressed by the famous equation F = ma, where F is a force, m is the mass of the car, and a is the acceleration, or change in motion, of the car

:D
Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.
What is nuclear fusion?The process by which two or more tiny nuclei unite to generate a bigger nucleus is known as a nuclear fusion reaction.
The more energy it takes to liberate an electron from a smaller atom. This is referred to as binding energy.
As a result, when two little nuclei fuse together, there is more binding energy than when two big nuclei fuse together.
For example, the fusion of two hydrogen atoms produces more energy than the fusion of one helium atom, and surplus energy is expelled into space upon binding.
Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.
Hence option D is correct.

The diagram above shows the pipes now, before they have touched. Use the information in the diagram to answer the question.
How does the temperature of the front pipe compare with the temperature of the back pipe before the pipes touch? What will happen after the pipes have been touching for a while?
Answer:
They become the same exact tempature
Explanation:
Since they got connected it should be the same.
the temperature of the front pipe compare with the temperature of the back pipe before the pipes touch by using same temperature.
what is temperature ?Temperature is the measure of hotness or coldness expressed in terms of any of several arbitrary scales and it indicate the direction in which heat energy will spontaneously flow from a hotter body to a colder body.
It is not the equivalent of the energy of a thermodynamic system like burning match is at a much higher temperature than an iceberg whereas the total heat energy contained in an iceberg.

10. A jogger runs along a road for a distance of 2700 m. If it takes her 900 seconds
to run that distance, what is her speed?
Answer:
Speed = 3 m/s
Explanation:
Given the following data;
Distance = 2700m
Time = 900 s
To find the speed;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the formula;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting into the equation, we have;
[tex]Speed = \frac{2700}{900}[/tex]
Speed = 3 m/s
A person starts running from 2 m/s to 6 m/s in 2 seconds.

Two charges are separated by a distance r. The distance between the charges is tripled to 3r. If the original force between the charges was 45N what is the new force between the charges A.5N B.15N C.75N D.135N
Answer:
5N
Explanation:
The formula formula for calculating the force between charges is expressed as;
F = kq1q2/r²
If two charges are separated by a distance r and a force between them is 45N, then;
45 = kq1q2/r² ....1
If the distance between the charges is tripled to 3r, then;
F = kq1q2/(3r)²
F = kq1q2/9r² ... 2
Divide both expressions
45/F = (kq1q2/r²)/(kq1q2/9r²)
45/F = kq1q2/r² * 9r²/kq1q2
45/F = 9
9F = 45
F = 45/9
F = 5N
Hence the new force between them will be 5N

A microphone is attached to a spring that is suspended from the ceiling, as the drawing indicates. Directly below on the floor is a stationary 375-Hz source of sound. The microphone vibrates up and down in simple harmonic motion with a period of 1.80 s. The difference between the maximum and minimum sound frequencies detected by the microphone is 2.75 Hz. Ignoring any reflections of sound in the room and using 343 m/s for the speed of sound, determine the amplitude (in m) of the simple harmonic motion.
Answer:
[tex]0.361\ \text{m}[/tex]
Explanation:
[tex]f_s[/tex] = Frequency of source = 375 Hz
[tex]\Delta f[/tex] = Difference between the maximum and minimum sound frequencies = 2.75 Hz
v = Speed of sound in air = 343 m/s
T = Time period = 1.8 s
[tex]v_m[/tex] = Maximum speed of the microphone
We have the relation
[tex]\Delta f=2f_s\dfrac{v_m}{v}\\\Rightarrow v_m=\dfrac{\Delta fv}{2f_s}\\\Rightarrow v_m=\dfrac{2.75\times 343}{2\times 375}\\\Rightarrow v_m=1.26\ \text{m/s}[/tex]
Amplitude is given by
[tex]A=\dfrac{v_mT}{2\pi}\\\Rightarrow A=\dfrac{1.26\times 1.8}{2\pi}\\\Rightarrow A=0.361\ \text{m}[/tex]
The amplitude of the simple harmonic motion is [tex]0.361\ \text{m}[/tex].
calculate the magnitude of distance and displacement of a body moving in a complete circle
Answer:
Total distance = 2πr
Total displacement = 0
Explanation:
To Calculate the magnitude of distance and displacement of a body moving in a complete circle, we must come to these facts that:
The distance = circumference of the circle which is equal to the product of 2 ,pi and radius r
That is
Circumference = 2πr
Since velocity is changing and not constant, it is a vector quantity. Likewise displacement is a vector quantity.
The total displacement will be equal to zero.
Therefore, total distance is equal to the circumference of a circle while total displacement is equal to zero.
A 100 N force is applied to move an object a horizontal distance of 5 meters at constant speed in 10 seconds. How much power is done?
The power used when a 100 N force is applied to move an object through a distance of 5 m at constant speed in 10 seconds is 50 W
We'll begin by calculating the energy. This can be obtained as follow:
Force (F) = 100 N
Distance (s) = 5 m
Energy (E) =?E = F × s
E = 100 × 5
E = 500 JFinally, we shall determine the power. This can be obtained as follow:
Energy (E) = 500 J
Time (t) = 10 s
Power (P) =?[tex]P = \frac{E}{t}\\\\P = \frac{500}{10}[/tex]
P = 50 WTherefore, the power used in moving the object is 50 W.
