Although we do not have the diagram needed to answer this question, we can provide general information in that electrical potential energy is calculated based on the charges and the distance between them.
How do we calculate electric potential energy?This energy can be calculated using the value of the charges along with the distance between them with the formula Energy = [tex]k\frac{q1q2}{r}[/tex] in which q represents the charges whilst r represents the distance of separation. As we can see these values are inversely proportional to one another.
Therefore, we can confirm that we can calculate electric potential energy using the charges and the distance between them, which will be inversely proportional to one another.

A person walks up a stalled 10 m long escalator in 94 s. When standing on the same escalator, now moving, the person is carried up in 60 s. How much time would it take that person to walk up the moving escalator?
Answer:
V1 = S / t1 = speed up stalled escalator = 10/94 = .106 m/s
V2 = S / t2 = speed of escalator = 10 / 60 = .167 m/s
V = V1 + V2 combined speed
T = S / V = 1 / t1 + 1 / t2 = t1 * t2 / (t1 + t2)
T = 60 * 94 / (60 + 94) = 36.6 sec
Check: combined speed = .106 + .167 = .273 m/s
T = 10 / .273 = 36.6
What is the momentum of a 12-kg object moving at 5.5 m/s?
Answer: 66 kg m/s
Explanation:
The equation for Momentum is
p=mv
where P is momentum
m is mass
and v is velocity (speed)
Since we have both mass and velocity all we have to do is multiply the mass and velocity to get momentum
12kg * 5.5 m/s = 66 kg m/s

A person throws a ball with a force of 140 N that accelerates at 15 m/s? What is the mass of the
ball?
Newton's 2nd law
[tex]\tt \sum F=m.a[/tex]
input the value:
[tex]\tt m=\dfrac{\Sum F}{a}=\dfrac{140~N}{15~m/s^2}=9.3~kg[/tex]
The mass of the ball, that person throws, is 9.33 kg.
What is force?The definition of force in physics is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.
The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.
A spring balance can be used to calculate the Force. Newton is the SI unit of force.
Force applied on the ball = 140 N.
Acceleration of the ball = 15 m/s².
According to Newton's 2nd law of motion:
Force = mass × acceleration
Mass = force ÷ acceleration
= 140 N ÷ 15 m/s²
= 9.33 kg.
Hence, the mass of the ball is 9.33 kg.

An engineer is designing a runway. She knows that a plane, starting at rest, needs to reach a speed of 180mph at take-off. If the plane can reach this take-off speed in 65.0s, how far will the plane travel before take-off. Assume the plane increases speed steadily.
How far does the plane need to travel during take-off (in given units)?
ft
Could the plane take off on a 10000ft long runway?
Answer:
The plane would need to travel at least [tex]8,\!580\; {\rm ft}[/tex] ([tex]8.58 \times 10^{3}\; {\rm ft}[/tex].)
The [tex]10,\!000\; {\rm ft}[/tex] runway should be sufficient.
Explanation:
Convert unit of the the take-off velocity of this plane to [tex]\rm ft\cdot s^{-1}[/tex]:
[tex]\begin{aligned}v &= 180\; {\rm mph} \\ &= 180\; {\rm mi \cdot hrs^{-1}} \times \frac{1\; {\rm hrs}}{3600\; {\rm s}} \times \frac{5280\; {\rm ft}}{1\; {\rm mi}} \\ &= 264\; {\rm ft \cdot s^{-1}}\end{aligned}[/tex].
Initial velocity of the plane: [tex]u = 0\; {\rm ft \cdot s^{-1}}[/tex].
Take-off velocity of the plane [tex]v =264\; {\rm ft\cdot s^{-1}}[/tex].
Let [tex]x[/tex] denote the distance that the plane travelled along the runway. Since acceleration is constant but unknown, make use of the SUVAT equation [tex]x = ((u + v) / 2) \, t[/tex].
Notice that this equation does not require the value of acceleration. Rather, this equation make use of the fact that the distance travelled (under constant acceleration) is equal to duration [tex]t[/tex] times average velocity [tex](u + v) / 2[/tex].
The distance that the plane need to cover would be:
[tex]\begin{aligned}x &= \left(\frac{u + v}{2}\right)\, t \\ &= \frac{0\; {\rm ft \cdot s^{-1}} + 264\; {\rm ft \cdot s^{-1}}}{2} \times 65.0\; {\rm s} \\ &= 8.58\times 10^{3}\; {\rm ft}\end{aligned}[/tex].

Answer:
V1 A1 = V2 A2
V1 = 10m/s
A1 = 8m
10x8 =80
V2 =?
A2 = 4m
80 = V2 x 4
÷4
20 = V2
V2 =20m/s
Explanation:
If one halfs, the other doubles & vice versa. (Like inverse proportion or the reciprocal). That's why when you half 8m, the velocity doubles, on the other side. Then, balances out.

Is hookes law applicable to all materil?
Answer:
Hooke’s law can be applied to all materials which come back to original shape upon withdrawal of the load. It is applicable to all materials which follow the linearity of stress and strain in the elastic limit. Any object made of steel or aluminum or any other metals that follows the stress-strain linearity in the elastic zone uses Hooke’s law.
Explanation:
Answer:
No.
Materials which obeys Hook's law are called elastic material.
Elastic material are material which return to their original shape and size after force deforming them is removed.

If a car is moving +14m/s is to stop within 2 seconds, what must the car's acceleration be?
Acceleration is -7 m/s²
Explanation:
initial velocity (u) = 14 m/s
since it's gonna stop,
final velocity (v) = 0m/s
time taken(t) = 2 seconds
now,
a = (v-u)/t
or, a = (0-14)/2
or, a = -14/2
a = -7m/s²

1. A rock of granite has a mass of 50 kg. if it’s weight in water
W2 = 380 N [ density = 1000 kg/m3] Calculate FB and the volume of the rock.[g =10 m/s2]
Answer:
The first part of the question is asking about BUOYANT FORCE or UPTHRUST.
Upthrust =TRUE WEIGHT-APPARENT WEIGHT
TRUE WEIGHT=mg
TRUE weight=50kg×10m/s²
=500N
upthrust=500N-380N
FB=120N
volume of the rock=mass/density.
since the granite is completely submerged, the volume of the displaced liquid will be equal to the volume of the body.
upthrust=Vdg
120N=V×1000kg/m³×10m/s²
120N=V×10000kg/m²s²
120/10000=V
v=0.012m³

An equal amount of a gas is held in two identical containers. The temperature of container 1 is 15°C and the temperature of container 2 is 30°C. In which container will the pressure be lowest? (Assume there is nothing else inside the containers.)
Answer:
Container 1
Explanation:
The reason why there will be less pressure in container 1 is that it's colder than container 2. You must have learned right, that a colder thing has its molecules less moving, and they don't expand, instead they actually decrease in volume? In the same way, it's applied to gas also. So that's why, because container 1 has 15C temperature, which is half less than container 2's 30C, that's why, container 1 has less pressure than Container 2.
So hence, container 1 has less pressure than container 2 because of its a lower temperature, which doesn't make the molecules expand, and move around that much.

Which line shows the object is moving at its fastest rate of speed?
Answer:
Line C
Explanation:
Hi there!
Speed is equal to Distance divided by Time:
speed = distance / time
Notice how distance is the dependent value on the graph, lying on the y-axis, and time is the independent value on the graph, lying on the x-axis.
The slope of a line is equal to Rise divided by Run:
slope = rise / run
"Rise" means the number of units the line travels up in the y-direction and "run" means the number of units the line travels to the right in the x-direction.
This makes the "rise" of the line equivalent to the distance, and the "run" of the line equivalent to time.
Therefore, speed = slope.
To find the line that shows the object moving at its fastest speed, we must find the line with the greatest slope (or the steepest going up).
That would be line C.
