The position of John at time of 4.35 s is -1.13 m
From the given chart;
- at time, t = 0, the initial velocity, u = - 2 m/s
- at time, t = 5 s, the final velocity, v = 2 m/s
The average acceleration is calculated as follows;

Thick lens will have shorter and consequently thin lens will have greater focal length. Because, For a thick lens, the optical path length of the light is more, than for a thin lens, thus, the bending of light will be more in case of a thicker lens. Consequently, it has a shorter focal length.
Answer:
ΔV = -2.1 L
Explanation:
To solve this exercise we can use the ideal gas equation for two points
PV = nRT
P₁V₁ = P₂ V₂
where point 1 is on the surface and point 2 is at the desired depth,
V₂ =
let's calculate
V₂ = ( ) 3.5 L
V₂ = 1.4 L
this is the new volume, the change in volume is
ΔV = V₂ -V₁
ΔV = 1.4-3.5
ΔV = -2.1 L
The frequency will not change
Answer:
It keeps particles that make up protons and neutrons together.
Explanation:
Nuclear force is a short range of force which means it will act at short range of distance like fermi order distance.
This shows the order of radius of the nuclei which means all the neutrons and protons which resides into the nucleus will exert the nuclear force on each other and this nuclear force is of large magnitude compare to electrostatic force or gravitation force between them.
While if the distance is more than the fermi order distance then the nuclear force totally disappears so it will not exist for large distances.
so here the correct answer must be
It keeps particles that make up protons and neutrons together.
