Answer:
20.353125 V
Explanation:
m = Mass of proton = 
q = Charge of proton = 
= Velocity of proton at point A = 50 km/s
= Velocity of proton at point B = 80 km/s
The relationship derived from energy conservation is as follows:

The determined potential difference is 20.353125 V
Answer:
11.56066 m/s
Explanation:
m = Mass of individual
v = Velocity of individual = 13.4 m/s
g = Gravitational acceleration = 9.81 m/s²
v' = Velocity of the individual after dropping
At the surface, kinetic and potential energy will equalize

The cliff's height is 9.15188 m
Define fall height as h' = 2.34 m

The person's speed is 11.56066 m/s
Answer:
The equivalent distance in kilometers is 4012 ×
km.
Explanation:
It's known that 1 millimeter converts to
meters. Then, 1 meter converts to
kilometers. Therefore, the conversion for 1 millimeter to kilometers can be stated as
1 mm =
m
1 m =
km
Thus, 1 mm =
×
km =
km.
Given the distance of 4012 mm, the corresponding distance in kilometers will be
4012 mm = 4012 ×
km.
The distance therefore is 4012 ×
km.
Answer:
Explanation:
Let us denote the launch angle as
.
,
, and
are complementary angles which means their ranges are identical.



Time of flight is indicated as
