The Answer is Option C
I think...
Sorry If i am wrong...
Answer:
108.7 V
Explanation:
Two forces are acting on the particle:
- The external force, whose work is 
- The force of the electric field, whose work is equal to the change in electric potential energy of the charge: 
where
q is the charge
is the potential difference
The variation of kinetic energy of the charge is equal to the sum of the work done by the two forces:
and since the charge starts from rest, 
, so the formula becomes
In this problem, we have
is the work done by the external force
is the charge
is the final kinetic energy
Solving the formula for , we find
80 km per hour i believe. i’ll admit i’m american so we don’t use km lol, but the math should be the same. total distance = 120km, and total time = 1.5 hours. 120/1.5 = 80.
The movement of the earth is so small, especially compared to you, that you don't realize it. This is because the earth's mass is so much greater than your mass.
Answer:
23 m
Explanation:
If acceleration is uniform then
distance = ( average velocity ) × time
= ( (initial velocity +final velocity )/2 ) × time
= (( 1.5 + 1.0) /2 ) × 18.4
= ( 2.5/2 ) × 18.4
= 1.25× 18.4
= 23 m
