Answer:
almost 100% positive its B but dont take me up on it
Answer:
14.715 m
Explanation:
Assume that the acceleration due to gravity is 9.81 m/s^2 downwards, take downwards as positive
First second:
v = u + at
v = 9.81 m/s
Second second:
s = ut + (1/2)at^2
s = 9.81(1) + (1/2)(9.81)(1)^2
s = 14.715 m
The answer is observation
Answer: Option (c) is the correct answer.
Explanation:
The difference in electrical potential energy between two places in an electric field is known as potential difference.
Mathematically, potential difference between two given points can be written as follows.
where, 
= potential difference
= potential at point 1
= potential at point 2
Answer:
mj = 53.3kg
Explanation:
Since both gravitational energies are the same:
Eb = Ej => mb*g*hb = mj*g*hj
Solving for mj:
mj = mb*hb/hj = 80*2.4/3.6
mj = 53.3kg
