Answer:
(a) and (b)
Both will follow the rule
This is due to property of charges.
As in case of gravitational potential energy as it increases as height increases.
In case of electrical potential energy it will increase as charges comes close.
Explanation:
have a good day:))
To solve this problem we will apply the principle of conservation of energy. For this purpose, potential energy is equivalent to kinetic energy, and this clearly depends on the position of the body. In turn, we also note that the height traveled is twice that of the rigid rod, therefore applying these concepts we will have
Therefore the minimum speed at the bottom is required to make the ball go over the top of the circle is 4.67m/s
Answer:
The answer to your question is the letter C. 3 Watts
Explanation:
Data
Power = ?
Force = 20 N
Distance = 1.5 m
time = 10 s
Formula
Work = force x distance
Power = Work/time
Process
a) Calculate the Work
Work = 20 x 1.5
Work = 30 J
b) Calculate the Power
Power = 30J/10s
Power = 3 Watts
The units of Power are Watts and the units of Work and energy are Joules.
