1 A ("Ampere") means 1 C ("Coulomb") of charge per second.
It shouldn't surprise us to learn, then, that 6.0 A means 6.0 C per second.
If 6 C pass by every second, then 24 C will pass by in (24/6) = 4 seconds .
Answer:
Where the electric potential is constant, the strength of the electric field is zero.
Explanation:
As a test charge moves in a given direction, the rate of change of the electric potential of the charge gives the potential gradient whose negative value is the same as the value of the electric field. In other words, the negative of the slope or gradient of electric potential (V) in a direction, say x, gives the electric field (Eₓ) in that direction. i.e
Eₓ = - dV / dx ----------(i)
From equation (i) above, if electric potential (V) is constant, then the differential (which is the electric field) gives zero.
<em>Therefore, a constant electric potential means that electric field is zero.</em>
The sun is the primary source of light. Other artificial sources are light bulb, torch light and some others. Thats all i can think of.
Answer:
Explanation:
Given that,
The length of a string, l = 0.87 m
Speed of the ball, v = 3.36 m/s
We need to find the acceleration of the ball. The acceleration acting on the ball is centripetal acceleration. It is given by :
So, the acceleration of the ball is .
