GPE= height x mass x gravitational field strength
5 x 10 x 9,8=490J
Answer:
Change of momentum = M (Vf - (-Vi)) where V represents the scalar speeds of the ball or
I = M (ui + uf) and I is the impulse ΔM V = I Force = Change in Momentum
V = f x lamda
Wave speed = frequency x wavelength
2x1 = 2 so wave speed = 2m/s

Answer:
The current through the bulb when the flashlight is turned on is 0.55 A.
Explanation:
Given that,
You have a flashlight that takes four ideal 1.5 V batteries, voltage of the flashlight, V = 6 V
The resistance of bulb, R = 11 ohms
We need to find the current through the bulb when the flashlight is turned on. As per Ohms's law :
V = IR

So, the current through the bulb when the flashlight is turned on is 0.55 A. Hence, this is the required solution.
