Answer:
Centripetal force acting on the body = 9.47 N
Explanation:
Mass of body, m = 2 kg
Radius, r = 3 m
It makes one revolution in 5 seconds.
Period, T = 5 s
Centripetal force, F = mrω²
F = 2 x 3 x 1.256² = 9.47 N
Centripetal force acting on the body = 9.47 N
Answer:
25 ohms
Explanation:
Hi there!
Ohm's law states that where V is voltage, I is current and R is resistance.
Plug the given information into Ohm's law (V=50, I=2) and solve for R
Divide both sides by 2 to isolate R
Therefore, there are 25 ohms of resistance present in this circuit.
I hope this helps!
