Its an example of newton's 2nd law
Answer:
None
Explanation:
Since the object is not moving any distance, no matter how big of a force you are exerting you are not actually doing any work since W=Fd. Hope this helps!
Answer:
Explanation:
Given,
Mass of ball kg
Speed of ball m/s
Mass of persona kg
(a) The person is at rest initially. So, by the conservation of momentum
(b) Final speed of ball
Inductive reactance (Z) = ω L = 2Πf L = (2Π) (12,000) (L)
I = V / Z
4 A = 16v / (24,000Π L)
Multiply each side by (24,000 Π L):
96,000 Π L = 16v
Divide each side by (96,000 Π) :
L = 16 / 96,000Π = 5.305 x 10⁻⁵ Henry
L = 53.05 microHenry
I hope my answer helped you
