Answer:
All
Explanation:
I'm not sure what you meant but Newton's third law which basically states that every action has an equal and opposite reaction applies to <em>all</em> objects. So I think the answer is all.
Answer:
Explanation:
Thomas Young (1773 − 1829) first introduced the word “energy” to the field of physics in 1800, but the word did not gain popularity. Thomas Young later established the wave nature of light through interference experiments.
Answer:
0.31 T
Explanation:
N = 1750
R = 30 ohm
A = 5 x 10^-4 m^2
B1 = 0 T
q = 9 x 10^-3 C
Let the magnetic field is B ad the time is t.
B2 = B
Use the Faraday's law of electromagnetic induction
e = dФ / dt
i R = N x A x (B2 - B1) / t
i x R / t = N x A x B
q x R = N x A x B
9 x 10^-3 x 30 = 1750 x 5 x 10^-4 x B
B = 0.31 T
