Explanation:
well there is nothing there and it could be different by diffrent objects, idk
A 60.0 kg secretary running up a 4.0 m tall flight of stairs in 4.2 s has an average power of 560 W (Option b).
<h3>What is power?</h3>
Power is the work done over a period of time.
A secretary with a mass (m) of 60.0 kg runs up a 4.0 m (d) tall flight of stairs. Given gravity (g) is 9.81 m/s², the work (W) done is:
W = m × g × d = 60.0 kg × 9.81 m/s² × 4.0 m = 2.35 × 10³ J
They do 2.4 × 10³ J of work in 4.2 s (t). The average power (P) is:
P = W / t = 2.35 × 10³ J / 4.2 s = 560 W

Answer:
0.459 Tesla
Explanation:
Faraday's law:

Φ= NAB
V = N Δ (BA) /Δt
the change in BA
was: BA = 0 because initially B was zero.
V=IR
IR = N B A /Δt
q / Δt ×R = N B A / Δt
Or: B = q R / NA = 8.87 x 10^-3 × 45.0 / 1850×4.7 x 10^-4 =
= 0.459 Tesla
