Answer:
b) 67.5 N
Explanation:
Force (F) = mass (m) × acceleration (a)
The mass (m) is 45 kg, and the acceleration (a) is 1.5 m/s². Plug these values into the formula:
F = 45 kg × 1.5 m/s²
F = 67.5 N
So, the force created by the person is 67.5 Newtons.
Answer:
0.025 A
Explanation:
A = 50 cm^2 = 50 x 10^-4 m^2
B2 = 6 T, B1 = 2 T
db = 6 - 2 = 4 T
dt = 2 s
R = 0.4 ohm
Let i be the magnitude of induced current and e be the induced emf.
According to the Faraday's law of electromagnetic induction
e = dФ / dt
e = A dB / dt
e = 50 x 10^-4 x 4 / 2 = 0.01 V
i = e / R = 0.01 / 0.4 = 0.025 A
