A. 37 A/m
B. None of these
C. 3.7 A/m
D. 370 A/m
Explanation
Magnetization (M) is the product of the magnetic field intensity (H) and the magnetic susceptibility (χ):
M = χH
Given:
χ = 3.7 × 10^-3
H = 10^4 A/m
M = (3.7 × 10^-3) × (10^4 A/m)
= 37 A/m

کسی سیارے کے بڑے پیمانے پر اور قطر زمین سے دوگنا ہوتا ہے۔ پینڈولم سیارے کے دوچار ہونے کی مدت ہوگی (اگر یہ زمین پر دوسرا لاکٹ ہے)؟
A. None of these
B. 2√2 seconds
C. 1√2 seconds
D. 1/2 second
Explanation
The formula for the period of a pendulum is T = 2π√(l/g) , where l is the length of the pendulum and g is the acceleration due to gravity. Since the mass and diameter are doubled , the acceleration due to gravity (g) on the planet will be half that of Earth. Therefore, the new period of oscillation will be √2 times the period on Earth, meaning if it was a second's pendulum on Earth, it will be 2√2 seconds on the planet.
