Answer:
From the formula of force:

since AB and k are constants:

x is a constant of proportionality
• when force is 4N, separation distance is 1

therefore, equation becomes

when r is doubled, r becomes 2. find F:

The formula for the pendulum experiment is based on the assumption that the amplitude is small so that the angle is approximately equal to the Sine of the angle.
The answer is A. The outer lines change as it moves
Answer:
111,000 Pa
Explanation:
P = Patm + ρgh
122,000 Pa = Patm + (921 kg/m³) (9.8 m/s²) (1.22 m)
Patm = 111,000 Pa
