Question

For each of the following scenarios, indicate whether the oscillation period of the block becomes shorter, longer or remains unchanged. Note: you must clearly mark your answer (for example, highlight it in red) from the multiple-choice list below and you must provide an explanation of your answer to receive credit. Review: course textbook (section 9.1).
a. The mass of the block is reduced.
i. Shorter
ii. Longer
iii. Unchanged
Explanation:

b. The spring – mass device is transported to the Moon, where the acceleration due to gravity is weaker.
i. Shorter
ii. Longer
iii. Unchanged
Explanation:

c. The stiffness of the spring is reduced (i.e., the spring constant is lowered).
i. Shorter
ii. Longer
iii. Unchanged
Explanation:

d. The amplitude of the oscillation is increased (i.e., the distance the mass travels up and down is increased).
i. Shorter
ii. Longer
iii. Unchanged
Explanation:

Answer 1

All explanations on the base of formula for period os spring pendulum

T=2πsqrt(m/k)

(a) m↓=>T↓
i. Shorter

(b) iii. Unchanged

(c) k↑↓ => T
ii. Longer

(d) iii. Unchanged
