By what factor should the length of a simple pendulum be changed in order to triple the period of vibration?

kenny6666 [7]

Answer:

increased by 9 times

Explanation:

As the period of a simple pendulum is defined as the following formula

$T = 2\pi\sqrt{\frac{L}{g}}$

where L is the length of the pendulum and g is the constant gravitational acceleration. Since L is under a square root, if you want to triple the period of vibration, L must be increased by 9 times so that $\sqrt{9} = 3$

A space traveler discovers that her weight on a new planet is 192 newtons. Her mass is 68 kilograms. What is the gravitational a

alina1380 [7]

Answer:

g ≈ 2.82 m/s^2

Explanation:

By W = mg,

W = weight (in newtons)

m = mass (in kg)

g = gravitational acceleration (in m/s^2)

$192 = 68g$

$g = 2.82352941176 m/s^2$

g ≈ 2.82 m/s^2
