Answer:
0.12
Explanation:
The acceleration due to gravity of a planet with mass M and radius R is given as:
g = (G*M) / R²
Where G is gravitational constant.
The mass of the planet M = 3 times the mass of earth = 3 * 5.972 * 10^24 kg
The radius of the planet R = 5 times the radius of earth = 5 * 6.371 * 10^6 m
Therefore:
g(planet) = (6.67 * 10^(-11) * 3 * 5.972 * 10^24) / (5 * 6.371 * 10^6)²
g(planet) = 1.18 m/s²
Therefore ratio of acceleration due to gravity on the surface of the planet, g(planet) to acceleration due to gravity on the surface of the planet, g(earth) is:
g(planet)/g(earth) = 1.18/9.8 = 0.12
It expands and pushes the crack further aprt

b. 
Explanation:
The frequency of a harmonic oscillator is given by the following formula:
----------------- equation (1)
a.
In order to double the frequency of this oscillator:
ω' = 2ω
m' = ?
Therefore,
using equation (1):
a.
In order to triple the frequency of this oscillator:
ω' = 3ω
m' = ?
Therefore,
using equation (1):
