Answer:
The ability of gases to be forced or squeezed into smaller volumes is called compressibility
It would fall at about/ around 96 mph
The resultant of the acceleration can be found using:
a = √(ax² + ay²)
a = √(1.5² + 3.7²)
a = 3.99 m/s²
v = u + at, u = 0
v = 3.99 x 6.4
v = 25.5 m/s
Answer:
88.2J
Explanation:
Given parameters:
Mass of book = 3kg
Height of shelf = 3m
Unknown:
Potential energy = ?
Solution:
The potential energy of a body is the energy due to the position of that body.
It can be mathematically calculated as;
P.E = mgh
m is the mass of the body
g is the acceleration due to gravity = 9.8m/s²
h is the height
Now insert the parameters and solve;
P.E = 3 x 9.8 x 3 = 88.2J
