Answer:
Momentum of the object = 15 kg.m/s
Explanation:
Given
mass, m = 5 kg
speed, v = 3 m/s
momentum, p = ?
We know that the momentum is given by the equation:
p = mv
= 5 kg x 3 m/s
= 15 kg.m/s
Answer = A) fossil fuels
B and C are renewable types of energy
D is a type of fossil fuel, just like oil
Answer:
L = 2774.4 
Explanation:
Using the formula
L = mvr
Where L is angular momentum
m is mass
v is velocity
r is radius
m= 51kg , v=17m/s , r=3.2m
L = 51×17×3.2
L = 2774.4
Answer:
No
Explanation:
Loudness describes how people perceive sound (see loudness). ... If people could hear equally well at all frequencies, the contour lines would be flat because the same measured sound intensity would be perceived to be equally loud regardless of the sound frequency. In fact, people do not hear as well at low frequencies.
