Answer:
kinetic mechanical energy
Answer:
65m
Explanation:
Twelve waves pass a dock in 3.60 If the waves are traveling at 19.5 m/s , what is the wavelength of the waves?
Velocity of a wave is expressed as;
V = frequency × wavelength
Given
Velocity = 19.5m/s
Frequency is the number of oscillations completed in 1sec, hence
Frequency= 3.6/12
Frequency = 0.3
Wavelength = vel/freq
Wavelength = 19.5/0.3
Wavelength = 65m
Answer:
the mass of the truck is 2 kg.
Explanation:
Given;
mass of the car, m₁ = 3 kg
initial velocity of the car, u₁ = 40 m/s
initial velocity of the truck, u₂ = 60 m/s
let the mass of the truck = m₂
Apply the principle of conservation of linear momemtum;
m₁u₁ = m₂u₂
m₂ = (m₁u₁) / u₂
m₂ = (3 x 40) / (60)
m₂ = 2 kg
Therefore, the mass of the truck is 2 kg.
Weight. As a scientific term Weight is referred to as the force that Earth and objects have with each other. Your weight can be different on other planets.
