Answer: 6,000 pounds ( lbs)
1 ton equals 2,000 pounds 3 X 2,000lbs = 6,000lbs
If the object doesn't move you have done no work.
Answer:
0 Nm
Explanation:
Torque is the cross product of the radius vector and the force vector.
τ = r × F
In other words, the magnitude of the torque is equal to the magnitude of the radius times the magnitude of the force times the sine of the angle between them.
τ = rF sin θ
Since F₃ is parallel to the radius vector, θ = 0, so τ = 0.
Answer: 0.4m
Explanation:
Given that:
Amplitude of wave = 2.0 m
Wavelength (λ)= ?
Frequency F = 500Hz
Speed V = 200 m/s
The wavelength is measured in metres, and represented by the symbol λ.
So, apply the formula:
Wavespeed V= Frequency F xwavelength λ
200m/s = 500Hz x λ
λ = 200m/s / 500Hz
λ = 0.4m
Thus, the wavelength is 0.4 metres
