Answer:
v₁
Explanation:
A crew member is walking on a tugboat that is pulling a barge. The tugboat is moving at a constant speed upstream in a river that has a constant downstream current. The velocity of the crew member with respect to the tugboat is v₁. What is the velocity of the crew member with respect to the barge?
velocity is the change in displacement per time.
the velocity of the crew member with respect to the barge is v₁ since the barge is moving in the velocity of tugboat
The power equals energy divided by the time
P=E/t
P=1200/60
P=20W
Hope you get it!
Answer:
They two waves has the same amplitude and frequency but different wavelengths.
Explanation: comparing the wave equation above with the general wave equation
y(x,t) = Asin(2Πft + 2Πx/¶)
Let ¶ be the wavelength
A is the amplitude
f is the frequency
t is the time
They two waves has the same amplitude and frequency but different wavelengths.
