No, he did not perform any work. Work is when you’re using energy which results in a force. Even though he was tired and sweaty, he did not move the boulder. So therefore he did not perform any work.
Electrical power is defined as
P = I * V
I = 3 amperes
V = 240 volts
Power = 3 * 240
Power = 720 Watts. Answer
Answer:
The amplitude of the wing tip's motion is 1.6 mm.
Explanation:
Given that,
Beat = 250 /s
Speed = 2.5 m/s
We need to calculate the amplitude of the wing tip's motion
Using the equation for the maximum velocity


Where,
v = speed
f = frequency
A = amplitude
Put the value into the formula



Hence, The amplitude of the wing tip's motion is 1.6 mm.
Answer:
As the pressure inside the pressure cooker increases as it is heated, the temperature also increases.
Explanation:
A pressure cooker contains water and steam in equilibrium at a pressure greater than atmospheric pressure.
According to the ideal gas law, as the pressure increases, the temperature also increases.
As the pressure inside the pressure cooker increases as it is heated, the temperature also increases.
