Answer:
FG and FP
Explanation:
Gravitational Force(FG) because the box is being pulled down and a resistance force pushing up because he is pushing(FP) up on the box.
I hope this helps!
Answer:
The answer is "Option C".
Explanation:
Computation modeling is used as the software for math, physics, or software engineering in the simulation and study of complicated processes. The software framework incorporates many parameters, that characterize the model under study. It is a computer program, in which the mathematical formula is generated by computers and research complex systems.
Answer:
The potential energy of the ball is 784 joules. And the kinetic energy of it is 392 while falling halfway down.
Explanation:
PE = mass (2kg) * Gravitational acceleration (9.8 m/s^2)* height (40 meters)
KE = 1/2 mass (1 kg) * velocity^2 (19.8)
Answer:
because they are same and their properties
For a pipe open at both ends, fund frequency (Fo) given byFo = v /2L
v = velocity of sound = 340 m/s (at about 20ºC)
Fo = 340/2*5.34 = 31.8 Hz
While for the one closed at one end and open at the other end...
For a pipe open at one end, fund frequency (Fo) given byFo = v/4L
Fo = 340/4*5.34= 15.9 Hz
