Explanation:
Answer:
Part a)

part b)

Part c)

Part d)
here since wave is moving in negative direction so the sign of
must be positive
Explanation:
As we know that the speed of wave in string is given by

so we have


now we have


now we have
Part a)
= amplitude of wave

part b)

here we know that


so we have


Part c)

Part d)
here since wave is moving in negative direction so the sign of
must be positive
Answer:
A fire hose must be able to shoot water to the top of a building 35.0 m tall ... Water enters this hose at a steady rate of 0.500 m3/s and shoots out of a round nozzle. ... I know that Flow rate=0.500 m3/s=A*V. I know the pressure needed to ... The first equation has no potential while the second has no kinetic.
Explanation:
Answer:
1.2 s
Explanation:
The period of a pendulum is the time it takes to complete one cycle, as in move and return to its initial state, for example going from one side to the other and coming back. If this pendulum goes from one side to the other in 0.6 s, it will take it the doble of that time to perform a cycle, and that is the period
T = 2 * 0.6 s = 1.2 s
