The <u>speed of sound wave</u> in <u>water</u> is much more greater than its <u>speed in air</u>, so when the sound wave passes from sea water to air, then it's <u>speed decreases</u>.

A 29.0 kg beam is attached to a wall with a hi.nge while its far end is supported by a cable such that the beam is horizontal.
Elanso [62]

The tension in the cable is 169.43 N and the vertical component of the force exerted by the hi.nge on the beam is 114.77 N.

<h3>Tension in the cable</h3>

Apply the principle of moment and calculate the tension in the cable;

Clockwise torque = TL sinθ

Anticlockwise torque = ¹/₂WL

TL sinθ  =  ¹/₂WL

T sinθ  =  ¹/₂W

T = (W)/(2 sinθ)

T = (29 x 9.8)/(2 x sin57)

T = 169.43 N

<h3>Vertical component of the force</h3>

T + F = W

F = W - T

F = (9.8 x 29) - 169.43

F = 114.77 N

Thus, the tension in the cable is 169.43 N and the vertical component of the force exerted by the hi.nge on the beam is 114.77 N.

Which example best illustrates the transfer of energy between two waves?
FromTheMoon [43]

Answer:

A) A buoy rises in the water as a boat speeds past.

Explanation:

The passing boat transfers energy in the form of a wave. Other options illustrate other physics concepts like gravity (falling egg) or Newton's law (for every action, there is an equal and opposite reaction).

A car is raised on a lift at a service station (so it has some amount of gravitational potential energy relative to the ground).
kenny6666 [7]

Answer:Twice

Explanation:

It is given that car is raised on a lift with respect to ground.

Suppose car is raised by a height of h m from ground having mass m so gain in Potential Energy by car is

Gain in P.E._1=m\times g\times h

Now if it were raised twice as high,i.e. 2 h height from ground then gain in Gravitational Potential Energy

=m\times g\times 2h

P.E._2=2m\cdot g\cdot h

It is clear that P.E._2=2\cdot P.E._1

Thus in second case gain in Potential Energy is twice as compared to first case
