Answer:

500m/s

Explanation:

From the question we are given the following;

mass per unit length = 4.80 x10^-3 kg/m

Tension T = 1200N

Speed of the wave is expressed as;

v = √T/m

v = √1200/0.0048

v = √250,000

v = 500m/s

Hence the speed at which the wave travels on this string is 500m/s

Calculate the work efecttuated, when the force is 300 N, and the distance is 300 meters.
Alexxx [7]

Hello!

Use the formula:

W = Fd

Replacing:

W = 300 N * 300 m

Resolving:

W = 90000 J

The work is <u>90000 Joules.</u>

An electric bell is placed inside a transparent glass jar. The bell can be turned on and off using a switch on the outside of th
Art [367]
The answer is :  We’ll see the bell move, but we won’t hear it ring.  This is    because light can travel through vacuum but sound cannot.  Sound waves are vibrations of particles in any media, so sound requires a medium to travel, and it cannot travel in a vacuum as there is no particles to vibrate.
