Water waves in ripple tank is an example of trasverse wave. It means that the water molecules vibrate perpendicular to the direction of the movement of wave.
For example, if the water wave is moving from left to right then the water molecules vibrate up and down.
Sound waves produced by the motor is an example of longitudinal wave. It means air particles vibrate parallel to the direction of movement of wave.
For example, if sound wave is moving from left to right, the particle will also vibrate left to right.

Answer:
Emf induced in the loop is 0.02V
Explanation:
To get the emf of induced loop, we have to use faraday's law
ε = - dΦ/dt
To get the flux, we use;
Φ = BA cos(θ)
B = The uniform magnetic field
A = Area of rectangular loop
θ = angle between magnetic field and normal to the plane of loop
substitute the flux equation (Φ) into the faraday's equation
we have ε = - d(BA cos(θ)) / dt
ε = BA sinθ dθ/dt
from the question;B = 0.18T, A=0.15m2, θ = π/2 ,dθ/dt = 0.75rad/s
Our equation will now look like this;
ε = (0.18T) (0.15m2) (sin(π/2)) (0.75rad/s)
ε = 0.02V
Average speed = (distance rolled) / (time to roll the distance)
Average speed = (32 meters) / (0.8 sec)
Average speed = (32/0.8) (meters/sec)
<em>Average speed = 40 m/s .</em>

I don't know. That's just a hair under 90 miles per hour. Is this reasonable for a bowling ball ? Does anybody roll a bowling ball as fast as a major league pitcher pitches a hardball ? ?
