Answer:
C.
The particles in longitudinal waves travel parallel to the direction of the wave, whereas the particles in transverse waves travel perpendicular to the direction of the wave.
Explanation:
Longitudinal waves are waves that propagates energy from their source by movement of particles in a direction parallel to the wave motion.
Transverse waves produce oscillations that are perpendicular to the direction of propagation.
- Examples of longitudinal waves are sound waves, seismic p-waves
- Examples of transverse waves are electromagnetic waves
A wave is a disturbance that transmits energy from one point to another.

Set the proportion up 37.50/105.50 = 41/x and solve for x
Work = Force * distance
He's going up an incline but pushing parallel to the ground. Draw out a diagram to show what's going on. )
Work = force* distance*Cos(incline angle)
60 N force * 10 meters * cos(30)
= 519.61 J
Explanation:
When a charged particle describes a circular path in a uniform magnetic field, the charged particle experiences a magnetic force towards the center of circular path, according to Fleming's left hand rule. Therefore the magnetic force and velocity (tangent to circular path) are perpendicular to each other during the circular motion. As the direction of displacement, is the direction of velocity, hence force and displacement are perpendicular to each other.
Therefore work done by magnetic force,
W=Fscos90=0
