The velocity of a wave is

a. its direction and speed.

b. the distance between two wave crests.

c. the time required for a wave to move one wavelength.

d. half the vertical distance between a crest and a trough divided by the frequency.

A beam of light is propagating in the x direction. The electric-field vector (a) can oscillate in any arbitrary direction in space. (b) must oscillate in the z direction (c) must oscillate in the yz plane (d) must oscillate in the x direction.

a ray of light emerging from glass into air is incident at the critical angle of the glass block what is the angle of refraction in the air

What will occur when the trough of Wave A overlaps the trough of Wave B? A: Destructive interference will occur, causing the new wave to have more energy than Wave A or Wave B.

Materials that can be broken down and recycled by bacteria and other decomposers are classified as 1. Renewable 2. Non-renewable 3. Biodegradable 4. Non-biodegradable

When the change in momentum occurs over an extended period of time, the force of impact is:?

A moving object has a kinetic energy of 150 j and a momentum with a magnitude of 30.0 kg•m/s. determine the mass and speed of the object

How does changing depth affect water pressure

The mass of a rigid rod is 0.60 kg and its length is 39.0 cm. Calculate the moment of inertia (in kg · m2) for the rod if it is pivoted about an axis through the center of mass of the rod. (Assume the axis is perpendicular to the rod.

Does a rolling basketball have kinetic energy

Noah Formula is in an airplane which is flying at constant speed in a circular course of radius 6500 m, circling O'Hare's airplane prior to landing. Noah observed that the plane completes each round trip in 345 seconds (5 minutes & 45 seconds).
