Waves become larger and bend towards land (refract)when motion within the wave is circular the wave length is less than twice the sea bed depth the wave length is less than half the sea bed depth cliffs are absent

Which of the following are true about constellations? Constellations move to new locations throughout the year. As the Earth revolves around the sun, different parts of the universe become visible Some constellations can not be seen in winter because they become darker. The constellation Orion is only visible at certain times of the year. When the Earth orbits the Sun, the Earth is facing different directions as it moves.

4. Provide evidence from the experiment that an object's motion depends on the forces acting on it and its mass.

The period and frequency of a wave are directly related. OTrue False

70. II A cubical box 20 cm on a side is constructed from 1.2-cm- thick concrete panels. A 100 W lightbulb is sealed inside the box. What is the air temperature inside the box when the light is on if the surrounding air temperature is $20^{\circ }C$

Strain and deformation are basically the same thing because it pertains to length. True False

33. II A $10m\times 14m$ house is built on a 12-cm-thick concrete slab. What is the heat-loss rate through the slab if the ground tempera- ture is $5^{\circ }C$ while the interior of the house is $22^{\circ }C$ ?

A sprinter runs at a constant speed of 8.0 meters per second on a circular track that has a radius of 40.0 meters. Part 1 What is the centripetal acceleration of the sprinter? $0.20m/s^{2}$ $0.40m/s^{2}$ $1.6m/s^{2}$ $5.0m/s^{2}$

Part 2 If the radius of the circular track is halved, what happens to the magnitude of centripetal acceleration of the sprinter? It doubles. It quadruples. It is reduced four times. It remains the same.

When bounce passing where should the ball bounce? Closer to the passer who threw the ball Closer to the person receiving the ball In the middle of both people Doesn't Matter
