Charina says that when waves interact with an object, they will interfere with the object and that when waves interact with other waves, they will reflect off each other. Do you agree with her? Why or why not?

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.

Describe how the motion of a spring being pushed forward and backward is similar to the motion of air particles in a sound wave.

Which type of energy is transferred by convection currents?
