Einstein's famous equation states that the energy in an object at rest equals its mass times the square of the speed of light. (The speed of light is 300,000,000 m/s.) Complete the skeleton code below so that it: * Accepts the mass of an object (remember to convert the input string to a number, in this case, a float). * Calculate the energy, e * Prints e

Aball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and passes the top of the window 0.20 s later. the window is 2.0 m high from top to bottom. what was the ball's initial velocity? the unit vector j^ is directed upward. how far is the bottom of the window from the launch position? how high does the ball rise above the launch position?

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.
