Will give brainless) - Which of the following is true about solar radiation? 1. The incoming radiation getting into our atmosphere is not equal to what is leaving our atmosphere

2. The solar radiation enters our atmos as short wave radiation--high energy

3. Once the solar energy is in our atmos, the it turns into a longer wave energy that has less energy, than what cam into our atmos.

4. Our atmos is trapping some solar energy causing global temps to increase

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
