Read the sentences below, and indicate which accurately describe the effects of Earth's rotation and the angle of the Sun. Select all that apply. View Available Hint(s) Select all that apply. The tilt of Earth and the latitude of a city affect the degree and amount of direct sunlight that the location receives at the winter solstice. From the spring equinox until the fall equinox, the Sun shines continually at the North Pole (for 6 months). However, temperatures during this time never get very warm due to the high angle of the Sun striking Earth at the poles. The circumference of Earth at the equator is 24,900 miles. Based on this, a person at the equator is rotating 1040 miles per hour. (Round to the nearest tens digit.) You see the Sun directly overhead in Anchorage, Alaska, at 60° N on the summer solstice. This indicates that Earth is tilted at a 50° angle.

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
