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.

How does the electric potential energy between two charged particles change if one particle is reduced by a factor of 3? a. increased by a factor of 3 b. it is decreased by a factor of 9 c. it is reduced by a factor of 3 d. it is increased by a factor of 9

Amajor impediment to wide acceptance of electric vehicles even on the part of people who use their cars almost exclusively for commuting is the inability to use their electric vehicles for occasional extended trips. in an attempt to make purchasing electric vehicles more attractive to commuters, one electric vehicle producer is planning to offer customers three days free rental of a conventional car for every 1,000 miles that they drive their electric vehicle. which of the following, if true, most threatens the plan's prospects for success? (a) many electric vehicles that are used for commercial purposes are not needed for extended trips. (b) because a majority of commuters drive at least 100 miles a week, the cost to the producer of making good the offer would add considerably to the already high price of electric vehicles. (c) the relatively long time it takes to recharge the battery of an electric vehicle can easily be fitted into the regular patterns of car use characteristic of commuters. (d) although electric vehicles are essentially emission-free in actual use, generating the electricity necessary for charging an electric vehicle's battery can burden the environment. (e) some family vehicles are used primarily not for commuting but for making short local trips, such as to do errands.

A: all waves on the electromagnetic spectrum travel at the same speed in a vacuum. the speed of these waves in a vacuum is 3x108 m/s. as the wavelength of a wave doubles, how does the speed and frequency of the wave change?
