Challenge: a hammer is dropped on planet x. if the hammer has a mass of 3 kg and a weight of 9 n, what is the gravitational acceleration of planet x and is it more or less than that of earth?

Suppose that instead of being inclined to Earth's orbit around the Sun, the Moon's orbit was in the same plane as Earth's orbit around the Sun. (Click "Show Moon with flat orbit" to see this situation.

Which order shows decreasing wavelength? gamma → ultraviolet → infrared → radio infrared → gamma → radio → ultraviolet radio → infrared → ultraviolet → gamma ultraviolet → radio → infrared → gamma

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. What is the BEST explanation of the relationship between wavelength and wave energy? A) Wave energy is related only to frequency, not wavelength.

Friends Burt and Ernie stand at opposite ends of a uniform log that is floating in a lake. The log is 3.0 m long and has mass 20.0 kg. Burt has mass 30.0 kg; Ernie has mass 40.0 kg.

Use the periodic table to complete this equation that represents the process of nuclear fusion. Superscript 14 Subscript 7 Baseline N + Superscript 1 Subscript 1 Baseline H yields Superscript A Subscript B Baseline C

Josh rolled a bowling ball down a lane in 2.5 seconds. The ball travelled at a constant acceleration of 1.8 m/s/s down the lane and was traveling at a speed of 7.6 m/s by the time it reached the pins at the end of the lane.

How many meters of the rock wall eroded between 1910 and 1927?

As air temperatures increase, evaporation increases. Warmer temperatures also increase the capacity to absorb water vapor. More water vapor in the atmosphere accelerates the greenhouse effect.
