Color wheel

What is the frequency of a wave if the speed is 4300 m/s and the wavelength is 32 m? Formula? Solution?

The formula 1 car collided with the wheel at 130km / h and stopped in 0.14 seconds. Calculate the acceleration of the car and the driver in a collision. assume that the movement is steadily slowing down.

Why is the moon more important than the sun for causing earth's ocean tides?

Light does bend in a gravitational field. Why is this bending not taken into consideration by surveyors who use laser beams as straight lines?

Visible light with a wavelength of 480 nm appears as what color?

A 2.0-kilogram mass is located 3.0 meters above the surface of Earth. What is the magnitude of Earth's gravitational field strength at this location? (1) 4.9 N/kg (3) 9.8 N/kg (2) 2.0 N/kg (4) 20. N/kg

How long did the astronauts stay on the moon?

Brenda is standing on the beach; the sea is choppy. she observes that the crests of distant waves appear not only smaller, but also closer together than do the crests of waves nearer the beach. this example illustrates a depth cue known as:

If two waves in the same space interfere completely destructively, which of the following occurs? A. The amplitude decreases. B. The amplitude increases. C. The wave speed increases. D. The wave speed decreases.

An electric force exists between which pair of objects? Check all that apply. A) a neutral object and a negative object two negative objects B) a neutral object and a positive object C) two positive objects D) a negative object and a positive object
