Ojectile is launched on the earth with a certain ini- tial velocity and moves without air resistance. another projectile is launched with the same initial velocity on the moon, where the acceleration due to gravity is one- sixth as large. how does the range of the projectile on the moon compare with that of the projectile on the earth? (a) it is one-sixth as large. (b) it is the same. (c) it is ! 6 times larger. (d) it is 6 times larger. (e) it is 36 times larger.

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation
