What is the velocity of a fly with a mass of approximately 6.85 times 10 to the negative 6 slugs if it has a kinetic energy of 5

vodka [1.7K]

Velocity of the fly: 1318 m/s

Explanation:

The kinetic energy of an object is the energy possessed by the object due to its motion. It can be calculated as

$K=\frac{1}{2}mv^2$

where

m is the mass of the object

v is its speed

For the fly in this problem, we have

$m=6.85\cdot 10^{-6} kg$ is the mass

K = 5.95 J is the kinetic energy

Solving for v, we find its velocity:

$v=\sqrt{\frac{2K}{m}}=\sqrt{\frac{2(5.95)}{(6.85\cdot 10^{-6})}}=1318 m/s$

Although the green light flashes first, you are moving away from it, so it illuminates you at the same moment as the red light.

A green laser is frequently used by amateur astronomers because its visible beam may be used to point out stars and galaxies because it penetrates the atmosphere so far. Red lasers are less adaptable than green lasers. Each wave or component of light in a laser has been precisely aligned to form a single, strong beam.

Green DPSS lasers are the most popular and first emerged on the market about 2000. (also called diode-pumped solid-state frequency-doubled, DPSSFD). Due to the rarity of laser diodes in this wavelength region, they are more complicated than regular red laser pointers.

Green lasers have been used in head-mounted displays and laser guides for defense and security purposes. Amateur astronomers can also direct and track stars using green laser guides.

A wave has a wavelength of 8 mm and a frequency of 14 Hertz what is its speed?

iren [92.7K]

To find the speed you multiply the wavelength and the frequency together.

wavelength = 8mm = $8x10^{-3}$ m = 0.008 m
frequency = 14 Hz

speed = 0.008m * 14 Hz = 0.112 m/s
