Answer:

Desired\ effect=1312.5\ W

The net effect on the laboratory is cooling of the space.

Explanation:

Given:

power used by the air conditioner, P_i=750\ W

coefficient of performance, COP=1.75

We know that:

\rm COP=\frac{desired\ effect}{Power\ consumed}

<u>Therefore the cooling power capacity:</u>

\rm Desired\ effect=COP\times power\ consumend

Desired\ effect=1.75\times750

Desired\ effect=1312.5\ W

The net effect on the laboratory is cooling of the space.

If the frequency of wave is 400 Hz and its wavelength is 2.5 m,<br> what is the velocity?
BigorU [14]
1000 m/s

You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.

A satellite was in two separate crashes. In both crashes, the satellite had the same mass. Engineers want to know about the spee
irina1246 [14]

Answer & Explanation:

Crashing into the asteroid would cause the satellite to slow down, stop, or reverse direction, because it is a force in the opposite direction to the satellite's motion. Whichever crash was a stronger force would cause it to change motion more. It takes a stronger force to change the velocity of a more massive object.
