A diffraction grating is illuminated simultaneously with red light of wavelength 670 nm and light of an unknown wavelength. The

fifth-order maximum of the unknown wavelength exactly overlaps the third-order maximum of the red light.
What is the unknown wavelength? (in nm)

Answer:

dsin∅ = m× λ

so, dsin∅red = 3(670nm)

also, dsin∅? =5λ?

however ,if they overlap then dsin∅red = dsin∅?

3(670nm) /5 =402nm

∴λ = 402nm

A city located on the coast of North America has warmer winters and cooler summers than a city at the same elevation and latitud
Vesna [10]

I don't like any of those choices. But if you absolutely have to pick your answer
from this list, then it has to be 'D'.

The ocean is an enormous storage vessel for heat.  It gets heat from the air in
the Summer ... which somewhat cools places near the coast ... and it releases
heat into the air during the Winter ... which warms places near the coast.

So I guess it's true that ocean surfaces change temperature more slowly than
land surfaces do, and they influence the land nearby in the process. But this
ignores the reason for the slow changes in ocean surface temperature. It's a
lot like saying that the loud noise produced by a race car is the result of the
car's ability to appear in a far different location after a short time.

What is the approximate weight of a 20-kg cannonball on Earth? 2 N 20 N 196 N 1,960 N
Margaret [11]
Since weight is the force an object is exerting on another object, and the formula to calculate force is Force = Mass * Acceleration, the answer to your question is 196 N, since the mass of the cannonball times Earth's gravitational pull equals 196 N.

Which object will experience the greatest acceleration ?
tekilochka [14]

Answer:

Y will experience the most acceleration

Explanation:

Because using F=ma, you can rearrange the formula to show that acceleration equals force over mass. You then do the calculations for each of the objects, and y will be your answer.
