Conduction. is a transfer of energy by direct contact
There is no direct relationship between power
and either of those quantities.
The formula for momentum is p=mv (mass multiplied by velocity), so in this problem, p=50(.5)=25=p or in other words, momentum.
Answer:
I think it's option D
Explanation:
I think it's option D but not so sure
.Answer:
491.4 nm
Explanation:
The distance between central and first maxima is,

And the distance between screen abnd grating is,

Now the angle can be find as,

Now the grating distance is,

Now with m=1 condition will become,

So,

Therefore the wavelength of laser light is 491.4 nm.
