Answer:
P=9.58 W
Explanation:
According to Newton's second law, and assuming friction force as zero:
The acceleration is given by:
So the force exerted by the motor is:
The work done by the motor is given by:
And finally, the power is given by:
Answer:
6
Explanation:
Given that
dsinθ = mλ,
now, if sinθ = 1, then
m = d / λ, where
m = order of interference
d = distance between the slits
λ = wavelength of light
this is the formula we would use to solve the question
d = 1 / 320 lines/mm
d = 1 / 320*10^3
d = 3.125*10^-6 m
At λ = 551 nm, we have
m = 3.125*10^-6 / 551*10^-9
m = 5.67
5.67 ~ 6
thus, we can say that the orders of visible wavelength 551 nm, can produce is 6
The atomic mass of neon is 20 amu.
20 amu = 10 p + 10 n
Neon has an atomic number , Z = 10 and contains 10 protons and 10 neutrons. It can completely filled electron shells and it is thus a noble gas.<span> i.e. </span><span>the number of 10 protons in the nucleus which defines the element. </span>
I think if I was a researcher I would review my work or the sources I use, True
