While he is lifting the dumbell as the definition of work done = moving a mass through a distance = F x d
Answer:
Coring is a defect in an alloy (e.g., a copper nickel alloy) that occurs when a heated alloy is cooled too fast for diffusion to occur.
Explanation:
Answer:
10,000kgm/s
Explanation:
Since we not told what to look for, we can as well find the momentum of the car.
momentum = mas * velocity
Given
Mass of the car = 2000kg
velocity = 5m/s
Substitute into the formula
Momentum = 2000 * 5
Momentum = 10000kgm/s
Hence the momentum of the car is 10,000kgm/s
We can write 75 = 25 x 3
and √75 = <span>√ (25 x 3) = </span>√25 x <span>√3
Now we know that square root of 25 is 5 a 5x5 = 25
so we can express this in the form of 5</span><span>√3.</span>
The separation between the lines of the grating is 13.33μm.
<h3>What is diffraction grating?</h3>
The diffraction grating is the continuous lines with very minute slits or grating space in mm. It divides light composed of various wavelengths into light components by particular wavelength.
dsinθ = nλ
Substitute n =3, λ =490 x 10⁻⁹ m and angle θ =6.33°, we get
d = [3 x 490 x 10⁻⁹ /sin 6.33°]
d = 13.33 x 10⁻⁶ m
Thus, the separation between the lines of the grating is 13.33μm.
