Applying diffraction equations;
d = 0.01/Number of lines; where 0.01 m = 1 cm, and d = spacing between lines
Therefore,
d = 0.01/2000 = 5*10^-6 m
Additionally,
d*Sin x = m*y; where x = Angle, m = order = 1, y = wavelength = 520 nm =520*10^-9 m
Substituting;
Sin x = my/d = (1*520*10^-9)/(5*10^-6) = 0.1040
x = Sin ^-1(0.104) = 5.97°
Therefore, first-order maximum for 520 nm will be 5.97°.
Answer:
m = 0.0125 kg
Explanation:
Let us apply the formula for the speed of a wave on a string that is under tension:
where F = tension force
μ = mass per unit length
Mass per unit length is given as:
μ = m / l
where m = mass of the string
l = length of the string
This implies that:
Let us make mass, m, the subject of the formula:
From the question:
F = 20 N
l = 4.50 m
v = 85 m/s
Therefore:
Protons and neutrons have similar mass
Electrons are smaller then a proton or a neutron
Answer: 2.67 m/s^2
Explanation:
Centripetal acceleration is defined as v^2/r; in this case, it's 2^2/1.5, which is 2.67.
An object with non-zero mass (even negligible mass is non-zero) will never reach the speed of light. Due to relativistic effects, each "unit" of acceleration becomes less effective at increasing your velocity (relative to some other object, of course) as your relative velocity approaches the speed of light.
And even if there was a way, If you would accelerate to the 99,99% of the speed light in just 1 second, you would experience a G-force of aprox. 30,600,000 g's which is enough to kill you in a few seconds
