The controlled release of nuclear energy in a reactor is accomplished by controlling fission without a chain reaction.
Answer:
height is the answer i'm pretty sure.
Explanation:
Given: Wavelength λ = 686 nm convert to meter λ = 6.86 x 10⁻⁷ m
Velocity of light c = 3.00 x 10⁸ m/s
Required: Frequency f = ?
Formula: f = c/λ
f = (3.00 x 10⁸ m/s)/(6.86 x 10⁻⁷ m)
f = 4.37 x 10¹⁴ Hz or
f = 437 Terahertz
For uniform acceleration (or deceleration in this case), you use the formula:
Vf = Vi + at
Vi = 22 m/s
Vf = 0 (coming to a stop)
t = 5 sec
Plugging everything into the formula gives you:
0 = 22 + 5a
-22 = 5a
a = -22/5 or -4.4 m/s^2
Hope this helps!
