Answer:
Which of the following was not a reaction to John Brown's execution because of his failed raid on Harper's Ferry ???????
Explanation:
Answer: 430 nm.
Explanation:
The relation of wavelength and frequency is:
Formula used : 
where,
= frequency =
= wavelength = ?
c = speed of light = 
Now put all the given values in this formula, we get
Thus the wavelength (in nm) of the blue light emitted by a mercury lamp is 430 nm.
Electrical forces travel far through the universe
Torque = r x F
|F| = mg = 60 * 10 N = 600 N ( assuming g ~ 10m/s^2)
distance of fulcrum = torque / Force = 90/600 m = .15 m.
Answer:
The answer to your question is W = 3695464.4 J
Explanation:
Mechanical work is the force applied to an object multiply by the distance this object move as a consequence of the force.
Formula
Work = W (J)
Force = F (N)
distance = d (m)
W = F x d
Substitution
F = 6818.2 N
d = 542 m
W = 6818.2 x 542
Simplification and result
W = 3695464.4 J
