Answer:
a = v^2/r centripetal acceleration
v = (a * r)^1/2 = (42 * .23)^1/2 = 3.1 m/s
Waves can be described using a number of different characteristics of a wave. Wavelength and frequency are two such characteristics. The relationship between wavelength and frequency is that the frequency of a wave multiplied by its wavelength gives the speed of the wave
Answer:

Explanation:
Let assume that gases inside bulbs behave as an ideal gas and have the same temperature. Then, conditions of gases before and after valve opened are now modelled:
Bulb A (2 L, 2 atm) - Before opening:

Bulb B (3 L, 4 atm) - Before opening:

Bulbs A & B (5 L) - After opening:

After some algebraic manipulation, a formula for final pressure is derived:

And final pressure is obtained:


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
