He has 1 1/30 gallons, or 31/30 gallons, you can find this by setting all the fractions to a common denominator and adding them
The wave height is equal to twice the amplitude of the wave.
The wave height of a wave of given wave with amplitude, period and wavelength is equal to twice the amplitude of the wave.
The amplitude of a wave is the maximum displacement of the wave, starting from the zero position of the wave. The wave height measures twice the maximum displacement of the wave.
Thus, we can conclude that the wave height is equal to twice the amplitude of the wave.

Answer:
Explanation:
The acceleration due to gravity on the surface of the Earth is given by:
where
G is the gravitational constant
M is the mass of the Earth
R is the radius of the Earth
Here we want to find the new Earth radius R' for which the gravitational acceleration at the surface, g', would be 3 times the current value of g:
So we would have
Solving the equation for R', we find
Answer:
The change in internal energy of the system = -772kJ
Explanation:
Given :
Heat lost by the system , a = -266KJ
Workdone by the system, W = -506KJ
The first law of thermodynamics states that:
Change in internal energy = q + w
Substituting values into the equation
Change in internal energy = (-266KJ) + (-506KJ)
Change in internal energy = -722KJ
