<span>82.0 kg
I am going to assume that there is a typo for the number of joules of energy. Doing a google search for this exact question showed this question multiple times with a value of 4942 joules which makes sense given how close the "o" key is to the "9" key. Because of this, I will assume that the correct value for the number of joules is 4942. With that in mind, here's the solution.
The gravitational potential energy is expressed as the mass multiplied by the height, multiplied by the local gravitational acceleration. So:
E = MHA
Solving for M, the substituting the known values and calculating gives:
E = MHA
E/(HA) = M
4942/(6.15*9.8) = M
4942/60.27 = M
81.99767712 = M
Rounding to 3 significant figures gives 82.0 kg</span>
Answer:
50 Hz
Explanation:
The frequency of a wave is given by
where
v is the speed of the wave
is the wavelength
In this problem,
v = 60 m/s
So the frequency is
The greatest point for kinetic is at the bottom and in the middle it is in half and at the top it is at the highest in potential energy.
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation<span> illustrates that momentum is directly </span>proportional<span> to an object's mass and directly </span>proportional<span> to the object's velocity.</span>
The portable tank should be connected to earth to neutralise rhe charges to prevent sudden discharge which may cause sparks and lead to fire.
