Answer:
5.99 J
Explanation:
A ball is thrown 6m above the ground.
Its total energy at that point is 12 J.
The energy of the ball is given by :
E = mgh
Where
m is the mass of the ball
Let E' is the total energy of the ball at a halfway point of motion. h' = 3 m
So,
So, the required energy is 5.99 J.
Pressure exerted by means of an Earth's atmosphere.
<u>Explanation:</u>
Atmospheric pressure is also termed as barometric pressure, that is the pressure exist in the Earth's atmosphere, in other words it is the pressure wielded by the atmosphere's weight.
1 atmosphere = 760 mm Hg
Atmospheric pressure could be measured using the equation,
Atmospheric pressure = Mercury's density × acceleration through gravity × the height of mercury column.
It can be measured or given in terms of Pa, torr. atm, psi, mm Hg and so on.
