<span>As in all the solids, their atoms are arrange in certain intermolecular distances. When the pressure in the solid, it changes this intermolecular distances which causes selectively changes all those effects which are associated with the interactions between molecules. Pressure changes the phonon frequencies, changes in phonon line shape in the solid. This is also responsible for change in melting and boiling points. The pressure may also cause for phase transition in many solids.</span>

A suspended object A is attracted to a charged object B, can one conclude that A is charged? Explain

irinina [24]

Explanation:

In my view, when the Object A is attracted to a Charged object B. Object B should be Negatively or Positively charged. So Object B should be the Opposite charged according to the Object B

Example =

If Object B is Negatively Charged, the Object A should be Positively Charged

If the Object B is Positively Charged, the Object A should be Negatively Charged

Sometimes it can Mix as a Neutral as well

a foul ball is hit into the stands at a baseball game. the ball rises to a height of 38 meters and is caught on its way down by

lisov135 [29]

The velocity of the ball when it was caught is 12.52 m/s.

<em>"Your question is not complete it seems to be missing the following, information"</em>,

find the velocity of the ball when it was caught.

The given parameters;

maximum height above the ground reached by the ball, H = 38 m

height above the ground where the ball was caught, h = 30 m

The height traveled by the ball when it was caught is calculated as follows;

y = H - h

y = 38 - 30 = 8 m

The velocity of the ball when it was caught is calculated as;

$v_f^2 = v_0 + 2gh\\\\v_f^2 = 0 + (2\times 9.8 \times 8)\\\\v_f^2 = 156.8\\\\v_f = \sqrt{156.8} \\\\v_f = 12.52 \ m/s$

Thus, the velocity of the ball when it was caught is 12.52 m/s.

Two objects, with different masses, have a gravitational potential energy of 100 J each; they are released from rest and fall to

Fittoniya [83]

The statement can't be true. Objects with different masses held at the same height don't have the same gravitational potential energy.
