Answer: average speed of the ball would be 48 mph
Explanation:
because all you have to do is multiply 24 x .5 and that gives you your answer
The answer is 2) 1.0c. Light will always propagate through a vacuum at the speed of light “c”; even when moving at a significant fraction of the speed of light, observers will still measure this as the speed of light and the difference is resultant of time dilation.
Answer: It would be 75
Explanation: If your pushing on the floor at a rate of 5 for 15 seconds you would multiply the numbers and get 75
Altitude is the height of something or the point of sea level or ground level.
hope i helped!!
The second ionization energy is the energy required to remove the <u>second </u>electron after a <u>valence</u> one has been removed.
<h3><u>Explanation:</u></h3>
For an element, the first ionization energy is defined as the amount of energy required to remove one electron from the outermost valence shell of a neutral atom. Removing one electron increases the number of protons, making it a 1+ ion.
The nucleus (protons) has more bonding to the electrons with negative charge and thus more energy is required if another electron needs to be removed. This higher energy required to remove second electron from a 1+ ion (after the first one has been removed) is termed as the second ionization energy. Second ionization energy leads to formation of a 2+ ion. Similarly, third ionization energy is higher than second ionization energy.
