If an atom gains electrons, it develops a negative charge equal to the number of electrons gained.
So the net charge on the copper atom which gained 2 electrons will be -2.
To ensure a steady flight, the standard golf ball has nearly 400 indentations <span>or “dimples” on its surface. The correct option among all the options that are given in the question is the second option or option "B". The other choices are incorrect. I hope that this is the answer that has actually come to your help.</span>
This being a perfect collision means no energy is lost during the collision. Because this question asks for speed and not velocity, the speed will be the same because the final energy is the same. The speed after the collision would therefore be 1.27 m/s.
Answer:
At light intensity I = 3, is P a maximum
Explanation:
Given:
now differentiating the above equation with respect to Intensity 'I' we get
or
or
or
Now for the maxima 
thus,
or
or
or
or
I = 3
thus, <u>for the value of intensity I = 3, the P is maximum</u>
at I = 3
or
or
