B.
Both recognized that the elements have repeating properties but Mendeleev realized that there are elements yet to be discovered while Newlands tried to fit the known elements together.
Answer:
water can be used as displacement to calculate the volume of a solid object.
Because the forces are not balanced the pin will fall down and go backwards and the force of the bowling ball will keep going after acting upon the non active pin
The correct option is;
The voltages become negative instead of positive and keep the same magnitudes
Explanation: Here we have that there is a change in direction from positive to negative with the direction pointing to opposite of the initial direction whereby the field strength does not change due to the reversal of the. Therefore the voltage becomes negative instead of negative while keeping the the magnitude.
That is there is a electric field reversal or a change electric field direction.
