Electrons have a negative charge, so if you give away electrons, you give away negative charge, thus ending with a positive charge.
Answer:
Explanation:
When the pendulum falls freely the net acceleration due to gravity is zero.
As we know that the time period of simple pendulum is inversely proportional to the square root of acceleration due to gravity, thus the time period becomes infinity.
Answer:
Correct Answer is positive force → balanced force → negative force
Explanation:
When Diego gives a big lift to the piano with the help of pulley system that time, initially piano moves upward so positive force acts on it.
Later, Piano stops, in this condition balanced force act on it since force applied by Diego is balanced by gravitational force of earth.
After some time piano starts falling in this condition negative force will act on the piano. In this condition, gravitational force will acts on piano in downward direction.
