Answer:
Fg = gravitational force. When a force is applied on the body, not only the applied force is acting there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force. Therefore, the net force formula is given by, FNet = Fa + Fg + Ff + FN.
Answer:
21st of December
Explanation:
In the northern hemisphere there occurs winter solstice on 21st of December. During this time, the tilt of the earth in the northern hemisphere is away from the sun. So the places near and at Antarctica, there will be sunlight for about 24 hours and the sun does not set on this particular day.
And, on the other hand, the places near the Arctic circle experiences darkness for about 24 hours and the sun does not rise on this specific day.
One watt is defined as the energy consumption rate of one joule per second. 1W = 1J / 1s. One watt is also defined as the current flow of one ampere with voltage of one volt.
Effect of balanced force'
*net force is zero
*no change in shape
*no change in size
*equal and opposite force
