If there is no air resistance, the value would still be the same. So therefore, the answer is 39.7 N.
Supposing that there is an air resistance of 19.8 N.With a 19.8 N air resistance: ∑F = 39.7 N - 19.8 N = 19.9 N would be the net force. The important point here is that the force of gravity equivalent the weight of the object.
Answer:true
Explanation:
It takes the moon approximately a month to complete an orbit round the earth
Answer: D) It should be handled in a fume hood, away from open flames.
If the circuit is open, then there will be no light or sound. No current will flow and no air will move.
