Answer:
Parachute exerts a force of 619.2 N upward
The net force is 86.4 N acting downward
Explanation:
As the gravitational acceleration g = 9.8 m/s2, the parachute help reduces the net acceleration to 1.2m/s. So it must exerted an upward acceleration on the skydiver of
9.8 - 1.2 = 8.6 m/s2
Since the skydiver mass is 72 kg, we can use Newton's 2nd law to calculate the force that causes this acceleration of 8.6
F = ma = 8.6*72 = 619.2 N acting upward
The net force is also the product of net acceleration and mass
= 1.2 * 72 = 86.4 N acting downward
The layers of the fossil the oldest is usual the bottom layer,and the top layer is the newest layer
Using current technology, useful parallax measurements can only be found for stars up to about 340 light years (100 parsecs) away.
Yes that answer is correct because sometimes tides cause waves to happen
Answer:
force is the answer because force is pushing the item
