Answer:
As the skydiver falls to the Earth, she experiences positive acceleration only due to gravity.
Explanation:
As the skydiver falls to the Earth, she experiences friction in the form of air resistance which tries to slow her down and is proportional to the her velocity. So it cannot have a positive acceleration as it acts in opposite direction to slow her down.
Inertia during skydiving is experienced when we open an parachute, the parachute slows down the speed of are descent hence changing our inertia of motion with a velocity.
Only the Earth's, gravitational field has an positive acceleration as it pulls us towards the Earth, hence increasing our velocity.
All except C, feelings are not physical.
Answer:
A motorcycle moves 5km in 10 minutes(10×60s=600 seconds)
A motorcycle moves 5/600 km in 1 second.
A motorcycle moves 1/120 km in 1 second.( 5/600 = 1/120)
Two or more elements that are chemically combined
Answer:
3,333.33 /sec
Explanation:
frequency = 1/period
= 1/0.0003 = 3,333.33 /sec
