Answer:
I believe A would be the best answer
Explanation:
Cell transport means things entering and leaving the cell, this would be controlled by the cell membrane
Waste excretion is controlled by the vacuole
Energy production is the mitochondria (the mitochondria is the power house of the cell)
Life functions include cellular reproduction and the nucleus contains the genetic information to do this
Answer:
Correct option C. "The two objects stick together"
Explanation:
There are two types of collision. First one is elastic collision and other one is inelastic.
In inelastic collision, the linear momentum before and after the collision is same but the kinetic energy after the collision is not constant. It is used in the form of heat, light etc.
For an inelastic collision, two objects after collision sticks together and move with a common speed. It is one of the important factor for inelastic collision.
Answer:
Tortoise has the greatest momentum
Explanation:
Momentum of tourtise (p)=mass×velocity
=275×0.55
=151.25 kgm/s
Answer:
1.15 rad/s²
Explanation:
given,
angular speed of turntable = 45 rpm
=
=
time, t = 4.10 s
initial angular speed = 0 rad/s
angular acceleration.
Hence, the angular acceleration of the turntable is 1.15 rad/s²
