Answer: 25 joules
Explanation:
Recall that kinetic energy is the energy possessed by a moving object.
So, kinetic energy = 1/2 X Mass X Velocity^2
Mass = 0.5kg
Velocity = 10m/s^2
= 1/2 x 0.5kg x 10^2
= 0.5 x 0.5 x 100
= 25 Joules
Thus, the kinetic energy of the moving ball is 25 joules
I believe it would be manual labor. During the Industrial Age of Employment, most people would have to do repetitive jobs, or manual labor. Design, engineer, and knowledge broker were not common during this time.
If the paramecium was not able to contract its contractile vacuole, it would be in danger of bursting. The cell would not be able to hold too much water. This would happen faster if the paramecium was in water with a low salt concentration because there is more water and less salt, so the water would accumulate faster.
Mammals
just like us humans. have backbone, lungs, and reproduce on land
