Answer:
14000 J / 0.40 J/s = 35 000 s or about 9.75 hrs
It helps the cell by making sure everything gets circulated throughout the cell.
a because of the following rate I do not now I saw it on the other one
Answer:
0.24 km
Explanation:
Total time taken = 25 + 10 + 15 = 50 mins
Total distance covered = 1.0 km( initial distance ) + 0.76 km( final distance ) = 1.76 km
therefore the displacement of the individual = 1 - 0.76 = 0.24 km
displacement is the difference between final distance and initial distance covered by an individual and it is a vector quantity
Option A, B, C, D
Child on a swing, Pendulum, Bow and Arrow, Roller Coaster is mechanical energy being conserved
<u>Explanation:</u>
Mechanical energy is the total of kinetic and potential energy in a thing that is employed to do a job. A conservative force is a power like gravitation or a spring that “bends backward” energy that was conveyed by producing activity. The friction and other non conservative forces, nevertheless, conservation of mechanical energy is surely conserved.
When one stretches or contracts an elastic object, one does act fronting the spring force, and that task finishes up saved as elastic potential energy. Constantly shifting things up and down, producing variations in potential energy is termed as gravitational potential energy.
Here Child on a swing, Pendulum, Bow & Arrow, Roller Coaster in all there is the continuous conversion between gravitational/elastic potential energy and kinetic energy.
