An automotive research facility is testing a new design on bumpers to determine the force at which it will break. the formula for force is f = 1 2 m v 2 where m is the mass (weight) and v is the velocity (speed)what is the effect on the force if the velocity changes from 5 miles per hour to 10 miles per hour?

The force increases by 4 units when velocity changes from 5 miles per hour to 10 miles per hour.

Explanation: The force is given by the formula:

Force when v = 5 miles per hour

Force when v = 10 miles per hour

Taking ratio of and

Hence, the force is increased by 4 units when velocity changes from 5 miles per hour to 10 miles per hour.

c, 1a hope this

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
