The car's kinetic energy is
KE = (1/2) (mass) (speed)² .
We notice that the speed is squared in the formula for KE,
so the KE varies as the square of the speed.
If the speed changes from 20mph to 60mph, it has tripled.
So the KE increases by a factor of (3²) = 9 times the original KE.
The tiny holes on the surface of plants are what the plant use to store sunlight and food/water
All chemical processes are accompanied by energy changes. When a reaction proceeds, it either releases energy to, or absorbs energy from, its surroundings. In thermodynamics, these two types of reactions are classified as exothermic or endothermic, respectively.
Answer:
TEJ as this is a thing you wont get
Answer:
The answer is
<h2>15.0 J</h2>
Explanation:
To calculate the work done by a body we use the formula
<h3>work done = force × distance</h3>
From the question
force = 10 N
distance covered = 1.5 m
So the work done is
work done = 10 × 1.5
We have the final answer as
<h3>15.0 J</h3>
Hope this helps you
