Kinetic energy = 1/2 mv²
so, you will have to do it for every single one of them if you want steps.
Kinetic Energy = For A, 202500J
For B, 90000J
For C, 168750J
For D, 75000J
From the above we an say that kinetic energy is highest in option A.
In case, there are no steps needed, just by the values we are able to understand the answer as in Option A, eventhough the mass is the same, higher the velocity or speed, higher the kinetic energy
When you grow your brain grows its very complicated you cant just GET smart you have to learn easy stuff like 2+2 to 83x17 more you grow more your brain grows more stuff you learn but to get smarter read more do math more JUST DO EVERYTHING MORE to grow your brain and fill in your brain
Answer:
They would decline
Explanation:
They would either migrate, or die.
Answer:
Zero Acceleration.
Explanation:
If an object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations. Thus, the net force is zero and the acceleration is 0 m/s/s. Objects at equilibrium must have an acceleration of 0 m/s/s.
Answer:
The force is 
Explanation:
We can apply the following expression
To find the area of rectangular tent wall:
Now to find the force:
