Answer:w=mxg
2x10 =20 N
Explanation:force acting downwards is mg mass into gravitional feild
Answer:
The population of the mice will decrease to the faster, stronger, and smarter mice because the weaker will die because of natural selection.
Explanation:
Answer:
a. 
b. 
Explanation:
Using the triangle theorem both triangle the woman makes between the light so the rate of change of length can use geometry first

Solve to find the rate relation


Now the rate of the change rate


Finally the rate of her shadow moving


So the best conductor for electricity is silver.
However because silver is so expensive we use copper which is the next best conductor
The picture shows it has a real life something to display conservation of energy with kinetic energy and potential energy.
Five sentences are for potential and kinetic energy. Potential energy is to energy an object when it stores. Kinetic energy is something to motion. When the potential energy is slows down the potential energy it might be increases. As from the object when the speeds up and it is decreases to potential energy.
Kinetic energy is to calculated by KE= mass×velocity²/2 as a fraction.
Potential energy is to calculated by PE= mass×g×height.
And the another picture it has a <span>energy, kinetic energy, mechanical energy, conservation of energy.
