<h3><u>Answer;</u></h3>
M.A = 4.25
<h3><u>Explanation;</u></h3>
Mechanical advantage is the ratio of the force required to do something in comparison to the actual force required using a simple machine.
It is the ratio of output force to the input force.
M.A = Output Force/ Input Force
Out put force 85 Kg = 850 N
Input force = 200 N
Therefore;
M.A = 850 N/200 N
= 4.25
Answer:
Mid ocean ridge is formed when old oceanic crust is forced under continental plates.
Explanation:
Ocean basin is a kind of land surface that is present under an ocean and below the water.
Ocean basin contain continental shelf,mid ocean ridge that is found on the sea floor.
The size of ocean basin is equal to the size of an ocean and is found below the ocean.
When, water covers the earth's crust region in the distant past,ocean basin formation occurs.This prcess require long time as spreading of sea floor and tectonic plates takes place.
Ex-Atlantic Ocean basin is formed over million years that is present in the European Continent.
To compute for the heat,

needed to be absorbed or released, we need

where

is the mass of the alligator,

is the change in temperature, and

is the specific heat of the alligator's body. Plugging in all the information we have,

Recall that 1 Watt = 1 J/s, thus time needed to absorb radiation from the sun is

That means it takes 4250 seconds for the alligator to warm up to be able to absorb the radiation from the sun.
Answer: 4250 seconds
