Answer:
The net force on the car is 2560 N.
Explanation:
According to work energy theorem, the amount of work done is equal to the change of kinetic energy by an object. If '
' be the work done on an object to change its kinetic energy from an initial value '
' to the final value '
', then mathematically,
where '
' is the mass of the object and '
' and '
' be the initial and final velocity of the object respectively. If '
' be the net force applied on the car, as per given problem, and '
' is the displacement occurs then we can write,
Given, 
.
Equating equations (I) and (II),
<span>A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. A good example of this is a balloon. Air inside a balloon is compressed by the balloon's rubber walls. The air pushes back so that the inward and outward pressing forces are balanced. When the nozzle is released, air escapes through it and the balloon is propelled in the opposite direction.</span>
If a cell grows beyond a certain size, materials will not be able to pass through the membrane fast enough to accommodate the inside of the cell. So when the cell reaches a size too large, it will divide into smaller cells in order to maintain a surface are/volume ratio that is more favorable to the functioning of the cell. Therefore, cells remain small in order to survive.
If the powerboat is operating at night, the light that must be shown is: <span>A white masthead light
Since dark colors dominated the surrounding during the night time, a white masthead light will provide the exact contrast for the color in the surrounding, which makes it easily identified from far away.</span>
