hi I have a calculus question it says Two forces of 70 N act on an object. The forces form an angle of 57degree between them. Calculates the resultant force and the force that must be applied to the object to create balance. (Shows diagram of force vectors.)

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
