When you stand at rest on a floor, the number of vertical forces acting on you is?

Two forces.

Explanation:

If I am standing on the floor which is at rest then there will be two vertical forces act on me. One is in downward direction which is gravitational force and one is in upward direction which is normal to the gravitational force.

In the given below figure there is 2 forces mg in downward direction and normal force N in upward direction and these forces are equal.

N=mg

Here, m is the mass and g is acceleration due to gravity.

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?
