Answer:

Momentum is conserved in all three physical directions at the same time.

Explanation:

There is a peculiarity, however, in that momentum is a vector, involving both the direction and the magnitude of motion, so that the momenta of objects going in opposite directions can cancel to yield an overall sum of zero.

How much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m^2 exerts a pres

andriy [413]

Answer:

Weight, W = 125 N

Explanation:

Pressure, P = 5 Pa

Area, A = 25 m²

We need to find how much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m² exerts a pressure of 5 Pa. So,

Pressure = force/area

So,

$F=P\times A\\\\F=5\times 25\\F=125\ N$

So, the weight of the man is 125 N.
