If the same pressure is exerted over a greater area will more of less force result? Group of answer choices :
Zigmanuir [339]

Answer:

More force

Explanation:

Pressure and force are related by the equation:

p=\frac{F}{A}

where

p is the pressure

F is the force

A is the area

We can re-arrange the equation as

F=pA

In this problem, the pressure is kept the same (p' = p) while the area is increased. As we can see from the previous equation, the force applied is directly proportional to the area: therefore, a greater area means also a greater force.

A car has a momentum of -456 kg*m/s. What direction is it moving?
Solnce55 [7]

backward movement

because momentum = mass × speed

And mass must be in positive value..

so negative value is speed

which moving backward..

A 22.0-kg child is riding a playground merrygo-round that is rotating at 40.0 rev/min. What centripetal force is exerted if he i
Tems11 [23]

Answer:

F=480.491 N

Explanation:

Given that

mass ,m = 22 kg

Angular speed ω = 40 rev/min

\omega=\dfrac{2\pi \times 40}{60}\ rad/s

ω =4.18 rad/s

The radius  r= 1.25 m

We know that centripetal force is given as

F=m ω² r

Now by putting the values in the above equation we get

F=22\times 4.18^2\times 1.25\ N

F=480.491 N

Therefore the centripetal force on the child will be 480.491 N.
