Describe what happens to pressure as the force exerted on a given area increases.

Physics
1 answer:
Goryan [66]3 years ago

That's the definition of pressure ... force on a given area.

So when that force increases, it's an increase in pressure.

How can you find the net force if two forces act in opposite directions?
Tresset [83]

Then the magnitude of the net force is the difference between the two forces,
and its direction is the same as the direction of the greater one.

If Frequency F, velocity v, and density D are considered fundamental units, the dimensional formula for momentum will be :
gizmo_the_mogwai [7]

Let's see

Momentum be P

\\ \rm\Rrightarrow P=[Frequency]^a[velocity]^b[Density]^c

\\ \rm\Rrightarrow [P]=[F]^a[v]^b[D]^c

\\ \rm\Rrightarrow [M^1L^1T^{-1}]=[T^{-1}]^a[L^1T^{-1}]^b[M^1L^{-3}]^c

\\ \rm\Rrightarrow MLT^{-1}=T^{-a}L^bT^{-b}M^cL^{-3c}

\\ \rm\Rrightarrow MLT^{-1}=T^{-a-b}L^{b-3c}M^c

On comaparing

  • c=1

So

  • b-3c=1
  • b-3=1
  • b=1+3
  • b=4

and

  • -a-b=-1
  • -a-4=-1
  • -a=-1+4=3
  • a=-3

So the unit is

  • DV⁴/F³

What is a horizontal segment meaning on a position vs. time graph?
sergeinik [125]

The velocity of the object is zero (the object is at rest)

Explanation:

A position vs time graph represents the motion of an object; in particular:

  • The position of the object x(t) is represented on the y-axis
  • The time t is represented on the x-axis

For a position-time graph, the slope of the graph is given by

m=\frac{\Delta x}{\Delta t}

where

\Delta x is the change in position

\Delta t is the change in time

However, we see that this is equivalent to the definition of velocity:

v=\frac{\Delta x}{\Delta t}

Therefore, the slope of  a position-time graph is equivalent to the velocity of the object.

And so, a horizontal segment on a position vs time graph means that the object has zero velocity (because the slope is zero).
