Fast need answers <br>Find the amount of force if the body has pressure of 178 Pa on 18 mm²​
guajiro [1.7K]

Answer:

Force = 3.204Newton

Explanation:

Given the following data;

Pressure = 178

Area = 18 mm² to meter = 18/1000 = 0.018 m²

To find the force;

Force = pressure * area

Force = 178 * 0.018

Force = 3.204 Newton.

If an object has a large momentum, how easy is it to stop, and why?
podryga [215]
It is dificult to stop an object with a lot of momentum becuase of inertia with means that a moving object will want to keep moving and a stationary object wil want to stay stationary and the larger the momentum of the moving object the harder it will be to stop

How far must you be from a 110 W speaker to have an intensity of 0.0439 W/m^2? (Treat the speaker as a point source.)
Lina20 [59]

Answer:

d=14.12m

Explanation:

Assume a point sound source that emits a sound power<em> P </em>(in W) evenly in all directions of space. Let us also assume that the medium does not absorb this sound power when it passes through it. At a distance<em> d </em>from the source this power will have been evenly distributed over the surface of a sphere of radius <em>d</em>. Therefore, the acoustic intensity I at distance d will be worth:

I=\frac{P}{4\pi d^{2}}

This is the expression of the so-called<em> law of the square of distance: "the intensity is inversely proportional to the square of the distance to the source (considered punctual)".</em>

So

I=0.0439 \frac{W}{ m^{2}}

P=110W

d=\sqrt { \frac{P}{4 \pi\\I}

d=\sqrt{ \frac{110}{ 4\pi (0,0439)} }

d=\sqrt{{199.39}

d=14.12m
