If you travel 40 miles east and then turn around and drive 12 miles west, the displacement is?

AVprozaik [17]

To find how far east we drove (This is the displacement), we simple subtract 12 from 40.
An easy way to do this in your head is to round 12 down to 10, subtract 10 from 40, then subtract the remaining 2. This should result in an answer showing that you drove 28 miles east.

When the temperature of an ideal gas is increased, the pressure also ________

kherson [118]

<h2>Answer: increases </h2><h2 />

Explanation:

The expression for an Ideal Gas is:

$P.V=n.R.T$

Where:

$P$ is the pressure of the gas

$V$ is the volume of the gas

$n$ the number of moles of gas

$R$ is the gas constant

$T$ is the absolute temperature of the gas

As we can see, there is a <u>direct proportional relation between the temperature and the pressure</u>, which means that if the temperature increases the pressure of the gas increases as well.

However, it is important to note this is fulfilled if and only<u> if the volume of the container where the ideal gas is, remains constant.</u>

An amount of work W is done on an object of mass m initially at rest, and as result it winds up moving at speed v. Suppose inste

sesenic [268]

Answer:

Explanation:

Given

W amount of work is done on the system such that it acquires v velocity after operation(initial velocity)

According to work energy theorem work done by all the forces is equal to change in kinetic energy of object

$W=\frac{1}{2}mv^2---1$

where m=mass of object

v=velocity of object

When the object is already have velocity v then the final speed is given by work energy theorem

$W=\frac{1}{2}mv_f^2-\frac{1}{2}mv^2-----2$

From 1 and 2 we get

$\frac{1}{2}mv^2=\frac{1}{2}mv_f^2-\frac{1}{2}mv^2$

$2\times \frac{1}{2}mv^2=\frac{1}{2}mv_f^2$

$v_f^2=2v^2$

$v_f=\sqrt{2}v$

Marus traveled on a motorcylce distance of 1,298meters north to get to the nearest shopping center. He then turned back south an

andrew-mc [135]

Answer:

48 meters north

Explanation:

If you measure the distance between the point Marus started and the point where they stopped after traveling 1,250 meters back south, you get 48 meters. To make this a displacement quantity, you add 'north' to the end and get 48 meters north, considering this was the initial direction of the motorcycle.
