Answer: Compression ratio

Explanation:

Let's begin by explaining that in a combustion chamber there are pistons that move up and down within cylinders. If we take as an example one cylinder, we will have the following:

-The bottom dead center (BDC) is when the volume in the combustion chamber is the greatest, because the piston is exactly at the bottom of the cylinder.

- The top dead center (TDC) is  when the volume in the combustion chamber is the lowest, because the piston is at the top (the highest point) inside the cylinder.

Now, the ratio between these two volumes is the Compression ratio.

When the flashlight is in the air and the refracted ray enters the water, how does the angle of refraction compare with the angl
tigry1 [53]

Answer:

The refracted angle will be less than the angle of incidence and the speed of light is slower in the new medium (which is water) and is closer to the normal.

Try remembering this by using FST SFA (Fast Sofa)

                                             Fast -> Slow = Towards the normal

                                             Slow -> Fast = Away from normal

A sample of a gas in a rigid container has an initial pressure of 5 atm at a temperature of 254.5 k. The temperature is decrease
skelet666 [1.2K]

The gas is in a rigid container: this means that its volume remains constant. Therefore, we can use Gay-Lussac law, which states that for a gas at constant volume, the pressure is directly proportional to the temperature. The law can be written as follows:

\frac{P_1}{T_1} = \frac{P_2}{T_2}

Where P1=5 atm is the initial pressure, T1=254.5 K is the initial temperature, P2 is the new pressure and T2=101.8 K is the new temperature. Re-arranging the equation and using the data of the problem, we can find P2:

P_2 = T_2 \frac{P_1}{T_1}=(101.8 K) \frac{5 atm}{254.5 K}=2 atm

So, the new pressure is 2 atm.

If 3600 j of work is done in 3.0 s what is the power<br>0.00083W<br>1200W<br>3600W<br>11000W
Viktor [21]

Answer:

1200 W

Explanation:

Power is given by the ratio between work done and time taken:

P=\frac{W}{t}

where W is the work done and t the time taken.

In this problem, W = 3600 J and t = 3.0 s. Therefore, the power in this exercise is

P=\frac{3600 J}{3.0 s}=1200 W
