A bike travels at a constant speed of 3.1 m/s for 6 s. how far does it go?

IgorC [24]

Ah for this problem you are thinking quite a bit hard on. The problem is actually simpler than it looks. The problem states that a bike travels at a constant speed of 3.1 m/s for 6 s and asks how far will it go?. To figure this out you simply need to take 3.1 times 6 s because every second the bike travels 3.1 m. So the answer to this problem would be 18.6 m

A model car is 29 cm in length. How many inches long is it?

Delvig [45]

1 cm = 0.39 in.

29 cm = 0.39 * 29

29 cm = 11.41 in.

An ideal gas in a sealed container has an initial volume of 2.50 L. At constant pressure, it is cooled to 21.00 ∘C, where its fi

Answer: The initial temperature of the system comes out to be 147 °C

Explanation:

To calculate the initial temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=2.50L\\T_1=?K\\V_2=1.75L\\T_2=25^oC=(25+273)K=294K$

Putting values in above equation, we get:

$\frac{2.50L}{T_1}=\frac{1.75L}{294K}\\\\T_1=420K$

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

$T(K)=T(^oC)+273$

$420=T(^oC)+273\\T(^oC)=147^oC$

Hence, the initial temperature of the system comes out to be 147 °C

I believe the correct answer from the choices listed above is the second option. The statement that would best explain the sequence of events would be that the victim shot himself in the mouth. Hope this answers the question. Have a nice day.
