The volume of a gas varies directly with its temperature and inversely with the pressure. If the volume of a certain gas is 15 c

vladimir2022 [97]

Answer:

Therefore the volume of the gas is 32 cubic feet.

Step-by-step explanation:

Given that,

The volume of a gas varies directly with its temperature and inversely with the pressure.

$V\propto \frac{T}{P}$

V= Volume of the gas at constant mass

T= Temperature at constant mass

P= pressure at constant mass

$\frac{V_1}{V_2}=\frac{\frac{T_1}{T_2}}{\frac{P_1}{P_2}}$

$\therefore \frac{V_1}{V_2}=\frac{T_1P_2}{T_2P_1}$ .

Given that,

At constant mass, the volume of a certain gas is 15 cubic feet and a pressure of 40 pound per square inch at a temperature 300 k.

$V_1$ =15 cubic feet, $P_1$ =40 pound per square inch and $T_1$ = 300 K

$V_2=?$ , $P_2$ =20 pound per square inch and $T_2$ = 320k

$\therefore \frac{V_1}{V_2}=\frac{T_1P_2}{T_2P_1}$ .

Plugging all values

$\frac{15}{V_2}=\frac{300\times 20}{320\times 40}$

$\Rightarrow V_2=\frac{15\times 320\times 40}{300\times 20}{}$

$\Rightarrow V_2=32$ cubic feet

Therefore the volume of the gas is 32 cubic feet.

If a football player passes a football from 4 feet off the ground with an initial velocity of 36 feet per second, how long will

Sergeeva-Olga [200]

Answer:

A. 0.72

Step-by-step explanation:

When the ball hits the ground, h = 0.

0 = -16t² + 6t + 4

0 = 8t² − 3t − 2

Solve with quadratic formula:

t = [ 3 ± √(9 − 4(8)(-2)) ] / 16

t = (3 ± √73) / 16

t = 0.72

Anna35 [415]

Answer:

x = 32 words

Step-by-step explanation:

Okay...let's get solving! :D Firstly, we

let the word list be x and convert the long paragraph into an equation that we can use.

one-fourth = 1/4

Memroized = 8 words

$x * \frac{1}{4} = 8$

Thus, we solve the equation.

x = 32 words

Please help with this problem

aleksley [76]

Your answer would be 19 and 20.

To solve this, you need to first think about perfect square numbers, and which ones are the closest to 375. This is because perfect squares will always get square rooted back to a whole number, so therefore the ones around 375 would be the closest whole numbers.

Now, 400 is one of the easier to remember square numbers. It is 20 squared. 375 is pretty close to 400, however its slightly lower. So now, let's look at the closest perfect square that's less than 400: 19^2, or 361.

375 is between 361 and 400, so therefore it is between the square root of 361 and 400, or 19 and 20.

Good luck!
