How to convert units of volume in physics?

Units of volume in physics can be converted different ways depending what you have. But the most important thing to remember is that Liters is not the standard unit. the standard unit is meters cubed (m^3). if you think about the volume of a cube is length * width * height. these are length dimensions resulting in meters cubed. You can convert liters to meters cubed by understanding that 1 mililiter = 1 cm^3.

therefore it is possible to convert liters to mililiters. That value is the same as the cm^3 value. from there you can say that (1 meter)^3 = (100 cm)^3. You have to see that the cubed on this is outside the parenthesis. this means that you do not use 100 as the conversion but 100^3 (which is the same as using 1,000,000) so there is 1,000,000 cm^3 per 1 m^3. hope this helps cuz I do not understand the question

A rigid tank whose volume is unknown is divided into two parts by a partition. One side of the tank contains an ideal gas at 927

Marianna [84]

Answer:

The final temperature will be 3600 K.

Explanation:

Side 1

T=927°C

T=1200 K

Lets take volume of one side is V then the volume of other side will be 2V. The final volume of system will become 3 V.

The system is closed so the mass of system will remain constant .

We know that for ideal gas P V = m R T

The final pressure is same as initial pressure so we can say that

$\dfrac{T_i}{V_i}=\dfrac{T_f}{V_f}$

$\dfrac{1200}{V}=\dfrac{T_f}{2V+V}$

$T_f=3600\ K$

So the final temperature will be 3600 K.

If a soundproof door is almost shut but still leaves a small opening, what wave phenomenon is responsible for someone being able

lana66690 [7]

The phenomenon which is responsible for this effect is called diffraction.

Diffraction is the ability of a wave to propagate when it meets an obstacle or a slit. When the wave encounters the obstacle or the slit, it 'bends' around it and it continues propagate beyond it. A classical example of this phenomenon is when a sound wave propagates through a wall where there is a small aperture (as in the example of this problem)

In billiards, the 0.165 kg cue ball is hit toward the 0.155 kg eight ball, which is stationary. The cue ball travels at 5.8 m/s

Damm [24]

Answer:

another ball velocity = 3.92 m/s and with 30° clockwise from initial direction

Explanation:

given data

mass m1 = 0.165 kg

mass m2 = 0.155 kg

before collision velocity v1 = 5.8 m/s

before collision velocity v2 = 0

angle = 35.0° from initial direction

after collision 1st ball velocity v3 = 3.2 m/s

to find out

after collision another ball velocity v4

solution

we consider here ball move in x axis and after collision 1st ball move upside of x axis with angle 35 degree and other ball move downside with x axis with angle θ

so from conservation of momentum we say

m1v1 = m1v3cos35 + m2v4cosθ with x axis .............1

m1v3sin35 = m2v4sinθ with y axis .............2

so from 1 equation

0.165 × 5.8 = 0.165(3.2)cos35 + 0.155(v4)cosθ

v4 cosθ = 3.38 .................3

form 2 equation

0.165(3.2)sin35 = 0.155(v4)sinθ

v4 sinθ = 1.95 ......................4

so magnitude of another ball velocity is square and adding equation 3 and 4

another ball velocity = √(3.39²+1.96²)

another ball velocity = 3.92 m/s

and direction is tanθ = 1.96/3.39

θ = 30° clockwise from initial direction

If two bodies weighing 10 kg and 20 kg respectively are standing at the

kvv77 [185]

Answer:

potential energy = mgh , where m is mass of body , g is acceleration due to gravity and h is given height

since both of the body are at same height above the ground , so the body having greater mass will have more potential energy

that is 20 kg body will have higher P.E
