Gas always expands or contracts to exactly fill whatever you put it in.
So to measure the volume of a gas, just measure the volume of the jar, the tank, the bottle, the can, or the balloon that the gas is in.
Answer:
Velocity is a vector (it has magnitude and direction), so the overall velocity of an object can be found with vector addition of the x and y components: v2 = vx2 + vy2. The units to express the horizontal and vertical distances are meters (m).
Answer:
Young's modulus.
Explanation:
Let's see the definition of the three moduli announced.
First, the bulk modulus (K) is used to measure the resistance to compression of a fluid by the next expression:
<em>where V: is the volume and P: is the pressure of the substance. </em>
Second, the shear modulus (G) measure the stiffness of solids by the next equation:
<em>where F: is the force onto the material, A: is the material area, l: is the length and Δx: is the transverse displacement.</em>
And third, the Young's modulus (E) relates the stress and the strain in a material by the following equation:
<em>where σ: is the uniaxial stress, and ε: is the strain.</em>
Therefore, evaluating the definitions seen above, Young's modulus is the one that better describes the relationship between the stress and strain of the steel cable.
Have a nice day!
