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!
Answer:
Resistance = 252.53 Ohms
Explanation:
Given the following data;
Charge = 0.125 C
Voltage = 5 V
Time = 6.3 seconds
To find the resistance;
First of all, we would determine the current flowing through the battery;
Quantity of charge, Q = current * time
0.125 = current * 6.3
Current = 0.125/6.3
Current = 0.0198 A
Next, we find the resistance;
Resistance = voltage/current
Resistance = 5/0.0198
Resistance = 252.53 Ohms
Answer: You could figure out the velocity using the acceleration and time.
Answer:
20 N
Explanation:
The gravitational force for block B will be given by mg where m is mass of the block and g is gravitational constant, in this case taken as
Substituting 2 Kg for m we obtain
Fg=2*10=20 N
Therefore, the gravitational force exerted by block B is nearly 20 N and acts downwards
Because the average of one measurement would yield to itself, which provides nothing new to us. We need at least two for average to be purposeful.
