Answer:
D
Explanation:
The gravity is pushing the water downward so Wayne could go down but the water is pushing Wayne to go up which would make him float.
Answer:
The statement is true
Explanation:
The Gibbs free energy is defined as:
ΔG = ΔH - TΔS
Where ΔH : Change in the enthalpy
T : The temperature
ΔS : Change in the entropy
And the Gibbs free energy is a thermodynamic potential that can be used to calculate the maximum of reversible work that may be performed by a thermodynamic system at a constant temperature and pressure.
If the thermodynamic process is isothermal and isobaric, then the statement is true.
0.4375 m/s^2
Acceleration is change in velocity over time
Change in velocity (Vf-Vi) 9.7m/s - 6.2m/s = 3.5 m/s
Time is 8 seconds
Acceleration = 3.5m/s / 8s = 0.4375 m/s^2
The average current density is 7.6 × 10⁵ A/m².
To calculate the current density current will be 2.4 A.
Diameter of a wire = 2mm.
The cross-sectional area of the wire is given by r = d/2
where r is the radius of the wire.
Then, the cross-sectional area is = 0.00000314159265
= 3.1 × 10⁻⁶ m².
<h3>
What is average current density?</h3>
Consider a current carrying conductor, the current density depends upon the current flow in the conductor. If the current flow in the conductor will be high then the current density will also be high. Using the average current flowing through the conductor, the average current density will be found.
Average current density j = I / A Ampere/ meter².
By substituting the values in the formula,
j = 2.4 / ( 3.1 × 10⁻⁶)
= 7.6 × 10⁵ A/m².
Hence, the current density can be calculated.
