Potential Energy (P.E) = Mass x
Acceleration due to Gravity x Altitude. Putting this value in the above equation we get, Dimensional Formula of
Potential energy= M1L2T-2.
Given Information:
Current = I = 20 A
Diameter = d = 0.205 cm = 0.00205 m
Length of wire = L = 1 m
Required Information:
Energy produced = P = ?
Answer:
P = 2.03 J/s
Explanation:
We know that power required in a wire is
P = I²R
and R = ρL/A
Where ρ is the resistivity of the copper wire 1.68x10⁻⁸ Ω.m
L is the length of the wire and A is the area of the cross-section and is given by
A = πr²
A = π(d/2)²
A = π(0.00205/2)²
A = 3.3x10⁻⁶ m²
R = ρL/A
R = 1.68x10⁻⁸*(1)/3.3x10⁻⁶
R = 5.09x10⁻³ Ω
P = I²R
P = (20)²*5.09x10⁻³
P = 2.03 Watts or P = 2.03 J/s
Therefore, 2.03 J/s of energy is produced in 1.00 m of 12-gauge copper wire carrying a current of 20 A
Answer:
energy is stored is 2.2 × 10⁻¹³ J
Explanation:
The capacitance of the cell is given with the expression
C = (KE₀A) / d
k is the dielectric constant, A is the area of the cell, d is the thickness of the cell.
Now given that; the diameter is 50,
Area A = 4πR²
A = 4π × ( 25 × 10⁻⁶ m)²
A = 7850×10⁻¹² m²
our capacitance C = (KE₀A) / d
C = [9 ( 8.85 × 10⁻¹² C²/N.m² × 7850×10⁻¹² m² )] / 7×10⁻⁹ m
C = 8.93 × 10⁻¹¹ F
Now Energy stored
E = 1/2 × CV²
E = 1/2 × (8.93 × 10⁻¹¹ F) × ( 70 × 10⁻³ V)²
E = 2.2 × 10⁻¹³ J
Therefore energy is stored is 2.2 × 10⁻¹³ J
Answer:
The value is 
The force will be outward
Explanation:
From the question we are told that
The diameter of the disk is 
The external pressure on Mars is 
From the question we are told that
Internal pressure = External pressure
Generally the external Force on earth is
Here 
is the atmospheric pressure with value 
So
=> 
=> 
Generally the external Force on Mars is
=> 
=> 
Net force is mathematically represented as
=> 
=> 
converting to pounds
=>
Given that that the value is positive then the force will be outward
Energy: the capacity for vigorous activity; available power.
Kinetic Energy: the energy of a body or a system with respect to the motion of the body or of the particles in the system.
Law of Conservation of Energy: energy cannot be created or destroyed, but it can be transferred or transformed from one form to another.
Potential Energy: the energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system.
Transfer: to move energy from one to another.
Transform: to change in form, appearance, or structure; metamorphose.
next time you need definitions quickly looking up a dictionary would be faster, anyways hopefully this can be helpful.
