There are different kinds of conductors, most notably electrical and thermal conductors. But they are often inclusive of each other (electrical conductors are typically good thermal conductors).
A conductor transmits something through its body with high efficiency while an insulator does not transmit very well. In the case of electricity, a conductor transmits electrical energy between two points while an insulator blocks the flow of electricity.
Two examples of conductors are copper and silver. Two examples of insulators are wood and styrofoam.
Answer:
The cross-sectional area of the larger piston is 392 cm²
Explanation:
Given;
output mass of the piston, m₀ = 2000 kg
input force of the piston, F₁ = 500 N
input area of the piston, A₁ = 10 cm² = 0.001 m²
The output force is given by;
F₀ = m₀g
F₀ = 2000 x 9.8
F₀ = 19600 N
The cross-sectional area of the larger piston or output area of the piston will be calculated by applying the following equations;
Therefore, the cross-sectional area of the larger piston is 392 cm²
Answer:
The magnetic force on the wire at the moment is 2 micro-Newton/(Ampere-meter)
Explanation:
Formula for magnetic force is F = qvB*sin(theeta)
and B = μ*I / 2*pi*r
where
q = charge in coulomb
v = velocity
B = magnetic field strength
μ = permeability of free space
I = current
so from here we get B = (4*pi*10^(-7))(5) / 2*pi*0.01 = 0.0001-T
now ,
F = (2mC)*(10)*0.0001*sin(90)
F = 2 micro-Newton/(Ampere-meter)
The object is moving at a constant speed
