The statement 'Not all metals have the same current for a given electric potential' is TRUE. It is conductivity.
<h3>What is conductivity?</h3>
All the metals are able to conduct electric currents, but some metals have a higher conductivity.
Metals are able to conduct electric currents due to the free movement of negatively charged particles i.e., electrons, across the conductor.
The band theory of metals states that metals can conduct electrons (e-) in an electric current by means of the help of the e- valence.
The density of free electrons in metals is around 10^28 m-3, which indicates the number of states at a particular energy level that negative e- can occupy.

Answer:
F = 153637 lb
Explanation:
Let's use the kinematic equations to find the airplane's braking speed
v² = v₀² + 2 a d
The final speed is zero
a = - v₀² / 2d
Let's reduce the magnitudes
v₀ = 110 mi / h (5280 ft / 1 mile) (1 h / 360 s) = 161.33 ft / s
a = -161.33²/2 90
a = -144.60 ft / s²
Now we can use Newton's second law to find the tension
F = m a
F = (34000/32) 144.60
F = 153637 lb
Answer:
The point through which the Whole mass of the body acts, irrespective of the position of the body, is known as centre of gravity (briefly written as c.g.). ... Mass affects the centre of gravity of the object.
Explanation:
KE= (1/2) mv²
So, the variables we need to include in our question would be a varable for a mass(m) of an object at some velocity(v).
My Answer:
(This is just an example question, yours can be different)
What is the Kinetic Energy experienced by an bouncy ball rolling at 7m/s (that's your velocity) across a frictionless surface that has a mass(m) of 10 grams?
Hi there!
Using the equation for the electric field produced by an infinite sheet of charge:
E = Electric field strength (150 N/C)
σ = Surface charge density (? C/m²)
ε₀ = Permittivity of free space (8.8542× 10⁻¹² C²/Nm²)
We can rearrange the equation to solve for the surface charge density (charge per unit area)
