Not all metals have the same current for a given electric potential
Neporo4naja [7]

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.

If a net horizontal force of 7.5 N is applied to a baby carriage whose mass is 12.5 kg what acceleration is
11111nata11111 [884]

Answer:

<h2>0.6 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m} \\

f is the force

m is the mass

From the question we have

a =  \frac{7.5}{12.5}  \\

We have the final answer as

<h3>0.6 m/s²</h3>

Hope this helps you
