Answer:
2 ohms
Explanation:
Hi there!
Ohm's law states that where V is the voltage, I is the current and R is the resistance.
Plug in the given information (I=7.5, V=15) and solve for R
Divide both sides by 7.5 to isolate R
Therefore, the circuit resistance would be 2 ohms.
I hope this helps!
Answer:
a=2.304×10¹⁶m/s²
Explanation:
Given data
Distance d=2.5 nm=2,5×10⁻⁹m
Mass of proton m=1.6×10⁻²⁷kg
charge of proton q=1.6×10⁻¹⁹C
To find
acceleration a
Solution
Apply the Coulombs Law
Where k is coulombs constant (k=9×10⁹Nm²/C²)
q=q₁=q₂
r=d
So
Answer:
The current in the wire is 31.96 A.
Explanation:
The current in the wire can be calculated as follows:
<u>Where</u>:
q: is the electric charge transferred through the surface
t: is the time
The charge, q, is:
<u>Where</u>:
n: is the number of electrons = 7.93x10²⁰
e: is the electron's charge = 1.6x10⁻¹⁹ C
Hence, the current in the wire is:
Therefore, the current in the wire is 31.96 A.
I hope it helps you!
