What is the current produced by a 9-volt battery flowing through a resistance of 0.2 ohms?
Answer:
45 AmpereExplanation:
R=V/I I=V/R V = 9 R=0.2 I = 9/0.2 = 9×10/0.2×10 =90/2 ie, I =45 AThe current produced by a 9-volt battery flowing through a resistance of 0.2 ohms would be 45 Ampere.
What is resistance?
Resistance is the obstruction of electrons in an electrically conducting material.
The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.
V=IR
As given in the problem we have to find the current produced by a 9-volt battery flowing through a resistance of 0.2 ohms.
current produced by a 9-volt battery = voltage /resistance
= 9 volt /0.2 ohms
= 45 Ampere
Thus, the current produced would be 45 Ampere.

What does the potential energy of an object depend on?
Answer:
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds.
Hope this helps :)
A spring has a force constant of 40000 N/m.
How far must it be stretched for its potential energy to be 42 J?
Answer in units of m
Answer:
0.05m
Explanation:
Given parameters:
Force constant of the spring = 40000N/m
Potential energy = 42J
Unknown:
Extension = ?
Solution:
To solve this problem, use the expression below:
E.PE = [tex]\frac{1}{2}[/tex] k e²
k is spring constant
e is the extension
42 = [tex]\frac{1}{2}[/tex] x 40000 x e²
e = 0.05m
