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
The formation of new elements through the process of fusion in a star’s core stops at iron. How are elements larger than iron formed?
Answer:
During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced. In the supernova explosion, all of these elements are expelled out into space.

Explanation:
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.

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.
