What is the current produced by a 9-volt battery flowing through a resistance of 0.2 ohms?
Answers
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.

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?
Answers
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.

What does the potential energy of an object depend on?
Answers
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.

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
Answers
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
A student mixes two substances in a large beaker. After two hours, the student sees that the substances have separated again.

The full question is found in the image attached
Answer:
Densities
Explanation:
When we talk about density, one of the things that come to our mind is actually how heavy something is.
If i have substances that possess different densities, i will notice that i can not really mix them because they will separate and the heavier substance will be at the bottom while the lighter substance will be at the top.
Hence the two substances separated due to difference in density.
A plane flies along a straight line path after taking off, and it ends up 90.0 km farther east and 200.0 km farther north, relative to where it started. In what direction did it fly on the straight line path?
27° north of east
45 ° north of east
24° north of east
66° north of east
Answers
Answer:
24° north of east
Explanation:
tan(x)=90/200 ie x=arctan(90/200)=24°
So the plane took off 24° east.
Answer:
24° north of east
