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?
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.

A tennis ball covers a distance of 12 meters in 0.4 seconds what is the velocity of the tennis ball?
Answer:
30m/s
Explanation:
Given parameters:
Distance = 12m
Time taken = 0.4s
Unknown:
Velocity of the tennis ball = ?
Solution:
Velocity of a body is the displacement per unit of time.
Velocity = [tex]\frac{displacement}{time}[/tex]
So;
Velocity = [tex]\frac{12}{0.4}[/tex] = 30m/s
Sugar dissolved in water is an example of?
A. Precipitate
B. Molecule
C. Compound
D. Solution
Answer:
D. Solution
Explanation:
Sugar dissolved in water is an example of solution.
A solution is a homogenous mixture of solutes and solvents.
In a solution the solute particles ae distributed uniformly in the solvents. The solute is the substance and it is the sugar here that is dissolved to make a solution.
The solvent is the water in this instance that helps to dissolve the solute.
Answer:
D. Solution
Explanation:
Dissolving sugar in water is an example of a physical change. Here's why:
A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result.

1)Describe the difference between an
energy transfer and energy store.
2)Give 3 examples of an energy transfer.
3)Give 3 examples of an energy store.
Answer:
1) Energy transfer is the movement of energy from one location to another. ... Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.
2)A swinging pirate ship ride at a theme park. Kinetic energy is transferred into gravitational potential energy.
A boat being accelerated by the force of the engine. ...
Bringing water to the boil in an electric kettle.
3)Common examples of energy storage are the rechargeable battery, which stores chemical energy readily convertible to electricity to operate a mobile phone, the hydroelectric dam, which stores energy in a reservoir as gravitational potential energy, and ice storage tanks, which store ice frozen by cheaper energy at night

Which of the following statements about transition metals is true?
a.
They are never found uncombined in nature.
b.
They include familiar metals such as gold, silver, copper, and nickel.
c.
They are so soft that they can be cut with an ordinary knife.
d.
They are the most reactive of all the types of metals.
Answer:
b.They include familiar metals such as gold, silver, copper, and nickel.
They include familiar metals such as gold, silver, copper, and nickel.
Transition metals are like main group metals in many ways: They look like metals, they are malleable and ductile, they conduct heat and electricity, and they form positive ions.
What are metals ?"A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable or ductile."
What are transition metals ?"Transition metals are placed between s−block and p−block elements in periodic table. They are termed as d-block elements. These metals are unstable and exhibit transitional behavior between s block and p block elements, hence the name transition metals."
What is electricity ?"Electricity is defined as the rate of flow of charges in a conductor."
Electricity is defined as the effects of an electric charge. An example of electricity is the force that powers a light bulb. An example of electricity is lightning. An example of electricity is static electricity, the buildup of electric charges on an object's surface.

1. If two objects each with the mass of 2.0 x 10^2 kg, produce gravitational force between
them of 3.7 x 10^-6N , What is the distance between them ?
Answer:
r = 0.849 m
Explanation:
Given that,
The masses of two objects, [tex]m_1=m_2=2\times 10^2\ kg[/tex]
The force between the objects, [tex]F=3.7\times 10^{-6}\ N[/tex]
We need to find the distance between the masses. The force between two objects is given by the relation as follows :
[tex]F=G\dfrac{m_1m_2}{r^2}[/tex]
r is the distance between them
[tex]r=\sqrt{\dfrac{Gm_1m_2}{F}} \\\\r=\sqrt{\dfrac{6.67\times 10^{-11}\times (2\times 10^2)^2}{3.7\times 10^{-6}}} \\\\r=0.849\ m[/tex]
So, the distance between them is 0.849 m.
Why is mineral copper often used to make electrical wires
Because copper is the second-best electrical conductor, it's cheaper and more plentiful than silver, and it's relatively easy to get it out of the ground, refine it, and form it into wires.
(If the electrical wiring in your house was all silver wire, I guess nothing would ever work, because people would keep stealing your wiring.)

A 1-kg plastic block is neutrally buoyant when submerged in water with a density of 1 g/cm3. If the same block is placed, such that it is completely submerged, in a container of oil with a density of 0.8 g/cm3, find the acceleration of the block.
Answer:
-2 m/s
Explanation:
The computation of the acceleration of the block is as follows:
The volume of the block is
V = 1kg ÷ 1,000 kg/m^3 = 1 ÷ 1,000 m^3
Now at the time of submerging in the oil
Net force is
[tex]m_g - F_B = m \times (-a)\\\\m_g - v\times S_{oil} \times g = -ma\\\\a = (\frac{v}{m} \times S_{oil} - 1) g\\\\= (\frac{1}{1000} \times 0.8 \times 1000 -1 ) \times 10\\\\[/tex]
= -2 m/s
