potential energy
A person or object may have stored energy because of its position and the energy is called potential energy.
What is potential energy?The relative positions of different system components determine the potential energy, which is stored energy. When a spring is compressed or stretched, its potential energy increases.
If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy. It is capable of performing more work when raised.
Potential energy is a characteristic of systems rather than of particular bodies or particles; for instance, the system made up of Earth and the elevated ball has more potential energy as they become further apart.
In systems having components whose forces on one another rely on their configuration, or relative positions to one another, potential energy is generated.

9) Zane has an elastic water balloon launcher that can fire balloons at an angle of [38.0o] from the surface of the ground. If the initial velocity is 25.0 m/s, find how far away are the balloons are from the launcher when they hit the level ground again.
Answer:
127.6 m
Explanation:
Given that Zane has an elastic water balloon launcher that can fire balloons at an angle of [38.0o] from the surface of the ground. If the initial velocity is 25.0 m/s,
The horizontal initial velocity will be:
U = 25cos38
U = 19.7 m/s
To find how far away are the balloons are from the launcher when they hit the level ground again, we will first calculate the total time spent before using the range formula
To calculate the total time, let's use the formula below:
T = 2U/g
T = (2 × 25)/9.8
T = 50/9.8
T = 5.1s
Range = UT
Since horizontal acceleration = 0
Range = 25 × 5.1
Range = 127.55 m
Therefore, the balloons are approximately 127.6m away from the launcher when they hit the level ground again

How does temperature influence chemical change
Answer:
yes
Explanation: if temperature is higher the reactants have more kinetic energy make the chemical reaction faster
Answer:
increasing the temperature will cause chemical changes to occur faster
Decreasing the temperature, causes the particle to lose energy which causes them to move around less and slower

How does the change in the state of matter occur? Write with example
Answer:
When matter changes from one state to another, it either absorbs energy—as when chocolate melts—or loses energy. For example, if you were to place the melted chocolate in a refrigerator, it would lose energy to the cold air inside the refrigerator. As a result, the liquid chocolate would change to a solid again.

In what ways is thermal energy transferred during physical and chemical changes
Explanation:
chemical changes
>produce new substances w/ different chemical structure/ properties
> thermal energy can be used to BREAK bonds (endothermic)
>thermal energy can be transferred to a chem rxn to help form new products (endothermic)
> heat can be released by an exothermic chemical reaction (excess energy- the total energy used to break bonds is less than energy released in forming new bonds)
physical changes
>does not result in new substances (typically changes in state- solid, liquid, gas)
> thermal energy can be transferred to EVAPORATE water (add thermal E... water (liquid) to steam (gas)) or FREEZE water (remove thermal E... water (liquid) to ice (solid))

What happens if you cut a bar magnet in half between the north and south poles?
A. one half has a north pole and one half has a south pole
B. Each half is stronger magnet than the original magnet
C. Each half has both a north pole and a south pole
D. The two halves are no longer magnetic
c is the correct answer ......... if we cut a magnet i will divide into two halves and ecah half have a southpole and northpole.
Hope it helps
When a bar magnet is cut in half, each half has both a north pole and a south pole. Therefore, option C is correct.
This phenomenon is due to the rearrangement of magnetic domains within the material. The newly formed magnets will have a north pole on one end and a south pole on the other end. This process can be repeated, resulting in smaller and smaller magnets, but each piece will always exhibit both north and south poles.
The magnetic properties are retained even when the magnet is divided into smaller segments. Each half of the magnet becomes a new magnet with its own north and south pole.

A bicycle of mass m requires 50 J of work to move from rest to a final speed v. If the same amount of work is performed during the same amount of time on a bicycle with a mass of 2m, what is the final speed of the second bicycle?
Answer:
The final speed of the second bicycle is (v·√2)/2
Explanation:
The mass of the given bicycle = m
The amount of work required to move the bicycle from rest to speed v = 50 J
The final speed of the first bicycle = v
The mass of the second bicycle = 2m
Therefore, from conservation of energy, we have;
Work required by the first bicycle = Kinetic energy gained by the bicycle
The kinetic energy = 1/2·m·v²
∴ Energy required by the first bicycle = 50 J = 1/2·m·v²
Given that the same amount of work is performed on the second bicycle, we have;
Work performed on the second bicycle = 50 J = kinetic energy of second bicycle = 1/2·(2·m)·v₂²
Also, given that 50 J = 1/2·m·v², we have;
Work performed on the second bicycle = 50 J = 1/2·m·v²= 1/2·(2·m)·v₂²
1/2·m·v²= 1/2·(2·m)·v₂²
m·v² = 2·m·v₂²
v² = 2·v₂²
v₂ = √(v²/2) = v/√2 = (v·√2)/2
v₂ = (v·√2)/2
The final speed of the second bicycle = v₂ = (v·√2)/2.
Here is the picture of an aircraft, with the forces working on it shown. Identify the force that corresponds to the question mark.
A. Buoyancy
B. Atmospheric pressure
C. Gravity
D. Density
The force corresponds to the question mark in the given figure is known as Gravity. Hence, option (C) is correct.
The given problem is based on the concept of equilibrium of forces. The forces that causes the net motion of an object to be zero, is known as equilibrium of force.
In the given problem, the lift of an aircraft will be due to the Buoyant force due to the air as a medium. The drag acting the opposite direction of motion of aircraft, tends to resist the motion. The thrust force acting on the aircraft is due to the component of aircrafts, which causes the aircraft to move forward.And the question mark shown in problem is somehow pointing the gravitational force, which always acts in downward direction. And gravitational force highlights the gravity.Thus, we can conclude that the force corresponds to the question mark in the given figure is known as Gravity. Hence, option (C) is correct.

Explanation:
A. Erosion of rock
D. Sediments are distributed by river to a new location
B. Particles settle out and form layers
E. Fossils form as living things are trapped in the layers
C. Humans analyze formations to determine the age of rock
The steps given are keys which ensures we understand how sediments form sequentially in basin of deposition. Coupled with this, we are shown a peep into the world of fossilization.
Any form of rock is first eroded before they are transported to their basins of deposition. In the basin, the particles settle out and form layers. The fossils trapped in them also settles out. The sediments gets compacted to sedimentary rocks. This sequence is therefore analyzed to determine the age of a rock.What is the difference between scalar and vector quantity?
Answer: A scalar quantity has magnitude but no particular direction and a vector quantity has magnitude and acts in a particular direction.
