what is one way that water can impact the weather and how that can affect humans.
Answers
The water cycle contributes to the movement of hot and cold air.
The water cycle is how clouds originate, as most of the water that makes up rain and snow evaporates from the ocean.
Precipitation in the sky has an impact on the weather on several levels.
The wind is influenced by the water cycle.
While the ocean and land are the primary generators of wind, water in the atmosphere retains heat and can be used to create and redirect it.
I hope this helps! :)
Which option is an example of heat transfer by conduction?
A. person getting warm from an electric blanket
B. pavement heating up in the sun
C. air conditioner cooling the room
D. air getting warm from a radiator
Answers
Person getting warm from an electric blanket is an example of heat transfer by conduction.
What is conduction?
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction

What is pressure gradient?In atmospheric science, the pressure gradient ( generally of air but more generally of any fluid) is a physical volume that describes in which direction and at what rate the pressure increases the most fleetly around a particular position. SI Unit of pressure gradient is Pascal per meter( Pa/ m). Mathematically, it's the gradient of pressure as a function of position.
As temperature of air rises, the volume of air increases, that is, density of air decreases. As a result, pressure at high temperature area also decreases. Air generally moves from an area at high pressure to a area of low pressure. So following pressure gradient , air moves from low temperature area to high temperature area.
According to given data, temperate of area X is greater than both area Y and Area Z.
Hence, air will move from area Y to area X.

Answer: A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs when a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment. The size and shape of a delta is controlled by the balance between watershed processes that supply sediment.

How are air temperature and air pressure related?
Low air temperature causes the air particles to be packed together, creating high air pressure.
Low air temperature causes the air particles to spread out, creating low air pressure.
High air temperature causes the air particles to rise, creating low air pressure.
High air temperature causes the air particles to stay close to the ground, creating high air pressure.

An iron needle has been given a positive charge.
Which type(s) of fields will exert a force on the needle?
A) only a magnetic field
B) only a magnetic and an electrical field
C) only an electrical and a gravitational field
D) a magnetic, an electrical and a gravitational field
Answers
An iron needle has been given a positive charge. A magnetic, an electrical and a gravitational field will exert a force on the needle. Hence, option (D) is correct.
What is electric field?The electric field is mathematically defined as a vector field associated with each point in space, the force per unit charge exerted on a positive test charge at rest at that point.
The electric charge or time-varying magnetic fields generate the electric field. At the atomic level, the electric field is responsible for the attractive forces that hold the atomic nucleus and electrons together.
On iron needle initially, electrical and a gravitational field exert a force. When it has been given a positive charge, magnetic field adds. So, a magnetic, an electrical and a gravitational field will exert a force on the needle.

Second question: A ball with a mass of 5.0g is moving at a speed of 2.0 m/s. Would doubling the mass or doubling the speed have a greater effect on the kinetic energy of the ball? Explain.
Answers
Answer:
When you lift a book from the ground to your desk, you do positive work. By lifting the book, you are increasing the object's gravitational potential energy. The book gains energy. It is gravitational potential energy.
Explanation:
Positive work is said when the force exerted on the object is in the same direction as that of the direction of its displacement.
Negative work is said to be done when the force exerted on the object is in the opposite direction as that of the direction of its displacement.
In this case, the force exerted on the book is in the upward direction and is in the same direction as that of its displacement. Hence, we are doing a positive work. Gravity is doing a negative work.
When we lift the book, we are changing its location from ground to the desk and in this process, the book is gaining energy. The energy gained by the object is gravitational potential energy.
Gravitational potential energy is the energy which is possessed by the virtue of the object's position of location.
Answer:
1)When I lift the book, I do positive work. By lifting the book I change its location. The book is gain energy and it is potential energy.
2)Doubling the mass or doubling the speed will have a greater effect on the kinetic energy of the ball. Because doubling the mass would have a greater effect on the kinetic energy of the ball because you are dividing the mass by velocity and if you have a greater mass that means a bigger answer.
