Answer:

A force is a vector quantity which means that it has both a magnitude (size) and a direction associated with it.

Explanation:

If an object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations.

Answer:

Yes.

Explanation:

Because mass and velocity are directly proportional to kinetic energy.

Explanation:

Conduction is the transfer of energy from one molecule to another by direct contact.

The air will move from area Y to area X.

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.

Explanation:

Answer:

C and F are the same because they are buried in the same spot and have the same fossilized creature.

I'm very sorry but for the second question I'm confused:(

Answer: I could be wrong but according to Newton’s third law of motion, for every action, there is an equal and opposite action, so for every answer, just find an arrow that’s the same size as the blue one and make the arrow point in the opposite direction that the blue one is pointing to

Person getting warm from an electric blanket is an example of heat transfer by 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

Answer:

Absorb oxygen and nutrients.
Surround Alveoli.

Explanation:

Absorbing Nutrients takes place in the intestines where the walls are richly supplied with blood vessels to maximise absorption of nutrients.
Absorbing Oxygen takes place in the lungs , specifically the alveoli. The Alveoli is covered with cappilaries whose function is to exchange gases.

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.

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.

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.

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.
