As an object falls to the ground, its potential energy is being converted to kinetic energy.True
False

Answers

Answer:

The statement is true

Explanation:

Energy Conversion

When an object starts to fall in free air, it speeds up as it falls. The force of gravity acting on the object causes energy to be transferred from its gravitational potential energy to its kinetic energy. We can safely say the height converts to speed and vice-versa. If no external forces act on the system, we can easily calculate heights and speeds by knowing the total mechanical energy (gravitational potential plus kinetic) is conserved.

All charged objects create an electric field around them. What two factors determine the strength of two electric fields upon the charged objects creating them?

Answers

-- The product of the magnitudes of the two charges.
-- The distance between the centers of the two charges.

The signs of the charges ... whether their signs are the same
or opposite ... determines the direction of the forces, but not
their magnitude.

Label the parts of the brain. medulla oblongata thalamus cerebrum cerebellum brain stem pons hypothalamus midbrain

Answers

Answer:

Medulla oblongata is lower part of brain.

Cerebrum and cerebellum are the upper hemispheres of the brain.

Explanation:

Cerebrum is the largest part of the brain and is composed of right and left hemispheres.

Cerebellum is the part of brain that lies inside the cerebellum.

Medulla Oblongata is lowest part of brain stem which is most vital part of the brain.

Thalamus is a small region of the brain located above the brain stem. Its main function is to transmit sensory signals to cerebral cortex.

Brain stem act as relay center connecting the cerebrum and cerebellum to the spinal chord.

Hypothalamus is the mid brain located near the pituitary glands. It is very small region of the brain but it plays an important role in maintaining the body temperature and releasing the hormones.

Answer:

Medulla oblongata: The bottom part of the brainstem helps regulate your breathing, heart rhythms, blood pressure and swallowing.

What is the smallest unit that makes up matter

Answers

The smallest unit that makes up matter is atom. The correct option is A.

The atom is the smallest component of matter. The fundamental units of matter, or atoms, cannot be further divided without losing their essentialcharacteristics.

They have an orbitally arranged nucleus of protons and neutrons that surrounds them. Molecules, which are collections of atoms bound together, are created when various atom kinds are combined.

On the other hand, cells, which are made up of different molecules, are the fundamental structural and functional units of living things.

Protons are subatomicparticles that can be found in the atom's nucleus, however they are not the tiniest piece of matter.

Thus, the correct option is A.

What is air resistance a form of? Define air resistance

Answers

Answer:

By definition, air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the oncoming flow velocity, thus slowing the object down.
