How is static electricity created?

a. Two objects that are both positively charged repel each other and release
electric energy.


b. Two objects that are both negatively charged become attracted and create a
spark.

c.
Two highly conductive materials are placed within close proximity of one
another.
d. Friction between two objects causes a transfer of electrons from one object to
the other.
.

Answers

Answer 1

Answer:

d

Explanation:

So, when a person or any object has extra electrons, it creates a negative charge. These electrons thus get attracted to positive electrons (as opposite attracts) of another object or person and vice versa. The shock that we feel sometimes is the result of the quick movement of these electrons.

The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons.

Answer 2

Answer:

d. Friction between two objects causes a transfer of electrons from one object to  the other.

Explanation:

If electrons are transferred by rubbing two objects together, the result of the friction is that one object becomes positively charged by losing electrons, and the other object becomes negatively charged by gaining them. This is known as static electricity.

How does being small help cells survive?

Answers

Cells are small in size because it is very important that they have a surface area to volume ratio that would allow adequate intake of food nutrients, as well as the excretion of waste materials.

A cell can be defined as the fundamental (basic), functional, structural and smallest unit of life found in all living organisms.

According to cell type, living organism are mainly divided into two (2) main groups and these are;

Unicellular organisms: these are living organisms that are single-celled i.e they have a single cell.Multicellular organisms: this category of living organisms have many (multiple) cells.

It is very important that the surface area to the volume ratio of cell is small, so as to allow enough materials such as food, move through the cell membrane quickly for the survival of the cell.

Hence, cells are small in size because it is very important that they have a surface area to volume ratio that would allow adequate intake of food nutrients, as well as the excretion of waste materials.

In conclusion, the smaller a cell, the larger would be its surface area to volume ratio.

Snow slides down a mountain in an avalanche. Where would the snow have the
most potential energy?

Answers

Answer:

At the top of the mountain

Explanation:

The snow will have the most potential energy at the top of the mountain. Potential energy is the energy at rest of a body. It is a function of the mass, acceleration due to gravity and height of the body.

                              P.E = mgh

Since at the top of the mountain, we have the highest elevation. So, we expect that at the peak of the mountain the potential energy will be highest here.

B) Digestive enzymes breaking down proteins into smaller fragments

C) bacteria converting lactose into simple sugars in the intestines

D) teeth grinding an almond into smaller pieces in the mouth

The answer is D

Explanation:

A physical change is a change that occurs to a substance without altering its chemical composition. A physical change involved a change in the substance's shape, texture, color, state etc. but not the chemical content of such substances.

In this question involving the processes that occur in digestion, a typical example of physical change is "teeth grinding an almond into smaller pieces in the mouth" because the teeth only changes the shape and texture of the almond. It does not affect the chemical composition of the almond fruit. This is also called mechanical digestion.

Note that, other options involving digestive enzymes breakdown are chemical changes because the enzymes breakdown the chemical components of each substance.

Answer: D

Explanation: because you are breaking down food in a physical change
