Atoms have no electric charge because theyA. Have an equal number of charged and non charged particles.

B. Have neutrons in their nuclei.

C. Have an equal number of electrons and protons

D. Have an equal number of neutrons and protons

Answers

Answer 1

Answer:

Atoms have no electric charge because they have an equal number of electrons and protons.

Explanation:

Atom is the smallest unit of matter.

It is comprised of three subatomic particles:protons, electrons, and neutrons.
Electrons are found outside the nucleus of an atom and are negatively charged.
Protons are found inside the nucleus of an atom and are positively charged.

Neutrons are found inside the nucleus of an atom and have no charge.
They are electrically neutral because they have an equal number of protons and electrons.

So from this, we can conclude that atoms have no electric charge because they have an equal number of electrons and protons. Option C is correct.

Which statement is true about how objects appear to bend that are partially submerged in water?They appear to bend at the surface due to reflection.
They appear to bend at the surface due to refraction.
They appear to bend at the surface due to diffraction.
They appear to bend at the surface due to interference

Answers

The correct answer to the question is: B) They appear to bend at the surface due to refraction.

EXPLANATION:

When light moves from optical rarer medium to optical denser medium, the light rays are bent towards the normal at the point of incidence on the refracting surface. If the order is changed, then the way will be away from the normal.

This property of light is known as refraction which is due to the fact that light has different velocities in different media.

As per the question, the object appears to be bent when it is submerged in water. Actually the object is not bent. Its the light from object which is bent at the air-water interference.

Hence, the correct answer of this question is refraction.

After France fell to the Axis powers in 1940, what percentage of the country was placed under German control?A. 25 percent
B. 50 percent
C. 60 percent
D. 100 percent

Answers

Correct answer choice is:

B. 50 percent

Explanation:

France Capitulates to Nazi Germany. On June 22, 1940, the French state approved a cease-fire with Nazi Germany just six weeks after the Nazis began their incursion of Western Europe.

Paris began preparing for combat in September 1939, when Nazi Germany overran Poland, but the combat appeared far beyond until May 10, 1940, when the Germans invaded France and immediately took the French troops. The French administration left Paris on June 10, and the Germans controlled the capital on June 14.

25 % of the population was in controlled by Germany after France fell to the Axis power. Germany ruled over France and made things that caused the French people to create a revolution. This was one of the greatest revolution so far in the history where the French people united just to get their freedom back.

State the law of universal gravitation, and use examples to explain how changes in mass and changes in distance affect gravitational force.

Answers

F(g)= Gm1m2/ r^2 If mass is increased, so will the force of gravity because it is in direct relationship with the gravitational force, but if distance is increased, the force of gravity will decrease because it is indirectly related ( since it is on the bottom of the equation)

Which of these objects would show the greatest parallax?a. the Sun
b. Mars
c. the Moon
d. Polaris
What is the distance an object would be from Earth if its parallax were one arcsecond?
a. a parsec
b. a light-year
c. an arcminute
d. an angular diameter

Answers

The sun's parallax would be 180 degrees, greater than which you can't get.

If an object exhibits a parallax of 1 arc second, then its distance from us
is called one 'parsec'. That distance is about 3.26 light-years.

Which of the following is the best example of a compression force?a. dragging a rope to move a sled
b. the force of weight on a bicycle
c. typing the computer key for the letter y
d. the force of a picture hanging on a nail

Answers

The best example of a compression force is the force of weight on a bicycle. The answer is letter B. A compression force is when the weight of the bicycle imposes a downward force to the ground and the ground imposes an upward force to the bicycle.

I took the test and got B) the force of weight on a bicycle correct
