Which household item uses radiation in a beneficial way? conventional ovens smoke detectors electric air filters computers and TV sets
Answer:
Smoke detectors
Explanation:
This is because the ionization chamber in smoke detectors uses radiation, a form of heat transfer to detect smoke.
.The NRC allows beneficial use of smoke detectors which is a radioactive material because a smoke detector has the ability to save lives . it's ability to save lives outweighs any health risk from the radiation. The smoke detector use a very minimal amounts of radioactive materials.
Answer: The household item which uses radiation in a beneficial way is the SMOKE DETECTORS
Explanation:
Radiation is a type of energy that has the ability to travel through space and penetrate materials. There are various types of radiation which include alpha, beta and gamma rays. Many uses of radiation help to ensure high quality and safety of our daily lives. A typical example is seen in smoke detectors.
Smoke detectors are devices installed in a building which serves the purpose of detecting smoke which usually is associated with fire and sounding off an alarm. The types of smoke detectors available depends on their mode of action and these include:
--> Ionization smoke detectors: These type of detector are generally more sensitive to flamming fires. They have an in built small amount of RADIOACTIVE material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm. An isotope of americium which emits alpha particles is used in this type of smoke detectors and it's an example of an alpha radiation.
Therefore, the household item which uses radiation in a beneficial way is the SMOKE DETECTORS.

When we touch a Van de Graaff generator, our hair may stand up if it is dry. This happens only if the strands of our hair do what?
Answer:
Repel each other.
Explanation:
Van de Graaff generator is a device that was invented in 1929, by an American physicist called Robert J. Van de Graaff.
A Van de Graaff generator refers to an electrostatic generator that typically involves the use of a moving belt to accumulate electric charge on a hollow globe that is made from metal placed on top of an insulated column and thereby, creating very high electric potentials i.e very high voltage-direct current (DC) electricity at low current levels.
Generally, when we touch a Van de Graaff generator, our hair may stand up if it is dry. This happens only if the strands of our hair repel each other because they are like charges i.e having the same potentials.
What is the law of inertia? Give an example of inertia in action.
Answer:
The law of inertia is another name for Newton's first law. Newton's first law states that an object will not change its motion or direction unless a force acts on it. An object at rest will stay at rest and an object in motion will stay in motion if there isn't any force acting on them.
Example: When a car uses its brakes to stop, you sometimes feel like you are sliding forward. That is because the inertia keeps you moving forward, even though the car stopped.
Explanation:
Answer:
Law of inertia is sometimes called Newtons First law of motion.
Newtons first law of motion states that"A body will continue to its state of rest or motion unless external force acted upon it.

10 minutes on the stove, the water molecules in the pot are in two different
states Identify the two different states of water molecules in the pot. Then, compare the
motion and the energy of these two types of water molecules,
Answer:
20 molcues
Explanation:
10 minutes on the stove, the water molecules in the pot are in two different states , the two different states are the liquid state and the gaseous state.
What is the matter ?Anything which has mass and occupies space is known as matter, mainly there are four states of matter solid liquid gas, and plasma .
These different states of matter have different characteristics according to which they vary their volume and shape .
As given in the problem 10 minutes on the stove , the water molecules in the pot are in two different states , the two different states are liquid state and the gaseous state ,
The gaseous state of the water molecules has higher energy and then motion as compared to the liquid state of the water molecule .

A student is creating a model of a concave lens. The diagram shows her incomplete model.
Which action would best complete her model?
A
The student should draw the light moving into the lens and then exiting in converging lines.
B
The student should draw the rays of light moving into the lens and then exiting at right angles.
C
The student should draw the rays of light moving into the lens and then exiting in a straight path.

A student has two identical sheets of paper. He crumples one up into a small ball. If he drops the sheet of paper and the ball of paper off a building at the same time, which of the following statements describes the result?
A. The sheet of paper because it is more affected by gravity.
B. The ball of paper hits the ground first because it is more affected by gravity
C. The sheet of paper and the ball of paper hit the ground at the same time.
D. The ball of paper hits the ground first because it has less surface area.
Answer:
B
Explanation:
basically, because the ball "weighs" more now, it will hit the ground quicker. so technically gravity is more affective towards it. the piece of paper kind of floats it's way down. gravity isn't pushing on one force more, but because because the ball weighs more, it technically would be said so. hope this helps!
Answer:
the ball of paper, because it has less surface area.
Explanation:

(True/False) According to Newton’s third law of motion, it is true that an object moving at a constant speed in a straight path will continue to do so until a net force acts upon it.
The statement itself is true. But to be completely and compulsively correct, that's Newton's FIRST law of motion, not the third.
