Michelle melted a compound in the lab and performed the same procedure five times. The chart below shows the time it took for the compound to melt during the five trials.Trial Time (min:sec) 1 3:14 2 3:10 3 4:05 4 3:12 5 3:09 After reviewing her data, she realized that trial 3 was vastly different from the other four trial times. Which of the following reasons could explain the radical difference in melting time for trial 3? A larger quantity of compound was used in trial 3. The compound started at a lower temperature in trial 3. The burner was not directly under the compound during trial 3. all of these

The conversion of carbon dioxide to oxygen by plants is called _____. A. polysynthesis B. photosynthesis C. amino-acid synthesis D. amino-acid production

Answers

The conversion of carbon dioxide to oxygen by plants is called photosynthesis.
The answer would be B, photosynthesis. 
Using the process of elimination, the answer is easy to find.

Polysynthesis - The act or process of combining many separate elements into a whole (Free Dictionary)

Amino-acid Synthesis - No definition, but this is clearly not the answer as amino acid has nothing to do with carbon dioxide or oxygen.

Amino-acid Production - This doesn't work for the same reason as the last one. Amino acid is irrelevant.

Therefore, the answer is photosynthesis.

In a nuclear reactor, the moderator is: usually made of graphite placed between the fuel rods used to slow down neutrons all of the above none of the above

Answers

The correct answer is all of the above. In a nuclear reactor, the moderator is usually made of graphite, placed between the fuel rods, and used to slow down neutrons. The nuclear moderator is a medium in which reduces the speed of the fast neutrons.  

The answer is D. All the above

Answers

Joule is the unit of work .

What is meant by work ?

Activity that a person habitually engages in to earn a living is activity that persons looking for job engage in.

Activity in which one utilises strength or faculties to do or do anything. a particular duty, responsibility, function, or assignment that often forms a component or stage of a bigger action.

Thus, Joule is the SI unit of work (J). The work accomplished by a force of one newton creating a displacement of one metre is known as a joule.

A constant net torque is applied to a rotating object. Which of the following best describes the object's motion?a. The object will rotate with increasing angular acceleration.
b. The object will have a decreasing moment of inertia.
c. The object will rotate with constant angular velocity.
d. The object will have an increasing moment of inertia.
e. The object will rotate with decreasing angular acceleration.
f. The object will rotate with constant angular acceleration.

Answers

Answer:

f. The object will rotate with constant angular acceleration.

Explanation:

We know that

τ = I α

τ=Torque

I=Moment of inertia of the object

α =Angular acceleration

The moment of inertia is constant for an object and it does not depends on the applied torque.

If applied torque is constant then the angular acceleration of the object will be constant because moment of inertia is constant.

If angular speed is constant then the angular acceleration will,be zero.But in this case object is having angular acceleration that is why it have varying angular speed.

Therefore option "f" is correct.
