Answer:
A. TA = TB/2.
Explanation:
Since container A has half as many molecules of the ideal gas in it as container B. Therefore, container A will have half the volume of gas as in container B:
Now, from Charle's Law:
Hence, the correct option is:
<u>A. TA = TB/2.</u>
Answer:
B. A wave of visible light is produced.
Explanation:
The visible light spectrum is in the centre of the Electromagnetic Spectrum, so any time an electron jumps from high to low levels of radiation, it has to cross through the visible spectrum.
I hope this is correct, and as always, I am joyous to assist anyone at any time.
Answer:
The correct option is;
c. He conducted experiments with balls and inclined planes
Explanation:
The inclined plane experiment conducted by Galileo Galilei was one of his most important experiments.
The experiment consisted of a grooved board with which a small metal ball is rolled down in, so as to analyze the held Aristotelian ideas about motion.
In the experiment, the focus was on acceleration, a concept that the previously held ideas about motion
To calculate the average acceleration of the ball we use the formula,
Here, 
is the final velocity of the ball and 
is the initial velocity of the ball t is the time in contact with the wall.
Given 
towards the wall and 
away from the wall and 
.
Substituting these values in above formula , we get
Here is negative because ball is moving away from the wall.
Therefore, average acceleration of the ball is 
(away from the wall).
