Potential energy = (mass) x (gravity) x (height)
Divide each side by (G x H) : Mass = PE / (G x H)
PE = 6 joules
Gravity = 9.8 m/s
Height = 3 m
Mass = 6 / (9.8 x 3) =
6 / (29.4) = <em>0.204 kg</em>
(weighs about 2 newtons or 7.2 ounces on Earth)
Answer:
0.85V
Explanation:
The emf is calculated by using the Lenz's Law
But for this case we have that the magnetic field is constant. Hence we have
where we have taken that the intial time is t1=0
I hope this is useful for you

One advantage of using primary sources when doing research on an experiment is, it contain more details about the experiment. Thus, option D is right .
To find the answer, we have to know more about the Primary sources.
<h3>
What is the advantages of primary sources?</h3>
- Primary sources are the direct or first-hand excerpts that scientists have independently written based on their experiments in order to support their research.
- Utilizing original sources encourages analytical and critical thought in relation to the research.
- It aids in exploring from various angles, which leads to the discovery of extra facts.
- Primary data aids in navigating the conflicts. Since it is a direct resource related to the experiment, it serves as evidence for the data.
Thus, we can conclude that, Primary sources contain more details about the experiment.

Answer:
medium
Examples:
A medium is a thing that the sound wave would travel through, like sound waves traveling through air. A mechanical wave cannot travel without a medium, like if the wave were trying to travel through a vacuum.
A. anything less than 3.0 magnitude on a richters scale usually can't be felt by humans but instruments can pick it up.
