Explanation:
The given data is as follows.
Distance (s) = 20 m
time (t) = 0.775 s
Also, it is given that mass per 1 meter length (m) = 0.300 kg
Formula to calculate the velocity is as follows.
Velocity (v) = 
Putting the given values into the above formula as follows.
v =
= 
= 25.80 m/s
We know that,
v = 
Taking square on both the sides, the formula will become as follows.
T = 
= 
= 199.692 N
Therefore, we can conclude that tension in the given tightrope is equal to 199.692 N
.
Answer:
33,333.3J/s
Explanation:
Energy expended which is the work done in Joule
=250,000J
Time taken to expend the energy =7.5s
Power =Unknown
Formula
Power = <u> </u><u> </u><u> </u><u> </u><u> </u><u>Work</u><u> </u><u> </u><u> </u>
Time
Hence, Power = <u>250,000J</u>
7.5s
Power = 33,333.3J/s
Answer:
the correct answer is B
Explanation:
The kinetic model of the movement describes that the movement of the molecules increases with the increase of their internal energy, which in a macroscopic sample is reflected in an increase in the temperature of the sample.
The sample graph shows the function of temperature over time, which is why our kinetic model establishes that there is an increase in the movement of water molecules.
Consequently the correct answer is B
Answer:
When LeBron James jumps, he is driving force into the court. How is this force created? Suggested answer: This force is created by the energy stored inside his muscles.
Explanation:
The force is reasonable for making fusion possible in the Sun is heat energy.
<h3>What is nuclear fission and fusion?</h3>
When the slow moving neutrons are bombarded with the heavy radioactive nuclei, the product is the more number of neutrons are produced with the large amount of energy. This multiplying process is called nuclear fusion.
The amount of energy produced in such a reaction can be calculated using the equivalence of mass and energy relationship.
E = mc²
The same happens in nuclear fusion where large amount of energy is needed to make more heavy nuclei.
Thus, fusion requires heat energy to continue the reaction.
