The correct answer is B) Ultraviolet light source. Hope this helps.
Answer:
92704.5 J
596.44737 N
Explanation:
m = Mass of person + bicycle = 75 kg
g = Acceleration due to gravity = 9.81 m/s²
h = Vertical height = 126 m
= Angle = 7.7°
d = Diameter = 0.388 m
Work done against gravity is given by
Work done is 92704.5 J
Force required is given by
The force is 596.44737 N
By subtracting the value of absolute zero, also know as adding 273.15!
I don't think so it would be some where between 9 and 10
<h2>
Answer: False</h2>
Explanation:
This sentence is the description of the mechanical energy.
In this sense, the mechanical energy of a body or a system is that which is obtained from the speed of its movement (kinetic energy) or its specific position (potential energy), in order to produce a mechanical work.
That is to say: The mechanical energy involves both the kinetic energy and the potential energy (which can be elastic or gravitational, for example).
In addition, it should be noted that mechanical energy is<u> conserved in conservative fields and is a scalar magnitude.</u>
Therefore:
<h2>The sum of potential and kinetic energies in the particles of a substance is called <u>Mechanical Energy</u></h2>
