Hi there!
Recall the equation for work given a potential difference and charge:
W = Work (J)
q = charge (C)
V = Potential difference (V)
The work is equivalent to the change in KINETIC ENERGY, and only depends on the particle's charge and the potential difference that it experiences. Mass has no impact on this.
Thus:
This is equivalent to:
Answer:
The correct answer is - 63.61 miles/hour.
Explanation:
Meter and miles both are the measuring units of distance and speed units are meter per second and miles per hour. The numerical relation between these two units are as follows:
1 meter per second = 2.24 miles per hour
The car travels 28.4 m/s so in miles per hour it would be:
So, 28.4 meters per second = 28.4 * 2.24 miles per hour
28.4 meters per second = 63.61 miles per hour.
Thus, the correct answer is - 63.61 miles per hour.
D. the ice changes to a liquid and the molecules in the water move faster
Answer:
Answer to the question as below
Explanation:
In all four H-R diagrams, first we look at the diagram which is at the left and it represents the Sun; it may be any other one solar mass star as a hydrogen burning main sequence star, with spectral type G and one solar luminosity.
In the next diagram it shows that the Sun after it has exhausted its core hydrogen and left the main sequence, making it a sub-giant with energy generated by hydrogen burning in a shell around an inert helium core.
Look into the third diagram which shows the Sun a little later; its energy source is still hydrogen shell burning, but at this point it has expanded in size so much that it is a red giant.
In the final diagram which is located at far right; it shows the white dwarf corpse of a one-solar-mass star; it is hot because it is the exposed core of the dead star, but dim because it is small in size.
Answer:
0.407 c
Explanation:
L₀ = Actual length of the spaceship lilac = 717 m
L = length of spaceship observed = 655 m
v = speed of lilac relative to earth
Using the equation
Inserting the values
v = 0.407 c
