Answer:
simple, Volt =change in potential energy/Charge
the unit of energy is newton meter (Force*distance)
the unit of charge is coloumb
So, Volt/meter=newton* meter/coloumb*meter
=newton/coloumb (hence proved)
This unit is the potential drop per unit of length in a conductive wire with uniform resistance
Answer:
Yes the student is correct
Explanation:
The first law of thermodynamics states that energy can neither be created nor destroyed
The second law of thermodynamics states that the entropy (disorderliness) of an isolated system always increases
Therefore, whereby energy is not supplied to maintain the orderly oscillatory motion with constant amplitude, the amplitude of the system is bound to reduce with time that is the vibration of the system must be damped
Answer:
In some situations, matter demonstrates wave behavior rather than particle behavior. This is best illustrated by which phenomenon is:
<u>C. Interference patterns of </u><u>electrons</u><u>.</u>
The correct answer is D. the star is getting farther away.
When the light has red-shifted, it shows that everything is moving away from a certain point. This is known as the Doppler effect and proves the Big Bang (which would be the center point that everything is moving away from). Just as a 'for your information', blue shift is when the star is moving towards us.
Hope I helped :)
