Answer:
4 A
Explanation:
V = IR, where V=voltage, I=current, R=resistance. This is Ohm's Law. (remember that for units V = volts, Ω = ohms, A = amperes.)
V = IR
12 V = I * 3 Ω
12/3 = I
<u>I = 4 A</u>
Answer:
The bikers speed at the top of other hill is <u>25.82 m/s.</u>
Explanation:
Considering the biker is riding on a frictionless surface.
∴ There is no non-conservative or external force acting on the biker.
Hence we can conserve the energy of biker and bike as a system.
Let,
= 44m
= 10m
Since the biker starts from rest , his initial speed
= 0 m/s
Let final speed of the bike at the top of other hill be
.
∴ Initial Energy (at the top of 44m hill) = 
Final Energy (at the top of 10m hill) =
.
Conserving both the energies , we get
= 
∴ 
Substituting the values for g ,
,
, we get
= 25.82 m/s
Sure why not I'll sub your channel
This is a true fact.
Example: An object sitting still in place has energy called potential energy so if an object moving, kinetic energy, and pushes the other object not moving, then the potential energy object will now have kinetic energy; Change.
So, that IS a true fact.
I hope this helped!
