Answer:
V = 1.1658 × V
Explanation:
given data
strip of copper thick = 130 µm
strip of copper wide = 4.40 mm
uniform magnetic field of magnitude B = 0.79 T
current i = 26 A
number of charge carriers per unit volume = 8.47 × electrons/m³
solution
we know that number density is express as
n = \frac{Bi}{Vle} ...............1
B is uniform magnetic field and i is current and V is hall potential difference and l is thickness and e is electron charge 1.6 × C
so V will be as
V = \frac{iB}{nle} .....................2
so put here value and we get V
V =
V = 1.1658 × V
Explanation:
Let
The Lorentz length contraction formula is given by
where L is the length measured by the moving observer and L' is the length measured by the stationary Earth-based observer. We can rewrite the above equation as
Taking the square of the equation, we get
or
Solving for v, we get
Answer:
Position.
Explanation:
Motion can be defined as a change in location with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement etc.
A complete description of your position includes a distance, direction, and reference point. Thus, this includes an object's distance in a certain direction from a reference point.
Answer:
Total time taken by boat to cover all the displacement = 452.3254 sec
Explanation:
We have given speed of boat = 4.72 m/sec
Speed of current flowing = 3.86 m./sec
In downstream relative speed of boat = speed of boat + speed of current flowing = 4.72+3.86 = 8.58 m/sec
Distance traveled downstream = 297 m
So time taken by boat to travel 297 m downstream
In upstream relative speed of speed = speed of boat - speed of current flowing = 4.72 -3.86 = 0.86 m/sec
Distance traveled in upstream = 389 m
So time taken to travel 289 m upstream
So total time
