Answer:
The current would be 0.12A
Explanation:
Well, the formula for electric current is
where i is current, q is charge and t is time. Then we have to calculate the charge. If we know that the charge of a proton is , then we calculate the charge of 1500 protons as it follows:
So the current for each square meter of Earth's surface is
Finally, knowing the surface of the Earth is 510065284702000 , we can calculate the total current
Answer:
40.25 V
Explanation:
Parameters given:
Initial magnetic field, B1 = 0.65 T
Final magnetic field, B2 = 0 T
Number of turns, N = 73
Radius of loop, r = 18 cm = 0.18 m
Time taken, Δt = 0.12 s
The magnitude of the EMF induced in a loop of wire due to a changing magnetic field is given as:
V = | [-N * A * (B2 - B1)] / Δt |
Where A = area of loop
Area of loop = πr²
Therefore, the magnitude of the EMF induced will be:
V = | [-N * πr² * (B2 - B1)] / Δt |
V = | [-73 * π * 0.18² * (0 - 0.65)] / 0.12 |
V = |40.25| V
V = 40.25 V
This is the magnitude of the EMF induced in the loop of wire.
Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes. ... One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury. Atmospheric pressure drops as altitude increases
If the group of all forces acting on an object is balanced,
then the effect of all of them is the same as if there were
no forces at all on the object. In that case, the object
continues moving in a straight line at a constant speed.
