In physics, spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold. Spacetime diagrams can be used to visualize relativistic effects, such as why different observers perceive where and when events occur differently.
Answer:
Given:
radius of the coil, R = 6 cm = 0.06 m
current in the coil, I = 2.65 A
Magnetic field at the center, B = 
Solution:
To find the number of turns, N, we use the given formula:
Therefore,
N = 22.74 = 23 turns (approx)
<span>The metric
system is the oldest name for the international system of units. The answer is <u>a.
True. </u>SI unit or the international systems of units are based on seven
basic units; the meter, kilogram, second, ampere, Kelvin, candela and mole. All
of these basic units are divided into multiples by a power of ten. For example
in meters, 1 meter is equal to: 1000 millimeter, 100 centimeter, 10 decimeter,
0.1 decameter, 0.01 hectometer, 0.001 kilometer and so on and so forth.</span>
