So we need to find the formula for magnetic field B using the current (I) and the distance from the probe (d). So, We know that the stronger the current I, the stronger the magnetic field B. That tells us that the I and B are proportional. Also we know that the strength of the magnetic field B is weaker as the distance d of the probe increases. That tells us that B and d are inversely proportional. So our formula should have B=(I/d)*c where c is a constant of proportionality. c=μ₀/2π where μ₀ is the permeability of free space. So finally our formula is B=(μ₀I)/(2πd).
Possibilities . . .
-- nuclear reaction
-- nuclear fission
-- nuclear fusion
-- radioactive decay.
Any of these makes it a true statement.
Density is the mass of a substance per unit volume.
Answer:
Protons, Electrons, and neutrons
Answer:
The correct option is "In order to gain more power you would need to increase either current or voltage."
Explanation:
To answer the question, we note that;
The formula for Electrical Power are as follows,
P = I²·R, or P = I·V,
Therefore, if we increase either the current, I with the voltage, V remaining constant or we increase the Voltage, V with the current, I remaining constant or we increase both the voltage, V an the current, I the Power, P will be increased.
Therefore, the correct option is "In order to gain more power you would need to increase either current or voltage."
