Answer:
Two Neutral
Explanation:
If; One postive, and one negative they would be attracked. >-<
If; one postive and the other was postive, (or vice versa) they would repel <->
they both have an electrical charge, and force.
Neutral's are Nueatral. they have to opisition or attraction= No electrical force.
The amount of a radioactive element over time can be written as:
So, considering that we know the time of its half life, we know how long it takes to get to half the original amount. This is (usint the amount of days in microseconds):
Thus, lambda=3.82*10^(-11)/microseconds
Answer:
F = 0.332 N in the east direction
Explanation:
Length, L = 7.7 cm = 7.7 * 0.01 = 0.077 m(along the north south)
Current, I = 3.45 A (northwards)
Magnetic field, B = 1.25 T (vertically upwards)
The magnitude of the force is given by, F = ILBsin90
F = 3.45 * 0.077 * 1.25 * 1
F = 0.332 N
The direction of the force is calculated using the Right Hand Thumb Rule:
It states that "Hold the wire carrying current in your right hand so that the thumb points along the wire in the direction of the current, then the fingers will encircle the wire in the direction of the lines of magnetic force."
Based on the Right Hand Thumb Rule, the magnetic force will act in the east direction
