We don't have enough information in the picture to answer that question.
The disembodied right hand could just as well grab the wire in the other direction, with the thumb pointing to the right.
Maybe if we knew WHY the hand is holding the wire in this direction, and what other electrical phenomenon may be involved, we might be able to say something about the current in the wire.
(Actually, we don't even know if it's a wire. It might be a soda straw, a coat hanger, or a pool cue.)
Answer:
net force would be 50 N right
Explanation:
Answer:
0.39 m/s²
Explanation:
From the question,
a = v²/r.................... Equation 1
Where v = velocity, r = radius.
Given: v = 222 mi/h = (222×0.44704) m/s = 9.83 m/s, r = 820 ft = (820×0.3048) m = 249.94 m.
Substitute thses values into equation 1
a = 9.83²/249.94
a = 96.63/249.94
a = 0.39 m/s²
Hence the acceleration is 0.39 m/s²
It takes about 24 hours for a sperm cell to fertilize an egg. When the sperm penetrates the egg, the surface of the egg changes so that no other sperm can enter. At the moment of fertilization, the baby's genetic makeup is complete, including whether it's a boy or girl.

Answer:
The magnitude of electric force on object B due to object A when they are 2r distance apart is F/4.
Explanation:
Given :
Electric charge on object A = +Q
Electric charge on object B = +4Q
When the objects A and B are r distance apart, the magnitude of electrostatic force exerted on B due to A is given by the relation :
.....(1)
Now, the two objects are apart by distance of 2r, hence the force acting on the object B due to A is :
Substitute equation (1) in the above equation.
