Answer:
We need about 8769 meters of wire to produce a 2.6 kilogauss magnetic field.
Explanation:
Recall the formula for the magnetic field produced by a solenoid of length L. N turns, and running a current I:
So, in our case, where B = 2.6 KG = 0.26 Tesla; I is 3 amperes, and L = 0.57 m, we can find what is the number of turns needed;
Therefore we need about 39312 turns of wire. Considering that each turn must have a length of 
, where D is the diameter of the plastic cylindrical tube, then the total length of the wire must be:
We can round it to about 8769 meters.
Rest - it is the state in which body doesn’t move from it’s place
motion - it is the state in which body moves from it’s place
Because they are different they all show different traits.
Answer:
Net Force = 10N
Acceleration = 2m/s^2
Explanation:
calculate the net force and the acceleration on the block
Net force on the block F = mass * acceleration
Net force acting in the positive direction = 4N + 6N = 10N
Mass = 5kg
According to newton's second law;
a = F/m
a = 10N/5
a = 2m/s^2
hence the acceleration on the block is 2m/s^2
