Answer:
Part b

Explanation:
Part a)
Let the radius of the coil is R and magnetic field on its axis is given as

now we know that two coils are identical and we need to find magnetic field between two coils
so we will have net magnetic field given as

Now we know that magnetic field is maximum at position

so we will have


so it will be at mid point of two coils
Part b)
Now we know that

so we will have

now magnetic field is given as

put z = 0.5 R

Animals' nails are called claws, unless it is a bird
most animal nails are called claws
bird nails are called talons
Answer:I think its the first one
Explanation:
Answer:
D: a buoy bobbing up and down in place with ocean waves
Explanation:
To solve this problem we will use the relationship given between the centripetal Force and the Force caused by the weight, with respect to the horizontal and vertical components of the total tension given.
The tension in the vertical plane will be equivalent to the centripetal force therefore

Here,
m = mass
v = Velocity
r = Radius
The tension in the horizontal plane will be subject to the action of the weight, therefore

Matching both expressions with respect to the tension we will have to


Then we have that,


Rearranging to find the velocity we have that

The value of the angle is 14.5°, the acceleration (g) is 9.8m/s^2 and the radius is



Replacing we have that


Therefore the speed of each seat is 4.492m/s
