Answer:

m v^2 / R = m g where gravitational force provides centripetal force

R = v^2 / g = 14.3^2 m/s / 9.8 m/s^2 = 20.9 m

Why is it important for car designers to keep accurate records of their experimental procedures
storchak [24]
Like all experiments, it's important to keep records of the their experiment procedures so future car designers and experimenters can compare and contrast their results from their experiment and improve their experiment accordingly. I'm pretty sure this is it. Stay cool my man.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by B. What is the magni
den301095 [7]

Answer:

Option C is correct.

The magnitude of the field is reduced to half at twice the distance,

Explanation:

The magnetic field produced in a long, straight conductor carrying a current I at distance r is given by

B = μ₀I/2πr

Where μ₀ is the constant permeability of free space.

If we increase the distance by twice then

B = μ₀I/2π(2r)

B = μ₀I/2πr(2)

B = B/2

Therefore, the magnitude of magnetic field is reduced by B/2 at twice the distance.
