Abanked road comer of radius 146 m is to be constructed. if the comer is designed for vehicles moving with a speed of 20.0 m/s, what should the banking angle be, in units of degrees?

Angle of banking be 15.64 degrees.

Explanation:

It is given that,

Radius of banked road comer, r = 146 m

Velocity of vehicle, v = 20 m/s

Banking angle is defined as the angle at which a vehicle is in inclined position. Angle of banking is given by :

 , g = acceleration due to gravity

Where, = angle of banking

Hence, this is the required solution.

the answer is b

explanation:

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
