4. A 1300 kg car makes a turn with a 45 m radius. Coefficient of static

Physics
1 answer:
asambeis [7]3 years ago

Answer: v = 11 m/s

Explanation:

If we ASSUME that the road is horizontal, not banked

The maximum friction force available is μmg

This will need to supply all of the required centripetal force

mv²/R = μmg

v = √(μgR) = √(0.28(9.8)(45)) = 11.1121...≈ 11 m/s

A4) A straight wire that is 0.60 m long is carrying a current of 2.0 A. It is placed in a uniform magnetic field of strength 0.3
Klio2033 [76]

Answer:

\theta=30^{\circ}

Explanation:

It is given that,

Length of the wire, L = 0.6 m

Current flowing inside the wire, I = 2 A

Uniform magnetic field, B = 0.3 T

Force experienced by the wire in the magnetic field, F = 0.18 N

To find,

The angle made by the wire with the magnetic field.

Solve,

We know that the magnetic force acting on the wire inside the magnetic field is given by :

F=ILB\ sin\theta

sin\theta=\dfrac{F}{ILB}

sin\theta=\dfrac{0.18}{2\times 0.6\times 0.3}

\theta=30^{\circ}

Therefore, the wire makes an angle of 30 degrees with respect to magnetic field.
