When you drive a car around a curve that is not banked, what force provides the centripetal acceleration? HINT: Think about turn
ing a curve on ice. If the curve is banked, what additional force plays a role in providing the centripetal force? Draw force diagrams to clarify your thinking.
2 answers:
Explanation:
When you drive a car around a curve that is not banked, the frictional force between the tyres of the car and the road provides the centripetal acceleration and the centripetal force. Figure A shows the force acting on the object in unbanked road.
Figure B shows the banked curve. In this type of curve, the horizontal component of the normal force is balanced by the centripetal force as well as centripetal acceleration.

Answer:
The possible thickness of the soap bubble =
Explanation:
<u>Given:</u>
- Refractive index of the soap bubble,
- Wavelength of the light taken,
Let the thickness of the soap bubble be .
It is given that the soap bubble appears very bright, it means, there is a constructive interference takes place.
For the constructive interference of light through a thin film ( soap bubble), the condition of constructive interference is given as:
where is the order of constructive interference.
Since the soap bubble is appearing very bright, the order should be 0, as order interference has maximum intensity.
Thus,
It is the possible thickness of the soap bubble.
