Two curves on a highway have the same radii. However, one is unbanked and the other is banked at an angle ?. A car can safely travel along the unbanked curve at a maximum speed v0 under conditions when the coefficient of static friction between the tires and the road is 0.980. The banked curve is frictionless, and the car can negotiate it at the same speed v0. Find the angle of the banked curve.
Unpolarized light passes through two polarizers in turn with polarization axes at 33° to one another. What is the fraction of the incident light intensity that is transmitted
What is the charge q. suppose the speed of sound in air to be 343 m/s.
Heat is extracted from a certain quantity of steam at 100 degrees celsius. Thus the steam changes into ice at 0 degrees celsius. If this energy were used to accelerate the ice from rest, what would be the linear speed of the ice.
The electric field in a region of space is oriented along the positive y axis. A circle of radius R is placed in xz-plane. The flux of the electric field by this circle is Φ. The same electric field passing through a second circle of radius 2R parall..
