Assume the entire mass of a 10 kg wheel along its rim which is 50 cm from the axis of rotation (the wheel is considered a thin ring). The wheel is rotating at an angular speed of 20 rad/s. If the wheel is braked through the brake pads on the edge and stops 1 second later, the force exerted by the brake pads on the wheel is equal to​

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

answer; /// the above statement is (true);

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
