Answer:
a = w² r
Explanation:
In this exercise, indicate that the wheel has angular velocity w, the worm experiences the same angular velocity if it does not move, and has an acceleration towards the center of the circle, according to Newton's second law, called the centripetal acceleration.
a = v² / r
angular and linear variables are related
v = w r
we substitute
a = w² r
where r is the radius of the wheel
Answer:
Therefore, the distance between object and image is given by the distance between object and mirror + distance between mirror and image = 0.5 m + 0.5 m = 1 m. 4. You are provided with a concave mirror, a convex mirror, a concave lens and a convex lens. To obtain an enlarged image of an object you can use either (a) concave mirror or convex mirror.
Explanation:
The paper clip did because it is a conductor. A pencil is made with wood and that is an insulator.
