As seen from above, a playground carousel is rotating counterclockwise about its center on frictionless bearings. A person standing still on the ground grabs onto one of the bars on the carousel very close to its outer edge and climbs aboard. Thus, this person begins with an angular speed of zero and ends up with nonzero angular speed, which means that he underwent counterclockwise angular acceleration. The carousel has a radius of 1.50 m, an initial angular speed of 3.14 rad/s, and a moment of inertia of125 kgm2. The mass of the person is 48 kg. Find the final angular speed of the carousel after the person climbs aboard

The fringe width in a Young's double slit arrangement is 0.008cm. What could be the fringe width if the slit separation is halved and the screen slit distance is doubled?
When a physical property such as charge exists in discrete "packets" rather than in continuous amounts, the property is said to be: a) Discontinuous b) Abrupt c)
A parallel plate capacitor, each with plate area A and separation d, is charged to a potential dissimilarity V. The battery used to charge it is then disconnected. A dielectric sla
