A human hair is approximately 57 um in di-

ameter.

Express this diameter in meters.

Answer in units of m.

In a one electron system, the probability of finding the electron within a shell of thickness δr at a radius of r from the nucleus is given by the radial distribution function p (r) = r2r2 (r).

In Example 10.1 (p. 234), if the pebble was instead launched at a 45 degree angle above the horizontal, how would the total mechanical energy of the system change compared to when the pebble was launched directly upwards?

Suppose mass and radius of the planet are half and twice that of earth's respectively. If acceleration due to gravity of the earth is 10m/S2. Find acceleration due to gravity of that period

What is the kinetic energy of a 1.40 kg discus with a speed of 22.5 m/s?

What is the difference between a universal law and a scientific theory? A) Universal laws change as new evidence comes to light. Scientific theories never change. B) Scientific theories apply everywhere all the time. Universal laws do not.

A train departs from its station at a constant acceleration of 5m/s2. What is the speed of the train at the end of 20 seconds

What causes magnetism inside the atom?

Another machine uses aninput force of 200 newtons to produce an output force of 80 newtons

An empty capacitor is connected to a 12.0 V battery and charged up. The capacitor is then disconnected from the battery, and a slab of dielectric material (dielectric constant "k" = 2.8) is inserted between the plates.

how long can you afford to stop for lunch if you can drive a steady 90 km/h on the highway and must take a 225 km trip in 210 min?
