A nonconducting rod of mass M and length l has a uniform charge per unit length l and rotates with angular velocity about an axis through one end perpendicular to the rod. The moment of inertia I =1/3*^2 a) Consider a small segment of the rod of length dx and charge dq = dx, at a distance x from the pivot. Provide the magnetic moment as a function of ,,, and .

b) Integrate the result from part (a) and provide the total magnetic moment of the rod as a function of ,, and, .

c) Show that the magnetic moment (m) and angular momentum (L) are related by expressing the magnetic moment as a function of Q (the total charge on the rod), M, and L.

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?

A2 kg ball travellng to the right with a speed of 4 m/s collidees with a 5 kg ball traveling to the left with a speed of 3 m/s. take right to be the positive direction. what is the total momentum of the two balls before they collide? what is the total momentum of the two balls after they collide?

The table below shows the acceleration of gravity on different bodies in the solar system. on which body would a 10 kg lamp has the most gravitational potential energy when lifted to a height of 2 m? a. earth b. mars c. neptune d. uranus
