Calculate the acceleration of gravity as a function of depth in the earth (assume it is a sphere). You may use an average density from the attached density profile for a spherical shell (which does not have to be very thin, for example, a shell from the inner core-outer core boundary to the middle depth of the outer core). Do not make the shell contains a large density contrast. Calculate enough points to make the g profile. Note that only the mass at radius less than r contributes to the gravitational acceleration. (15 points)

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.

Consider lifting a box of mass m to a height h using two different methods: lifting the box directly or lifting the box using a pulley (as in the previous part). what is wd/wp, the ratio of the work done lifting the box directly to the work done lifting the box with a pulley?
