Charge is distributed within a solid sphere of radius r0 in such a way that the charge density is a function of the radial position within the sphere of the form: rhoe(r)=rho0rr0. part a if the total charge within the sphere is q (and positive), what is the magnitude of the electric field everywhere within the sphere in terms of q, r0, and the radial position r?

Your target variable is δf, the magnitude of the difference in frequency between the waves emitted from the sonar device and the waves received by the device after reflecting off the whale. write an expression for δf in terms of the relevant frequencies using the subscript notation introduced above.

An architect plans to use solar energy to heat the next house he designs. what principle of absorption and infrared energy can be applied to the design of the new house? how could she apply to those principals?

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
