A nonconducting charged slab 1 of thickness 2a has a nonuniform but symmetrical volume charge density rho0x/a, rho0>0. The sheet is centered, at x=0, on the yz-plane of a Cartesian coordinate system.
Determine the magnitude of the electric field in the region [−a < x < a] as a function of x, the distance from the yz-plane. Express your answer in terms of the variables rho0, a, x, and the permittivity constant ϵ0.

Asmall 21 kilogram canoe is floating downriver at a speed of 1 m/s. what is the canoe's kinetic energy?

Match each vocabulary term to its definition. 1. electrons neutral subatomic particles found in the nucleus of the atom 2. neutron lowest energy position of an electron in an atom 3. photon the path of an electron around the nucleus of an atom 4. ground state negatively charged, subatomic particles 5. protons packet of energy of specific size 6. element substance with only one type of atom 7. orbital positively charged, subatomic particles found in the nucleus of the atom

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
