The figure shows a solid non-conducting sphere of radius R = 10 cm and total charge q distributed uniformly on it's volume. solve the following (assume k = 9x10° N. m?/c² and ɛg = 8.85x1012 c²/N. m²) a) If the E-field = 9×10° N/C at r = 20 cm, find the charge q on the sphere %3D b) Find the E-field at the surface of the sphere c) What is the flux through a spherical Gaussian surface (shown in figure) of radius r= 8 cm with it's center at the center of sphere​

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
