Every substance has a specific value of heat required in order to change the temperature of 1 gram of the substance by 1 degree celsius. specific heat is calculated by using the equation q=mcδt, where q represents heat in joules, m represents mass in grams, δt is the change in temperature in celsius, and c is the coefficient constant for a substance. what are the units for thecoefficient c.
a. c=j·g·°c
b. c=j·g/°c.
c. c=j/g·°c
d. c=g·°c/j

Intro: a solid ball of radius rb has a uniform charge density ρ. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of ρ, rb, r, and ϵ0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of ρ, rb, r, and ϵ0. part c: let e(r) represent the electric field due to the charged ball throughout all of space. which of the following statements about the electric field are true? check all that apply. e(0) = 0 e(rb)=0 limr→∞e(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as r→∞.
