If a particle with a charge of +3.3 × 10−18 C is attracted to another particle by a force of 2.5 × 10−8 N, what is the magnitude of the electric field at this location? A 8.3 × 10−26 NC
B 1.8 × 1010 NC
C 1.3 × 10−10 N/C
D 7.6 × 109 N/C

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to

Which of these activities increases the amount of carbon in the atmosphere?
