Solve the attachment please What is the resultant of the following vectors? vector A = 4.5 at 198o
vector B = 4.2 at 64o
vector C = 3.9 at 266o
Arrange the vectors head-to-tail and carefully estimate or measure the magnitude and direction of the resultant.

Magnitude =

Direction =

How does the image distance (di) of a convex lens compare with the image distance of a concave lens? a. the image distance of the convex lens is positive, and that of the concave lens is negative. b. both are negative for a virtual image. c. both are positive for a virtual image d. the image distance of the convex lens is negative, and that of the concave lens is positive.

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

All the simple machines make work easier to do by changing the or of a force. a. size; type b. work; type c. size; direction d. type; direction
