Two charges, q1 and q2, are at rest near a positive test charge, q, of
7.2.x 10^-6C. The first charge, q1 is a positive charge of 3.6 x 10'^-6C, located
0.025 m away from q at 35 degrees; q2, is a negative charge of -6.6 x 10^-6C
located 0.068 m away at 125 degrees.
a. Determine the magnitude of each of the forces acting on q.
b. Sketch a force diagram.
c. Graphically determine the resultant force acting on q.

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

If gases like carbon dioxide and methane make up less than 1% of the total atmosphere, why is it important for scientists to monitor changes in percentages of these gases?

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination. at the turning point, how far is the second student from the destination?
