You and a friend are asked to draw the two-dimensional electric field line pattern for two charged objects located near each other. the charge on the first object is +2q (with q positive), and the charge on the second object is −q. you show 32 field lines emanating from the first charge and 16 field lines terminating on the second charge. your friend shows 24 field lines emanating from the first object and 12 terminating on the second object.

What is tan(61)? а. 1.80 b. 0.49 c. 0.61 d. 0.87

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
