How is the production of thyroid hormone effected in a  healthy animal exposed to cold temperatures?

How much work is required to bring in a 3.8 uC point charge from far away and place it a distance of 0.20 m away from a 10 uC point charge?

A 4.5 u C point charge is released from rest in a uniform electric field of magnitude 1.47 x 10^4 N/C.  The mass of the charge is 2.8 x 10^-4 kg and the electric force is the only force present.  Find the speed of the charge when it has moved a distance of 0.65 m in this field.

A charge of -3.0 uC (10^-6 C) is experiencing an electric force of 1.20 N from a 6.5 uC charge.  How far apart are these charges?

A 3.67 uC point charge gains 1.6 J of potential energy when it moves between two points in an electric field.  What is the potential difference between these two points?

A 4.1 uC charge is placed in an electric field and, as a result, experiences an acceleration of 215 m/s^2.  If the mass of the charge is 1.2 x 10^-4 kg, find the magnitude of the electric field.  Assume that the electric force is the only force present.

The fear of eight-legged arthropods including ticks and spiders is known as _____________.

From the class readings, much of the mortality of malaria in endemic areas is concentrated among children over the age of five. 

A football is kicked with a speed of 15.0 m/s at an angle of 40 degrees above the horizontal.  The ball is kicked over level ground.  How far (horizontal distance) does the ball travel?

For the vectors shown below:  A = 25 m, B = 70 m, and C = 35 m.  Find the direction (relative to positive x-axis) of the resultant of the three vectors.
