If two 50-N weights are attached to the opposite ends of a spring scale, and allowed to hang off the sides of the table upon which the spring scale rests, what is the tension
force on the spring scale in Newtons? (what is the reading on the scale?)
O a. Tension = 50 N
O b. Tension = 200 N
O c. Tension = 100 N
O d. Tension = ON

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?
