A 11 kg mass is pulled up with a 40 N and SO N force, right with a 30 N and 4 points 35 N force, down with a 60 N and 20 N force, and left with a 50 N and a 20
N force. What is the acceleration of the mass?

Gunpowder residue is most likely to show up where on a shooters hands

Infrared rays have a shorter wavelength than question 11 options: x-rays. ultraviolet rays. radio waves. gamma rays.

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
