Ow this kimo treatment is hurting

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

Amira pulls a 3 pound wagon 4 feet. how much work has she done?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
