Q1. The pulley system is used to lift a 52 kg crate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to crate. assume the masses of the chains, pulleys, and ropes are negligible, conclude the force, the tension in the upper chain, and the tension in the lower chain, given that crate is rising with an acceleration of 2.8 m/s^2.
Q2. What is the body temperature in degree Celsius, if you had a fever of 106.5 degrees in Fahrenheit, what will it being in Kelvin and Celsius degrees also? What formula should I use to answer the problem?
