A box with a mass of 100.0 kg slides down a ramp with a 50 degree angle. What is the weight of the box?
981 N
What is the value of the normal force? Round the answer to the nearest whole number.

What is the acceleration of the box? (Disregard friction and air resistance.) Round the answer to the nearest tenth.

State one advantage and one disadvantage of using a plane mirrior as a driving mirrior

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

Aspecimen of oil having an initial volume of 580cm^3 is subjected to a pressure increase of 4.0 mpa, and the volume is found to decrease by 0.40 cm^3. (a) what is the bulk modulus of the material? (b) what is the compressibility of the material?
