9. A 70kg man weighs 686 Newtons on Earth. That man traveled to Planet X which has 5 times more gravity than Earth. What are his mass and weight on Planet X?
a. Mass = 350 kg and weight = 3,430 N
b. Mass = 70 kg and weight = 3,430 N
c. Mass = 350 kg and weight = 686 N
d. Mass = 70 kg and weight = 686 N

The a992 steel rod bc has a diameter of 50 mm and is used as a strut to support the beam. determine the maximum intensity w of the uniform distributed load that can be applied to the beam without risk of causing the strut to buckle. take f.s. = 2 against bucklin

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
