One kilogram is slightly more than a) 2 b) 5 u. s. pounds. c) 0.5 d) 1 11) the mass of a proton is 1.67 a) 1.67. 10-30 g b 10-27 kg.

The correct option is: a) 2 U.S. pounds;

B) 1.672622×10⁻²⁷ kg

Explanation

Pound is a United States customary unit for mass and is abbreviated as lb. One pound is defined as being equal to 0.45359237 kilograms (kg), exactly.

Kilogram is the SI unit of mass and is abbreviated as kg.

Since, 1 lb = 0.45359237 kg  

Therefore, 1 kg = 1 ÷ 0.45359237 lb ≈ 2.20462 lb

Therefore, we can say that 1 kilogram is slightly more than 2 pounds.

A proton is a positively charged subatomic particle, that possesses +1e electric charge and has mass approximately equal to 1.672622×10⁻²⁷ kg.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

i believe the answer is true.
