Using charles law
v1/t1=v2/t2
v1=49ml
v2=74
t1=7+273=280k
t2=?
49/280=74/t2
0.175=74/t2  cross multiply
0.175t2=74
t2=74/0.175
t2=422k or 149celcius

Helga [31]

Answer:

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.
