Explanation:
Answer: 44.37 degrees C
Explanation:
Use combined gas law: (P1)(V1)/T1=(P2)(V2)/T2
For most gas laws, you must convert to Kelvin:
K=deg C+273
K=25+273=298 K
Plug and chug:
(1.0 atm)(1.2 L)/(298 K)=(0.71 atm)(1.8 L)/(x)
Solve for x and get 317.37 K
Subtract 273 from this to convert to degrees Celsius. You will get 44.37 degrees Celsius.

Answer:
16.6 km/h
Step-by-step explanation:
Speed = distance/time
= 400.0 m/86.8 s
= 4.608 m/s Convert kilometres to metres
Speed = 4.608m/s × (1 km/1000 m)
= 0.004 608 km/s Convert seconds to hours
Speed = 0.004 608 km/s × (3600 s/1 h)
= 16.6 km/h
Answer:
The athlete should consume about 476 g of carbohydrates per day to maintain a good storage of glycogen in his body
Explanation:
For an athlete who trains daily, 5 to 7 g of carbohydrates per Kg of body weight per day is recommended;
∴ m athlete = (175 Lb)×(0.453592 Kg/Lb) = 79.3787 Kg
⇒ m carbohydrate = (79.3787 Kg)×( 6 g carbohydrate/ Kg.day) = 476.27 g carbohydrate/day
