The forces are net forces. I think this is correct.
ಠ_ಠ Hey, hang on.. you might've made a discovery. Nobody has tested it so how do we know? ಠ_ಠ
Answer:
Explanation:
The pressure of the gas can be found out as follows
Gas law formula is as follows
PV = nRT
P = nRT / V
= 32.4 X 8.31 X ( 273 + 459.38 ) / 51 X 10⁻⁶
3866.45 X 10⁶ Pa.
The first change is isobaric therefore
V₁ / T₁ = V₂ / T₂
V₂ = V₁ X T₂/ T₁
= 51 X 10⁻⁶ X ( 855.6 +273) / (459.38 +273)
= 78 X 10⁻⁶
78 cm³
After the first operation , the pressure of the gas remains at
= 3866.45 X 10⁶ Pa.
Now volume of the gas changes from 78 cm³ to 25.3 cm³ isothermally so
P₁V₁ = P₂V₂
P₂ = P₁V₁ / V₂
= 3866.45 X 10⁶ X 78 / 25.3
= 11920 X 10⁶ . Pa
Complete Question
A man on a road trip drives a car at different constant speeds over several legs of the trip. He drives for 55.0 min at 60.0 km/h, 18.0 min at 80.0 km/h, and 60.0 min at 60.0 km/h and spends
25.0 min eating lunch and buying gas
What is the total distance traveled over the entire trip (in km)
Answer:
The value is 
Explanation:
From the question we are told that
For 
the speed is 
For 
the speed is 
For 
the speed is 
The time taken to have lunch is 
Generally the total distance traveled over the entire trip (in km) is mathematically represented as
=> 
=> 
=>
The energy used in the process is used to rebound the ball to a certain height. The efficiency of the first rebound is equal 1.15/1.50 or 0.77. Hence the not used is the equal to the other part of the fraction where ball did not fully rebound to the original height. In this case, the equation is (1-0.77)^x = 1 - 0.93 where x is the number of rebounds until 93% of the energy is lost. x is equal to approx 10 rebounds.
