Answer:
The value is
Explanation:
From the question we are told that
The volume is
The initial pressure is
The initial temperature is
The final temperature is
Generally for an adiabatic process the workdone is mathematically represented as
Here is the internal energy of the system which is mathematically represented as
So
Generally from ideal gas equation we have that
Here R is the gas constant with value
So
=>
So
=>
Answer:
245 N
Explanation:
Force is given by mass × acceleration. The mass is given and we need to determine the acceleration.
The bobsled starts from rest; its initial velocity is 0.0 m/s. After a distance of 6.5 m, its speed is 7.0 m/s
We use the equation of motion:
<em>v</em> is the final velocity, is the initial velocity, <em>a</em> is the acceleration and <em>s</em> is the distance.
The net force is
Answer:
Hello There!
It is Speed.
Because in the question it is said that at which speed car is travelling.
Speed is a scalar quantity.
If it is velocity then first know this that it is a vector quantity.
It must include both magnitude and direction.
If it is velocity then it would be 40 mph east or west or north or south.
