The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure.
Answer:
35 N to the right
Explanation:
When calculating net force when both forces are on the same side you add them when they are going against each other you subtract them.
Evaporation - Heating
Condensation - Cooling
Freezing - Cooling
Melting - Heating
Sublimation - Heating
Deposition - Cooling
Answer:
Explanation:
Let the velocity of car and truck be u and breaking acceleration be a .
We shall have to assume the reflex time of the driver of the car . By the time he applies brake , his car will cover some distance . There will be some time tag between the time the truck starts decelerating and the driver of the car responding to that . During this period the car will not start decelerating . It will keep on moving with uniform velocity of u .
Let this time lag be t .
b )
For answer see the attached file
c )
The minimum trailing distance will be the distance covered by car before it starts decelerating in response to truck's deceleration .
minimum trailing distance d = u x t
d ) u = 80 km / h = 22.22 m /s
reflex action time t = 0.1 s ( assumed time )
d = 22.22 x .1
= 2.2 m
