Answer:
The skidding distance would be doubled
Explanation:
When the truck applies the brakes and slows down, its motion is a uniformly accelerated motion, so its skidding distance can be found by using the suvat equation
where
v = 0 is the final velocity (zero since the truck comes to a stop)
u is the initial velocity
a is the acceleration
s is the skidding distance
The acceleration can also be written as
where F is the force applied by the brakes and m the mass of the truck. Substituting into the previous equation,
We see that the skidding distance is proportional to the mass: therefore, if the mass of the truck is doubled, the skidding distance will double as well.
Thermal energy, creates steam or pressure, therefore, if in a small space it creates pressure within its "shell"
A change in pressure applied to an enclosed fluid is transmitted undiminished to every point of the fluid and to the walls of the container. This is a statement of Pascal's Principle, which is the basis of the hydraulic jack you see lift cars at the garage.
Answer: Decreases
Explanation:
By definition, absolute zero temperature defines the temperature at which the atoms of a material no longer transmit thermal energy.
Engineering materials can transmit thermal energy at higher temperatures by random molecular motion.
It follows that as the temperature decreases toward absolute zero, random molecular motion decreases.
