Answer:
I would say d sry if im wrong
Explanation:
A vector quantity is defined by magnitude and direction. For example, we might say that a car has an average speed of 25 miles per hour. Its average velocity might be 25 miles per hour due east.
Answer:
v₂ = 48 mph
Explanation:
We know that,
Speed = distance/time
A German Shepherd takes 4 hours to cover a distance, if it travels at a speed of 36mph.
We need to find the speed to cover the same distance in 3 hours.
So, the new speed is 48 mph.
Isothermal process<span> is a </span>change<span> of a </span>system<span>, in which the </span>temperature<span> remains constant: Δ</span>T<span> = 0. So, if the thermodynamic process takes place at a constant temperature so that the internal energy of a system remains unchanged than this process is isothermal.
</span><span>The Joule's second Law states that the internal energy of a fixed amount of an ideal gas depends only on its temperature. So, isothermal processes are of great interest for ideal gasses.</span>
