Answer: Option (A) is the correct answer.
Explanation:
An isothermal process is defined as the process in which temperature of a system remains constant. In an isthermal process, = 0.
When an outside thermal reservoir is in contact with a system then very slow change in the system will occur in order to allow the system to continue adjusting to the reservoir's temperature through exchange of heat.
Hence, we can conclude that the temperature remains constant, best describes the isothermal process.
Answer:
-0.912 m/s
Explanation:
When the package is thrown out, momentum is conserved. The total momentum after is the same as the total momentum before, which is 0, since the boat was initially at rest.
where are the mass of the child, the boat and the package, respectively.
are the velocity of the package and the boat after throwing.
