Answer: The correct option is b.
Explanation:
The second law of the thermodynamics states that thermal energy can flow from the colder objects to hotter objects.
It is not possible to transfer heat from the colder body to hotter body without any work.
Energy will not flow spontaneously from the object at low temperature to an object at higher temperature.
Therefore, the correct option is b.
Answer:
404.4 m
Explanation:
Converting the initial speed from km/h to m/s then
The acceleration is resolved as shown in the figure hence
deceleration of the truck along the inclined plane will be
where g is acceleration due to gravity
Substituting g with then
Using kinematic equation
and making s the subject then
where v and u are final and initial velocities respectively
Substituting 0 for v, 38.89 m/s for u and then
Answer:
Asteroids
Explanation:
Asteroids are the small and large block of rocks that are found to be scattering space. There are numerous asteroids present in the asteroid belt which is located between the planet of Mars and Jupiter. These range from a few meters to hundreds of kilometers. They move so rapidly, at about 80,000 km/hr and there occurs constant collision with one another. These asteroids sometimes enter into the atmosphere of earth, which can cause a great mass extinction event.
These are believed to be the remnants particles that are present in space right after the formation of the solar system.
