Answer:
It's solar because if you leave a tv on for longer it gets hot and obviously it produces light and sound so, by subject of elimination, it's solar.
Explanation:
Answer:
The objects will stick together and move with common final velocity.
Explanation:
In an isolated system, there are no external forces acting on the object. Let there are two objects say object A and B. It is supposed that an isolated system in which two objects about to collide have equal and opposite momenta.
In an inelastic collision, the momentum of the objects after the collision remains while the kinetic energy is not conserved. Some of the energy is lost. After the collision, the objects will stick together and move with one common velocity.
Hence, the correct option is (b) "The objects will stick together and move with common final velocity".
Answer and explanation:
Let be the velocity of a body projected vertically up, 1 second before it reaches its maximum height. We know, from the kinematics equations, that the distance traveled in an interval of time is equal to:
Then, in the last second, the distance traveled is equal to:
But the velocity is related to the time by the equation:
And substituting this expression in the equation above, we obtain:
It means that the distance traveled by the body in the last second of its motion is a constant, independent of its initial velocity.
Answer:
Answer is A) Fermi
Explanation:
Fermi is the expressive unit for nuclear sizes. Fermi = 10^-15 meter.
