A star's brightness also depends on its proximity to us. The more distant an object is, the dimmer it appears. Therefore, if two stars have the same level of brightness, but one is farther away, the closer star will appear brighter than the more distant star - even though they are equally bright!
Here is a picture of my work. It's easier than typing it out!
The answer is true a convex lens can produce a real image but not a viral image
Answer:
Explanation:
The Work-Kinetic Energy Theorem states that the work done on a particle of mass "m", equals the particle's change in Kinetic Energy (final Kinetic Energy of the particle "" minus the initial Kinetic energy of the particle ""), and it is expressed as:
where we have used the explicit form of the KE of a particle of mass m and velocity . Of course, stands for the final velocity of the particle, and for the particle's initial velocity.
