Enlarged real image.
A converging lens always has a positive focal point so the light rays always converge on the real side of the lens, creating a real image.
It will also be enlarged because when you draw a ray diagram you can see that the image will be about two times or so larger depending on where the position of the object actually is. Usually when an image is reduced, it is when it is a diverging / concave lens.
Explanation:
to overcome the repulsion between the protons in the nuclei that join
Wavelength = (speed) / (frequency) = (460 m/s) / (230/sec) = <em>2 meters</em>
Answer:
An estuary is the area where a river meets the sea or ocean, where fresh water from the river meets salt water from the sea.
Answer:
8 J and 2 J
Explanation:
Given that,
Mass of the rubber ball, m = 1 kg
Initial speed of the rubber ball, u = 4 m/s (in east)
Final speed of the rubber ball, v = -2 m/s (in west)
We need to find the kinetic energy of the ball before it hits the wall, the kinetic energy of the ball after it bounces off the wall.
Initial kinetic energy,
Final kinetic energy,
So, the initial kinetic energy is 8 J and the final kinetic energy is 2 J.
