Answer:

Refraction are in parts or are reflected brokely, like light against aluminum. While a reflection, is exact. Like a mirror.

Answer:

reflection of sound and reflection of sound is different because reflection of sound is due to the reflection of sound,light which comes back by striking on a surface.

and refraction of sound is the bending of sound from one to another medium

hope it helps you. have a good day, please mark me as brain list. and sorry for the bad picture ☺️

Why is Pluto now called a dwarf planet
zvonat [6]
Before Pluto was discovered, it was predicted. Astronomers had observed that massive objects can affect the orbits of its neighbors, and, after seeing deviations in the orbits of Uranus and Neptune, assumed something substantial existed beyond their orbits.
When Pluto was spotted, it was thought to be the predicted object and was identified as a ninth planet.
A few decades later, astronomers started discovering more and more objects around other stars and didn’t know whether to call them planets or not. There appeared to be a need to define what a planet means, and that led to what some people consider Pluto’s demotion to a dwarf planet.
The International Astronomical Union decided that full-sized planets must orbit the sun, have a round shape, and have cleared their orbits of other objects. Pluto fulfills the first two criteria, but not the third.
It still goes around the sun, it’s round enough, it’s got moons, and behaves like a planet, but the idea is that Pluto did not form the same way as the rest of the planets. Pluto’s orbit is both eccentric and inclined more than the rest of the planets by about 17 degrees. That’s suggests something is different about this object.
This debate about whether to call it a planet or not is silly, because it doesn’t matter to Pluto what you call it. It is an interesting object, goes around the sun, and shows geology and an atmosphere.
There’s a tendency to define objects based on what they are now, but nothing is constant in the universe. There are some issues with the nomenclature, and a definition today may not apply to the same object tomorrow.

When a neutrally charged atom loses an electron to another atom, the result is the creation of
asambeis [7]
ionic compound. The atom that lost the electron becomes a cation, and the atom that gains an electron becomes an anion. The cation and anion bond together because they have opposite charges to form an ionic compound. The question may be looking for just cation or anion, though.

Starting from rest, a 88-kg firefighter slides down a fire pole. The average frictional force exerted on him by the pole has a m
Cloud [144]

Answer:h=7.22 m

Explanation:

Given

mass of firefighter m=88 kg

Frictional Force F=800 N

average speed at bottom v=3.2 m/s

Let h be the height of Pole

net force on Firefighter is

F_{net}=88\times 9.8-800=62.4

therefore net acceleration is

a_{net}=\frac{62.4}{88}=0.709 m/s^2

using v^2-u^2=2ah

here v=3.2 m/s

u=0

(3.2)^2-0=2\times 0.709\times h

h=\frac{10.24}{1.418}

h=7.22 m
