A certain material has a mass of 565 g while occupying 50 cm3 of space. What is this material?

Answers

Answer 1

Answer:

Answer:

Lead

Explanation:

To get the density of the material, the formula would be:

mass divided by volume which is given by $d = \frac { m } { v }$ .

Here in this problem, we are given a mass of $565 g$ which occupies a volume of $50 cm^3$ .

So plugging the data in the above formula to find the density:

Density = $\frac { 565 } { 50 } = 11.3$

From the table, we can see that the material is Lead which has a density of 11.3c/cm^3.

We know velocity of sound v=a₩(omega), but speed does not depend on amplitude, why?

Answers

The amplitude of a wave does not affect the speed at which the wave travels. The speed of a wave is only altered by alterations in the properties of the medium through which it travels.
Here’s some fun facts:
The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound.

In which of these materials does sound travel most slowly air,steel,glass,water

Answers

Sound travels the slowest through air, and the fastest through steel. This seems counter-intuitive, since sound seems clearer through air than it does through a solid like steel, but there is reasoning behind it. Since steel is a solid, the particles within it are more closely packed than in a liquid like water or the gases in air, in which the particles are farther apart even than the water. Sound waves don't have as much distance to travel between particles in solids as they do in liquids or gases, in which the particles are farther apart. Because of this, the sound waves can travel the quickest through solids. The only reason sound travels more quickly through steel than glass is because steel is a crystalline solid, while glass is an amorphous solid. Without getting into the specifics, the difference between a crystalline and an amorphous solid is that an amorphous solid's particles are farther apart than a crystalline solid's, which is why glass doesn't keep its shape as well as steel does. Because of this, sound travels more quickly through steel.

So, to recap, sound travels through air, steel, glass, and water in the following order, with 1 being the slowest and 4 being the quickest:
1. air
2. water
3. glass
4. steel

The one is air.It is air because you dont feel the air and sometimes it moves slowly

Explain how plants and algae use sunlight. how is this process important to other living things in an ecosystem ?

Answers

Plants and algae use sunlight to make food. They do this with the process of photosynthesis, and they create excess oxygen as a waste product. The oxygen is vital for other living organisms to survive and perform their daily functions. Hope this helps :)
