What is solid matter and can we covert matter into something else

1 answer:

6 0

Answer: Solid matter is one of the three main states of matter, along with liquid and gas. Matter is the "stuff" of the universe, the atoms, molecules and ions that make up all physical substances. In a solid, these particles are packed closely together and are not free to move about within the substance.

All matter exists as solids, liquids, or gases. These are called the states of matter. Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid).

A force of 25 newtons moves a box a distance of 4 meters in 5 seconds.

Simora [160]

By definition, we have that the work done is given by:

$W = F * d$

Where,

F: force in the direction of displacement

d: displaced distance

Substituting values we have:

$W = (25) * (4)\\W = 100 Nm$

Then, the power is given by:

$P = \frac{W}{t}$

Where,

t: time

Substituting values we have:

$P = \frac{100}{5}$

$P = 20\frac{Nm}{s}$

Answer:

The work done on the box is 100 Nm, and the power is 20 Nm/s.

Andreyy89

Answer:

Explanation:

Tellurium is the element of the periodic table with atomic number 52.

The atomic number of a chemical element represents the number of atoms contained in the nucleus of the atom: therefore, this means that an atom of tellurium contains exactly 52 protons in its nucleus.

Tellurium is classified as a metalloid, having properties in between metals and non-metals, and it appears with a silver color.

A pursuit spacecraft from the planet Tatooine is attempting to catch up with a Trade Federation cruiser. As measured by an obser

Ede4ka [16]

Answer:

0.384c

Explanation:

To find the speed of the pursuit ship relative to the cruiser you use the following relativistic equation:

$u'=\frac{u-v}{1-\frac{uv}{c^2}}$

u': relative speed

u: speed of the pursuit ship = 0.8c

v: speed of the cruiser = 0.6c

c: speed of light

You replace the values of the parameters to obtain u':

$u'=\frac{0.8c-0.6c}{1-\frac{(0.6c)(0.8c)}{c^2}}=0.384c$

Hence, the relative speed is 0.384c
