tatuchka [14]

Voltage=V=5V
Current=I=25mA=25×10^-3A
Resistance be R

Apply ohms law

$\\ \rm\hookrightarrow R=\dfrac{V}{I}$

$\\ \rm\hookrightarrow R=\dfrac{5}{25\times 10^{-3}}$

$\\ \rm\hookrightarrow R=0.2\times 10^{-3}$

$\\ \rm\hookrightarrow R=0.0002\Omega$

A cube made Of an unknown material has a height of 9 symeters the mass of this cube is 3645 g. calculate the density of this cub

kherson [118]

Answer: $5 \frac{g}{cm^{3}}$

Explanation:

The density $\rho$ of a material is given by:

$\rho=\frac{m}{V}$ (1)

Where:

$m=3645 g$ is the mass of the cube

$V$ is the volume of the cube

Now, the volume of a cube is equal to the length $L$ of its edge to the power of 3:

$V=L^{3}$ (2)

If we know $L=9 cm$ , the volume of this cube is:

$V=(9 cm)^{3}=729 cm^{3}$ (3)

Substituting (3) in (1):

$\rho=\frac{3645 g}{729 cm^{3}}$ (4)

$\rho=5 \frac{g}{cm^{3}}$ This is the density of the cube

Who conducted the study?

Explanation:

One good question to ask the toothpaste making company is who conducted the study?

A company making toothpaste claiming a scientific study revealed that their toothpaste makes the mouth five times cleaner must have introduced a bias in this finding.

For a scientific study to be accepted and substantiated, it must have been tested and repeated by other scientists.
If no other scientist confirms this, then there is an obvious bias in the claim and it is not scientific.
