Answer:

<h2>6 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 36 g

volume = 6 cm³

We have

$density = \frac{36}{6} = 6 \\$

We have the final answer as

<h3>6 g/cm³</h3>

Hope this helps you

Alex Ar [27]

Answer:

the portion of electromagnetic spectrum is occupied by signal is called bandwidth

Explanation:

Bandwidth is the part of electromagnetic spectrum which is occupied by the signal. It is also called as the range of frequency over which the receiver or any other electronic circuit works. Bandwidth is the amount of the data been transmitted from one point to other within the network in the specific amount of the time. It is expressed as the bit rate and are measured as bits per seconds (bps). Bandwidth is the sum of the connections.

Elephants can communicate over distances as far as 6 km by using very low-frequency sound waves. What is the wavelength of a 10

harkovskaia [24]

The characteristics of the sound waves allow to find the result for the wavelength is:

λ = 34.29 m

The sound wave is a longitudinal traveling wave, where the speed of the wave depends on the air temperature.

v = $v_o \sqrt{1 + \frac{T}{273} }$

where v₀ is the speed of sound for T = 0ºc v₀ = 331 m / s.

indicate that the temperature is T = 20ºC, let's find the speed of the traveling wave.

v = 331 $\sqrt{1 + \frac{20}{273} }$

v = 342.9 m / s

The speed of sound is related to wavelength and frequency.

v = λ f

λ = $\frac{v}{f}$

Let's calculate

$\lambda = \frac{342.29}{10}$

λ = 34.29 m

In conclusion using the characteristics of sound waves we can find the result for the wavelength is:

λ = 34.29 m

Gold has a specific heat of 0.130 J/g*C. If 195 joules of heat are added to 15 grams of gold how much does the temperature of th

Anna71 [15]

The correct answer to the question is : $100\ ^0C$

EXPLANATION :

As per the question, the specific heat of gold is given as c = $0.130\ J/g^0C$

The heat given to the gold dQ = 195 J

The mass of the gold is given as m = 15 gram.

We are asked to calculate the change in temperature.

Let the change in temperature is dT.

We know that dQ = mcdT

$dT=\ \frac{dQ}{mc}$

$=\ \frac{195}{15\times 0.130}$

$=\ 100\ ^0C$ [ANS]

Hence, the change in temperature is 100 degree celsius.
