Complete Question

The complete question is shown on the first uploaded image  

Answer:

The  value  is  S_g_2  =  3.128

Explanation:

From the question we are told that  

  The specific gravity of the first fluid  is  S_g_1 =  14.5

  The  pressure of air is  P_a  =  81kPa  =  81*10^{3} \  Pa

  The  atmospheric pressure is  P_A  =  100 kPa  =  100 *10^{3}  Pa

Generally the specific gravity of the second  fluid is mathematically represented as

            S_g_2  =  S_g_1  * \frac{h_1}{ h_2 }  +  \frac{P_a  -  P_A}{\rho_w *  g *  h_2 }

Here  \rho_w is the density of water with value \rho_w  =  1000 \  kg/m^3

=>   S_g_2  =  [14.5 *  \frac{0.22}{0.4} ] +  [\frac{81*10^{3}-100*10^{3}}{ 1000 *  9.8 *  0.4} ]

=> S_g_2  =  3.128

Energy is the ability to do work. True or false
Blababa [14]
Work can be defined as the energy transferred from a body to its sorroundings, the energy spent to move a body, or the energy you need to alter a charged particle, so no energy, no work; thus, the statement is true.

A car interior is heated to 48 C by the sun What type of energy transfer?
Aneli [31]

Answer:

Radiation heat energy transfer

Explanation:

The type of heat transfer from the Sun is radiation heat transfer, which is the transfer of heat through electromagnetic radiation

The distance of the Sun to the Earth is several million kilometers away, with the space between being composes of vacuum and the nuclear reaction in the Sun's core generates vast amount of electromagnetic radiation that is transferred all across the universe and reaches the Earth as visible light and radiant energy at the speed of light

The radiant energy transferred from the Sun heats up the Earth, including the car's interior.

Humpback whales are known to produce a collection of elaborate and repeating sounds with frequencies starting at 20 Hz. The soun
jasenka [17]

Answer:

70 m.

Explanation:

Given,

Frequency, f = 20 HZ

speed of sound, v = 1400 m/s

wavelength of the waves = ?

we know,

v = f λ

\lambda= \dfrac{v}{f}

\lambda= \dfrac{1400}{20}

\lambda=70\ m

Hence, the wavelength of the wave is equal to 70 m.

A scientific law is ____________________A. A rule enacted by the National Academy of Sciences. B. What scientists expect will al
lapo4ka [179]

Your question asks what a scientific law is.

Your answer would be B). What scientists expect will always happen under particular circumstances

A scientific law is something that will always happen, it is mostly like a repeat when doing a experiment with certain factors in place. This is also known as a "natural law" because something will naturally happen when it is enacted with the same factors for multiple "trials". This "scientific law" will allow scientist to predict what would happen during other multiple trials that are conducted. Concise data would be received from these trials.

An example of a scientific law is Newton's law of gravitation.

Therefore, your answer would be B.
