I believe that the answer to the question provided above is that with increase in resistance provided with constant current, Power dissipated will be lessen since power loss is high. Low power dissipation has low heat production.
Hope my answer would be a great help for you.    If you have more questions feel free to ask here at Brainly.

A symbol on a compass or map that is circular with graded points for the direction is commonly known as a _________. question 13
son4ous [18]

Answer;

-Compass Rose

A symbol on a compass or map that is circular with graded points for the direction is commonly known as a compass rose.

Explanation;

The Earth is a magnet that can interact with other magnets such that, the north end of a compass magnet is drawn to align with the Earth's magnetic field.

A compass rose is a figure on a compass, map, nautical chart, or monument used to display the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is a feature on a map that also tells people what direction to go to find certain places on the map

A horizontal air diffuser operates with inlet velocity and specific enthalpy of 250 m/s and 270.11 kj/kg, repectively, and exit
Ivahew [28]

Answer: c) 90 m/s

Explanation:

Given

Invest velocity, v1 = 250 m/s

Inlet specific enthalpy, h1 = 270.11 kJ/kg = 270110 J/kg

Outlet specific enthalpy, h2 = 297.31 kJ/kg = 297310 J/kg

Outlet velocity, v2 = ?

0 = Q(cv) - W(cv) + m[(h1 - h2) + 1/2(v1² - v2²) + g(z1 - z2)]

0 = Q(cv) + m[(h1 - h2) + 1/2(v1² - v2²)]

0 = [(h1 - h2) + 1/2(v1² - v2²)]

Substituting the values of the above, we get

0 = [(270110 - 297310) + 1/2 ( 250² - v²)

0 = [-27200 + 1/2 (62500 - v²)]

27200 = 1/2 (62500 - v²)

54400 = 62500 - v²

v² = 62500 - 54400

v² = 8100

v = √8100

v = 90 m/s

The human ear can detect a remarkable range of sound intensities. The quietest sound that we can hear has an intensity of 10−1
SIZIF [17.4K]

Answer:

I = Io 10^{β/10}

Explanation:

To find a formula for the intensity of sound waves you use the fact that there is a great range of intensity that human can perceive.

The use of logarithms are useful for this kind of systems. For example, if you want a 10 scale for the measurement of the sound level  you can write:

\beta=10log(\frac{I}{I_o})    (1)

I: intensity of sound

Io: hearing threshold

From the equation (1) you can find I in terms of Io and β. You use properties of the logarithms to obtain:

\beta=log(\frac{I}{I_o})^{10}\\\\10^{\beta}=10^{log(\frac{I}{I_o})^{10}}\\\\10^{\beta}=(\frac{I}{I_o})^{10}\\\\I=(I_o^{10}10^{\beta})^{\frac{1}{10}}=I_o10^{\frac{\beta}{10}}

What happens to steam during condensation
Marta_Voda [28]

Explanation:

Condensation is the process of changing the physical state of matter, from gas to liquid state. During condensation of matter, the physical state of the matter changes. Now in this question it is asked that what happens to the steam during the process of condensation. So steam is the matter, and during this process, steam converts its molecules from gaseous to the liquid state without heating. After this process, the steam is converted back to its liquid state. The liquid now take less space than that of the gas and exert less pressure on the walls of the container.
