Which of these statements is correct about wood and common salt?
morpeh [17]

Answer: Option (C) is the correct answer.

Explanation:

Minerals are inorganic substances which have certain characteristic shape or structure along with homogeneous chemical composition.

It is not necessary that a mineral should be formed under the ground.

Substances which have carbon atoms in their structure are called organic compounds.  The structure of wood has carbon atoms attached thus, wood is an organic compound.

Therefore, we can conclude that common salt is a mineral because it has a definite crystal structure but wood is not a mineral because it is organic.

Explain what effect greenhouse gasses have on climate. How do they have this effect?
Paraphin [41]

Answer:

Greenhouse gases have far-ranging environmental and health effects. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.

A series RL circuit includes a 6.05 V 6.05 V battery, a resistance of R = 0.655 Ω , R=0.655 Ω, and an inductance of L = 2.55 H.
Ivenika [448]

Answer:

The induced emf 1.43 s after the circuit is closed is 4.19 V

Explanation:

The current equation in LR circuit is :

I=\frac{V}{R} (1-e^{\frac{-Rt}{L} })    .....(1)

Here I is current, V is source voltage, R is resistance, L is inductance and t is time.

The induced emf is determine by the equation :

V_{e}=L\frac{dI}{dt}

Differentiating equation (1) with respect to time and put in above equation.

V_{e}= L\times\frac{V}{R}\times\frac{R}{L}e^{\frac{-Rt}{L} }

V_{e}=Ve^{\frac{-Rt}{L} }

Substitute 6.05 volts for V, 0.655 Ω for R, 2.55 H for L and 1.43 s for t in the above equation.

V_{e}=6.05e^{\frac{-0.655\times1.43}{2.55} }

V_{e}=4.19\ V

In a power plant, pipes transporting superheated vapor are very common. Superheated vapor flows at a rate of 0.3 kg/s inside a p
grigory [225]

Answer:h=160.84 W/m^2-K

Explanation:

Given

mass flow rate=0.3 kg/s

diameter of pipe=5 cm

length of pipe=10 m

Inside temperature=22

Pipe surface =100

Temperature drop=30

specific heat of vapor(c)=2190 J/kg.k

heat supplied Q=mc\Delta T=0.3\times 2190\times (30)

Heat due to convection =hA(100-30)

A=\pi d\cdot L

A=\pi 0.05\times 10=1.571 m^2

Q_{convection}=h\times 1.571\times (100-22)=122.538 h

Q=Q_{convection}

19,710=122.538 h

h=160.84 W/m^2-K
