Identify the part of a carrot plant that contains chlorophyll and the part that contains
Alex Ar [27]

Answer:

Leaves and Roots

Explanation:

The leaves of carrots contain chlorophyll which gives them their green color.

Stored in the carrot roots is extra glucose that serves as a food source for the second year's growth of the carrot plant. The carrot plant needs this stored eneergy to reproduce in its second year.

A power plant generates 150 MW of electrical power. It uses a supply of 1000 MW from a geothermal source and rejects energy to t
marissa [1.9K]

Answer:

- the power to the air is 850 MW

- mass flow rate of the air is 84577.11 kg/s

Explanation:

Given the data in the question;

Net power generated; W_{net = 150 MW

Heat input; Q_k = 1000 MW

Power to air = ?

For closed cycles

Power to air Q₀ = Heat input; Q_k - Net power generated; W_{net

we substitute

Power to air Q₀  = 1000 - 150

Q₀ = 850 MW

Therefore,  the power to the air is 850 MW

given that ΔT = 10 °C

mass flow rate of air required will be;

⇒ Q₀ / CpΔT

we know that specific heat of air at p=c ; Cp = 1.005 kJ/kg.K

we substitute

⇒ ( 850 × 10³ ) / [ 1.005 × 10 ]

⇒ ( 850 × 10³ ) / 10.05

⇒ 84577.11 kg/s

Therefore, mass flow rate of the air is 84577.11 kg/s

A steel rod is pulled in tension along its center axis (the axial direction) with a stress that is less than the yield strength.
Kamila [148]

Answer:

D. Axial stress divided by axial strain

Explanation:

 Lets take rod is pulled by force P

Stress σ = P/A

We know that

σ = ε E

E=  Lets take rod is pulled by force P

Stress σ = P/A

We know that

σ = ε E

σ=Axial stress

ε  =Axial Strain = ΔL/L

E= σ/ε

E= Axial stress/Axial Strain

So the modulus of elasticity  is the ratio of axial stress to axial strain.

σ=Axial stress

ε  =Axial Strain = ΔL/L

E= σ/ε

E= Axial stress/Axial Strain

So the modulus of elasticity  is the ratio of axial stress to axial strain.

The option D is correct.
