A heat engine operates between a hot reservoir with a temperature of 400 K and a cold reservoir with a temperature of 300 K. The
natali 33 [55]

Answer:

Explanation:

Given

Temperature of Hot reservoir T_1=400 K

Temperature of Cold reservoir T_2=300 K

Heat reservoir Q=500 J

Work done W=150 J

heat Exhaust Q_{rejection }=350 J

Q=W+Q_{rejected}

500=150+350

L.H.S=R.H.S

thus it follows first law

\eta _{carnot}=1-\frac{T_L}{T_H}

\eta _{carnot}=1-\frac{300}{400}

\eta _{carnot}=0.25

Cycle Efficiency

\eta =\frac{W}{Q}=\frac{150}{500}=0.3

Carnot efficiency is less than cycle thus it violates second law

Plants may get yellow if they get less nitrogen.give reasons.​
Vaselesa [24]

Explanation:

Nutrient deficiency causes yellowing of leaves. One of such nutrient is Nitrogen.

  • Leaves are green because of a pigment in them called chlorophyll.
  • The chlorophyll in leaves are used by plant to absorb light energy needed for photosynthesis.
  • Other wavelength of light is absorbed by the chlorophyll and the green color is reflected.
  • Nitrogen is an important nutrient that is needed to produce chlorophyll in plants which in turn helps the process of photosynthesis.

An automobile traveling 50km/hr. It decelerates at 5 meter per second square. How long will it take to stop the car? How far wil
const2013 [10]
We know, a = v/t
Here, a = 5 m/s²
v = 50 km/h= 13.88 m/s

Substitute their values into the expression:
5 = 13.88 / t
t = 13.88/5
t = 2.78 sec

Now, we know, v = d/t
13.88 = d/2.78
d = 13.88 * 2.78
d = 38.53 meter

In short, Your Answers would be:
i) It will take 2.78 sec
ii) It will travel for 38.53 m after a brakes applied.

Hope this helps!
