A 1-hectare field contains 2500 bean plants having a total leaf surface area of 557 m2. ambient temperature is 21°c, winds are calm, and humidity is 45%. if each plant is transpiring at the average rate determined for treatment a in 6 above, how much water is lost from the field each hour due to transpiration? show your calculation in the space below.

The field losses a total of 55.814 litres of water in an hour.

Explanation:

As the complete question is not given here, the average rate of water loss is not given here which is found in normal conditions as 1.67 mL/m2.

Now the average rate of water loss per minute is 1.67 mL/m2

So the average rate of water loss per minute for 557 m2 is 1.67*557=930.19 mL

So 930.19 mL of water is lost from the field in 1 minute, for the calculation of water lost in an hour, the value is given as  60*930.19 =55811.4 mL or 55.814 litres.

i believe it is b. what was the cause of the big bang

hope this !

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
