The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temp
natali 33 [55]

Answer:

Relative humidity %

Explanation:

  • The relative humidity is the percentage of the water vapor content at a particular temperature and pressure to the maximum amount of water vapor content the air can hold at those conditions.
  • When the relative humidity of the air becomes 100% then there occurs precipitation on the earth from the atmosphere (specifically troposphere, which accounts for the weather changes).
  • We might have experienced excessive sweating even on a relatively less hotter day of a summer which is on account of increased relative humidity.

If chilled coke and hot tea are kept together tea cools down but coke gets warm .why?​
Harlamova29_29 [7]

When hot tea is mixed to chilled coke, tea loses heat and coke gains heat. Thus, tea cools down but coke gets heated. Because it is liquid and liquid does not totally cool down to the ambient temperature, it and the iced drink will eventually reach the same temperature.

How do u work out weight c and d and what r the answers
Ket [755]
The whole secret of things that are balanced on a pivot like this is:

The sum of all of the 'moments' is equal on both sides.

The moment of each weight is  (the weight) times (its distance from the pivot). 
If you add up those for each eight on one side, it has to be equal to the sum
of all the ones on the other side.

<u>2. a).</u> 
The moments on the right side are:  (4 x 0.15) and (1 x 0.40).
They add up to  (0.60 + 0.40) = 1.00

The only moment on the left side is  (C x 0.25).  Both sides have to be equal.

C x 0.25 = 1.00

Divide each side by 0.25, and you have    C = 4 N .

===========================================

<u>2. b).</u>
The only moment on the left side is  (5 x 0.40) = 2.00

The moments on the right side are (1 x 0.20) and (D x 0.30)
They add up to  (0.3D + 0.2).

Both sides have to be equal.    0.3D + 0.2 = 2.0

Subtract 0.2 from each side:      0.3D  =  1.8

Divide each side by 0.3:                D = 6 N
