Explanation

The zeroth law of thermodynamics states that if two thermodynamic system are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other.

Explanation

A free-falling object has an acceleration of 9.8 m/s/s, downward 

Explanation

2 + 1 = 3

3 + 2 = 5

5 + 3 = 8

8 + 4 = 12

12 + 5 = 17

17 + 6 = 23

Explanation

There are n cows: 
First son gets: 2n​

Second son gets: 4n​

Third son gets: 5n​

Fourth son gets: 7 cows

Therefore, sum of cows each son gets equals the total number of cows
2n​+4n​+5n​+7=n
7=20n​
n=140

Explanation

x + 5x + 10x = 640

16x = 640

x = 40

∴ no. of notes = 40×3=120

Explanation

Let A be the amount of type of first rice and

B be the Amount of second type of rice

According to question:  A + B = 50 Kg

Also

                           A  x 4.5 + B x 5 = 240 Rs

Thus solving the above two equations

                    (50 – B) x 4.5 + 5B = 240

                       225 – 4.5 B + 5B = 240

                                          0.5 B = 15

                                                 B = 15/ 0.5

                                                 B = 30 Kg

                                        Thus A = 50 – 30 = 20 Kg
