Answer 1

Explanation:

Question:-

The mass of moon is about 0.012 times that of the earth and its diameter is about 0.25 times that of earth. The value of G on the moon will be?

Answer:-

Concept:-

We need the value of G.

G , is also called Universal Gravitational constant.

Application :-

We need to keep in Mind that:-

G does not change wherever you go in the Universe.

G is same everywhere.

So on moon, it will not change. It will be same as on earth.

Value of G:-

$\boxed{\bf{6.67 \times {10}^{ - 11} N \ m^2 \ per \ kg^2}}$

Henry Cavendish was the first scientist to find out this value.

In this, mass was considered as constant.

Full formula is:-

$\tt{F = \dfrac{G \times m1 \times m2}{r^2}}$

Where F is the force

G is the gravitational constant.

r is the distance.

And, m1 and m2 are masses.

Answer 2

Answer:

the number is 13

Step-by-step explanation:

let the number be x

(x+5)6=108

6x+30=108

6x=108-30

6x=78

x=78/6

x=13
