Answer:

The speed of light is c = 299,792,458 m/s. a. Write this value in scientific notation. b. Express the speed of light to i. five significant figures, ii.three signaficant figures

Answer:

(a)2.99792 458 ×[tex]10^8[/tex] m/s is the speed of light in scientific  notation,

B) - (i) The speed of light to  five significant figures is 2.9979 ×[tex]10^8[/tex]m/s ,

(ii)The speed of light to three significant figures  is 3.0 × [tex]10^8[/tex] m/s .

Explanation:

Given , speed of light = 299,792,458 m/s

• Scientific  notation- Very big or very small numbers can be written using scientific notation. When a number between 1 and 10 is multiplied by a power of 10, the result is written in scientific notation
• So , the speed of light  in scientific notation = 2.99792458 ×[tex]10^8[/tex] m/s .

• Now , speed of light to five significant figures ,

Speed of light = 2.9979 ×[tex]10^8[/tex] m/s

• And speed of light to three significant figures is ,

Speed of light = 2.99 × [tex]10^8[/tex] m/s .

This can be written as  3.00 × [tex]10^8[/tex] m/s because 9 is greater than 5 .

Final answer:

Hence , 2.99792 458 ×[tex]10^8[/tex] m/s is the speed of light in scientific  notation,

The speed of light to  five significant figures is 2.9979 ×[tex]10^8[/tex]m/s ,

The speed of light to three significant figures  is 3.0 × [tex]10^3[/tex] .

a=. So when we reverse the formula mass= weight÷ gravity. We can take gravity as g=9.8. So 294÷9.8=30. The mass is 30 kg.

b=. The mass of the object is 294/9.8. The result you get will be multiplied with 1.63, thats the weight in the moon. P. S: Acceleration due to gravity in the moon is one sixth of acceleration due to gravity on eart

Explanation:

Objects weight on earth = 250 N

The objects mass = (250 / 9.81) = 25.49 Kg.

The objects weight on the moon = 25.49 * 1.625 = 41.41 N.

[Note-1: The acceleration due to gravity on the surface of the Moon is about 1.625 m/s2]

[Note-2: weight = mass x gravity]

Step-by-step explanation:

Since the union of A and B represents the set of all elements of A and B, its negation is the empty set. The negation of the set A contains all the elements of B which are not also elements of A. Likewise, the nagation of the set B contains all the elements of the set A which are not elements of the set A at the same time. This implies that the intersection between not-A and not-B is the empty set, since not-A and not-B share no elements at all. Therefore, the given statement is verified: (A U B)' = A' intersection B' = the empty set. In the picture below, the empty set is represented by the absence of colored regions.
