Explanation:
Given
First stone is drop from cliff and second stone is thrown with a speed of 52.92 m/s after 2.7 s
Both hit the ground at the same time
Let h be the height of cliff and it reaches after time t
For second stone
---2
Equating 1 &2 we get
The mass of an electron, me, 9.11 × 10⁻³¹ kilograms shows there are 3 important numbers in them, namely numbers 9, 1, and 1
<h3><em>Further explanation</em></h3>Significant numbers are obtained from measurement results of exact numbers and the last number estimated
This is called significant numbers
the scientific notation can be described as:
a, ... x 10ⁿ
a, ... called a significant number
10ⁿ is called a big order
Rules for significant numbers in general:
- 1. All non-zero numbers are significant numbers
- 2. a zero which is located between two non-zero numbers including a significant number
- 3. all zeros are located in the final row written behind the decimal point of the include significant number
- 4. zero decimal point is the not significant number
From the numbers known in the question amounting to 9.11 × 10⁻³¹ kilograms shows there are 3 important numbers in them,(symbol a, before a big order ,called a significant number) namely numbers 9, 1, and 1
