Answer:
When a number is written in scientific notation (representing the number using powers of base ten) it is expressed so that it contains a digit in the place of the units and all other digits after the decimal point, multiplied by the respective exponent. For example, the number .
On the other hand, it is known the units in the SI for mass, length, time and temperature are kilogram (kg), meter (m), second (s) and Kelvin (K), respectively. In addition, thera are prefixes of the International System (SI) that indicate a specific factor of 10.
For example:
-Giga (G) is a prefix that indicates a factor of
-Pico (p) is a prefix that indicates a factor of
-Mili (m) is a prefix that indicates a factor of
-Micro () is a prefix that indicates a factor of
-Tera (T) is a prefix that indicates a factor of
-Kilo (K) is a prefix that indicates a factor of
Knowing this, let's express these quantities in terms of the SI base units:
Answer:
F = 1.07 x 10⁻⁷ N
Explanation:
The gravitational force of attraction between two objects can be found by the use of Newton's Gravitational Law:
where,
F = Gravitational Force of attraction = ?
G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²
m₁ = m₂ = mass of spheres = 20 kg
r = distance between the objects = 50 cm = 0.5 m
Therefore,
<u>F = 1.07 x 10⁻⁷ N</u>
