Newton's law of universal gravitation gives the gravitational force between two objects:
F = GMm/r²
F = gravitational force, G = gravitational constant, M & m are the masses of the two objects, r = distance between the objects
Answer:
D) intermolecular attraction deceased
Explanation:
In order from highest to lowest energies the parts of electromagnetic spectrum are named as
Gamma rays,
X-rays,
ultraviolet radiation,
visible light,
infrared radiation,
and radio waves.
Microwaves are a subsections of radio waves. They are used in microwave ovens to heat the food items.
This is expected EM spectrum in field of science.
Answer:
Base quantities are the minimum numbers of the physical quantities. Base quantities are defined as the physical quantities which can not be defined in terms of other physical quanities. There are seven base quantities. Physical Quantitie Units Derived Quantities are defined as those physical quantities which are derived from the base quantities.
Explanation:
A physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed as the combination of a numerical value and a unit. For example, the physical quantity mass can be quantified as n kg, where n is the numerical value and kg is the unit. A physical quantity possesses at least two characteristics in common, one is numerical magnitude and other is the unit in which it is measured.
Distinguish between a basic physical quantity and a derived physical quantity giving an example of each. Answers. Basic physical quantities are quantities which can be obtained without derivation. e.g Temperature. While derived physical quantities are quantities which can only be obtained from other physical quantities.
Answer:
From Newton's 2nd Law, we have 
. Substituting given values, we have:
