Answer:
column 1: they are solids that form crystals.
column 2: Are liquid solutions.
Explanation:
Crystals are solids, some of them can have viscosity like glass.
Liquid solutions, are formed by some ions dissolved in water, so they can have a definite volume and could be a liquid that is nonviscous because they are dissolved in water.

Explanation:
A. Radio waves have a higher frequency than microwaves.
B. Radio waves have shorter wavelengths than microwaves.
C. Radio waves have lower radiant energy than microwaves.
D. Only radio waves are used in communication.
Answer:The correct answer is option C.
Explanation:
Radio waves and microwaves both are the examples of electromagnetic waves.
Radio waves: These are waves with lowest frequency in the electromagnetic spectrum with longest wavelength.
Microwaves : These are the second lowest frequency waves in the electromagnetic spectrum with wavelength shorter than radio waves.
E = Energy of an electromagnetic wave
= Frequency of the electromagnetic wave
= Wavelength of the electromagnetic wave
Radio waves with longest wavelength has lower radiant energy than the microwaves.Hence, correct option is C.
Answer:
F = 800 N
Explanation:
Given data:
Mass = 80 Kg
Acceleration = 10 m/s²
Force = ?
Solution:
Formula:
F = m × a
F = force
m = mass
a = acceleration
Now we will put the values in formula:
F = m × a
F = 80 kg × 10 m/s²
F = 800 kg.m/s²
kg.m/s² = N
F = 800 N
Answer:
Thomson had discovered the first subatomic particle, the electron. Six years later Ernest Rutherford and Frederick Soddy, working at McGill University in Montreal, found that radioactivity occurs when atoms of one type transmute into those of another kind
