Explanation:
Given parameters
Period = 2.34minutes
Unknown:
Frequency of the oscillator = ?
Solution:
Frequency is the number of waves that passes through a point at a given time. It is the inverse of period which is the time it takes for a wave to pass through a medium:
F = 
F is the frequency
T is the period
To solve this, convert the period to seconds:
2.34minutes to seconds:
1 min = 60seconds
2.34 = 60 x 2.34 = 140.4s
F = 
= 0.007hz or 0.007s⁻¹

No, an element is a pure substance, it cannot be broken down into simpler substances or be decomposed by chemical means.
Answer;
= g/cm^3
Explanation;
-Density is the mass per volume of a substance, or the weight per volume of an object. The Metric System is a type of system of measuring that uses only one root word for each basic dimension, such as, -gram for mass or -meter for distance.
-Metric system densities are usually in the units of mass per volume, such as g/cm^3 (gram per cubic centimeter). Where grams represents the units of mass and cm^3 represents the volume.
The answer is 297.14 g/mol
Answer:
Molecules
Explanation:
Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space.
