Answer: Subtractive colors absorb OR subtract some lights causing it to reflect, and creating white.
Explanation:
Subtractive colors are created by completely or partially absorbing (or subtracting) some light wavelengths and reflecting others.
Answer: Energy requirement or consumption also increases as frequency goes higher. Hence, those low-frequency to mid-frequency waves are commonly referred to as radio waves and essentially, they have longer wavelengths. On the other hand, microwaves have higher frequencies and shorter wavelengths.
Explanation: therefore that's why they don't travel faster.
The density of the substance is<u> 10.5 g/cm³.</u>
The jewelry is made out of <u>Silver.</u>
Density ρ is defined as the ratio of mass <em>m</em> of the substance to its volume V<em>. </em> The cylinder contains a volume <em>V₁ of water</em> and when the jewelry is immersed in it, the total volume of water and the jewelry is found to be V₂.
The volume <em>V</em> of the jewelry is given by,
Substitute 48.6 ml for <em>V₁ </em>and 61.2 ml for V₂.
calculate the density ρ of the jewelry using the expression,
Substitute 132.6 g for <em>m</em> and 12.6 ml for <em>V</em>.
Since 
,
The density of the jewelry is <u> 10.5 g/cm³.</u>
From standard tables, it can be seen that the substance used to make the jewelry is <u>silver</u><em><u>, </u></em>which has a density 10.5 g/cm³.
This is unclear. What are the objects? Is it a balloon? A rubber ball?
The first object also has half the inertia.
Answer: Option A
<u>Explanation:</u>
Inertia is the tendency of an object to remain in its state. It resists the change in the state of object due to any external forces. So the inertia is the property of an object to resists the change in its state due to any kind of external force. Thus as the mass decreases, the central mass of inertia of the object will also decrease as both are directly proportional to each other.
