Answer:

A mineral is a valuable form of ore that can be extracted from the ground

Explanation:

Gold, quartz and talc are minerals because they are found in the earth in a valuable form of ore while ores are rocks that contain valuable concentrations of minerals.that can be mined.

An ORE in general term can be said to be a mineral deposit that contains enough Minerals that can be mined in commercial quantities while Minerals are valuable components of an Ore that can be mined ( naturally occurring ) in an ORE.

4. Explain the doppler effect. Be sure to talk about how the wave changes, the perceived change hear by a person that an emitted

Lemur [1.5K]

Answer:

4) The Doppler effect is the frequency change that occurs in a wave by the relative movement of the emitter and the observer

5) Sound originates from a repetitive movement of air molecules

6) The principle of stable superposition that if the medium complies with the elastic regime, the waves traveling in it can be added

Explanation:

4) The Doppler effect is the frequency change that occurs in a wave by the relative movement of the emitter and the observer. In the specific case of the fixed observer, each wave that is emitted travels at a constant speed, but as the emitter approaches the next wave lLa in less time, so the wave maxima are closer to each other

v = λ’ f’

λ‘=λ -Δλ = λ - vs / f

f’= v / λ’ = v / (λ - vs / f) = v / (v / f - vs / f)

f ‘= f v / (v-vs)

5) Sound originates from a repetitive movement of air molecules, this movement creates a longitudinal wave, which we call sound. It is characterized by the air volume module and its density

6) The principle of stable superposition that if the medium complies with the elastic regime, the waves traveling in it can be added

y total = y₁ + y₂

Let's see as an example two waves of the same amplitude that travel in the same direction, if this wave the maximums coincide they add up obtaining that the maximums are twice the amplitude

If the wave goes in the most directive but the maximum of one coincides with the minimum in the other, the sum gives zero,

The wave travels in the opposite direction, in this case the resulting wave in constant in time and we call it resonance

Relating the circumference to the force applied on the balloon, make a conclusion on the relationship of force to the rate of th

natka813 [3]

At a constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

The force applied to an object can be determined by applying Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

F = ma

where;

<em>m is the mass of the balloon</em>
<em>a is the change in velocity per time</em>

$F = m\frac{\Delta v}{t} \\\\\frac{F}{\frac{\Delta v}{t}} = m$

The mass of an object is inversely proportional to the rate of change motion of the object.

Thus, we can conclude that at constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.
