if an objects first movement is 3.0m North and another movement is 4.0m West, what is the magnitude of the displacement made ove
Snezhnost [94]

If an object's first movement is 3.0m North and another movement is 4.0m west, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.

<h3>What is displacement?</h3>

Displacement is a vector quantity. This indicates that it has both a direction and a magnitude and that it is visually represented as an arrow that points from the starting position to the ending position.

As given in the problem if an object's first movement is 3.0m North and another movement is 4.0m west

Resultant displacement can be calculated with the help of the triangle law of the vector addition,

Resultant = √( 3² + 4²)

                =√25

                = 5.0 m

Thus, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.

Chose a substance your familiar with. What are it’s physical and chemical properties
finlep [7]
So, physical properties are what we can detect with our basic 5 senses or measuring tools, and the things that, when changed, dont actually change the chemical properties (like atoms and molecules). Lets take wood for an example: its brown, its solid, it can be big or small, it has a taste and smell, its boiling, freezing or melting point...

Chemical properties, on the other hand, are the things we can change with, for example, experiments and tools. Does it burn? Can it rust/oxidize? How does it react with other chemicals? Is it radioactive, or toxic? All of these are chemical properties you can probably answer.

A tuning fork produced four beats per second with a second, 270-Hz tuning fork. What are the two possible frequencies of the fir
EleoNora [17]

Answer:

frequency of the first tuning fork can be 274 Hz or 266 Hz

Explanation:

Given data :

we have number of beats per second = 4

thus, it can also be written as

Beat frequency of the tuning fork, v = 4 Hz

Frequency of the tuning fork, f = 270 Hz

now, the beat frequency is actually the difference of the consecutive frequency.

thus, we have

Frequency of the first tuning fork as = 270 Hz + 4 Hz = 274 Hz

or

Frequency of the first tuning fork as = 270 Hz - 4 Hz = 266 Hz

Therefore, the frequency of the first tuning fork can be 274 Hz or 266 Hz
