Which term best describes how fast and in what direction an object is moving at a particular moment? Question 2 options: acceler

ation average velocity position instantaneous velocity
Physics
1 answer:
kompoz [17]2 years ago
7 0

Answer:

Instantaneous velocity

Explanation:

Acceleration = rate of change of velocity

Average velocity = total displacement divided by total time taken

Position = It shows the location of the object

Instantaneous velocity = It is the velocity of an object at a particular instant.

The term that describes how fast and in what direction an object is moving at a particular moment is "instantaneous velocity". It is basically equal to the derivative of position wrt time.

A raven flies south for 100 seconds of 10m/s, then flies 0.50km north in 50 seconds. What is the total distance? What is the tot
Anvisha [2.4K]

Explanation:

given that the raven flies south for

time= 10 sec

speed= 10km/s

we know that speed=distance/time

distance=speed*time

distance=10*100

distance=1000m

distance=1km

also flies

distance=0.5km = 500m

time= 50 sec

speed= distance/time

speed=500/50

speed= 10m/s

speed= 0.01km/s

The average speed of an object is defined as the distance traveled divided by the time elapsed.

average speed= (1000+500)/10+50

average speed= (1500)/60

average speed= 25m/s

average velocity= (10km/s+0.01km/s)/2= 10.01/2= 5.005km/s

How do we find work from a force-displacement graph when the force exerted<br> is not constant?
Artemon [7]

Answer:

Explanation:

Read forces directly from the graph.

Read displacements directly from the graph.

Use the area under the graph to find the work done by the force. This is equal to the kinetic or potential energy the object gains due to the application of the force.

you read in an astronomy book that our milky way galaxy consists of about 200 billion stars. how do you suppose this number was
lapo4ka [179]

By utilizing a galaxy model that accurately explains all of the data that has been collected thus far.

<h3>Suppose it turns out that one in 1 million stars has a planet that at some point in its history is home to an advanced civilization. Then the total number of civilizations that have arisen in our galaxy would be closest to _____. Assume there are about 100 billion stars in the Milky Way galaxy.</h3>

It has been estimated that our galaxy has something close to 100,000 different civilizations.A galaxy is a collection of stars (or solar systems), gas, and dust that is located in a certain area of the universe.

It has been suggested that the Milky Way, the galaxy in which we reside, is replete with extinct civilizations.In conclusion, there are probably close to 100,000 civilizations in our galaxy as a whole.
