Name three situations in which force is created. describe the cause of the force in each situation

Answers

Answer 1
Answer: One situation in which force is created is when an object is moving and a force is created to stop that movement. Second situation is when an object is moving circularly and a force is created to move it towards the middle of the circle. The third situation is when a force is created that goes in the same direction as an object that is in movement.

Compare the time taken by the RC car to cover the same distance. Do some go faster or slower?

Answers

There isn;t enough given values to define and determine what is asked. But since
distance = speed / time, time = distance / speed


Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2. In order to calculate the acceleration of the boat we first have to identify the suited formula for acceleration in this scenario. 

Hence, a = vf – vi / t. Vi = 15 m/s Vf = 45 m/s T = 6 seconds   

Solution: 
A = 45 m/s – 15m/s / 6s 
A = 5m/s^2

The shorter the time required to cover the same distance, the greater the speed of the RC car.

Further explanation

Acceleration is rate of change of velocity.

\large {\boxed {a = (v - u)/(t) } }

\large {\boxed {d = (v + u)/(2)~t } }

a = acceleration (m / s²)v = final velocity (m / s)

u = initial velocity (m / s)

t = time taken (s)

d = distance (m)

Let us now tackle the problem!

The formula for finding speed is:

\large {\boxed {v = (s)/(t)} }

v = velocity (m/s)

s = distance (m)

t = time taken (s)

From the formula above, it is clear that speed is inversely proportional to travel time. The shorter the time required to cover the same distance, the greater the speed of the RC car.

For example, let's look at the data in the table in the attachment. RC Car B has the greatest speed

Which type of wave interaction is shown in the diagram?wave A
MAAAAA
wave B
MAAAA
wave A + B
PAMA
A. Destructive interference
B. Diffraction subtraction
C. Diffraction gradient
D. Constructive interference

Answers

Answer: Constructive interference

Explanation: Just took the test

Final answer:

The diagram shows destructive interference between two waves, resulting in a smaller amplitude wave.

Explanation:

The type of wave interaction shown in the diagram is destructive interference.

In destructive interference, two waves combine and create a new wave with a smaller amplitude. This occurs when the crests of one wave align with the troughs of another wave, causing cancellation.

In the diagram, wave A and wave B are out of phase, meaning their crests and troughs do not align. When they combine, the resulting wave has a smaller amplitude than either individual wave, indicating destructive interference.

What is the persistent fear of snow falling

Answers

Chionophobia is the extreme dislike or fear of snow.

The word originates from Greek 'chion' meaning snow and 'phobos'
meaning fear, aversion or dread. People with Chionophobia often
understand that their fear is unfounded and weird. However, they
are unable to control it.

Another contributor was the first to answer the question correctly, and in fact,
I learned the answer from that earlier post.  If I could only remember who it was,
I would give them a big shout-out.  Their answer was deleted by a moderator
because it didn't have an explanation with it. 

explain why the motion of a body which is moving with constant speed in a circular path is said to be accelerated ?

Answers

In this case when a body moves in circular path acceleration is called Centripetal acceleration... Body in circular path moves with constant speed but its direction changes at every instant of time ...as acceleration is produced when either magnitude or direction of velocity changes...here magnitude remains same but direction changes so body is said to be accelerated....
as its velocity changes and hence is known as accelarated

A helicopter flying west begins experiencing an acceleration of 3m/s2 east. Will the magnitude of its velocity increase or decrease?

Answers

The acceleration measures the change in velocity.

Since the acceleration is in the direction opposite to the speed, the velocity eastwards will decrease : its magnitude will first decrease, then it reach 0 m/s, then finally it will increase again.

Which of the following actions or events did not contribute to the Dust Bowl? Farmers in the Central U.S. had plowed grasslands to grow food crops to feed the increasing human population. They left the fields plowed and bare in the winter months when crops were not grown, and this left the soil exposed to wind. A long drought in the 1930s left the exposed soil especially dry due to the lack of precipitation. With the advent of pesticides, minerals in the ground were leached.

Answers

The following cause that is notconsidered in the formation of a Dust Bowl is the lack of farmers in Oklahoma.The answer is letter B. in fact, the number of farmers increases due to thehigh grain prices of Worl War I that encourages farmers to plow millions ofacres of natural grass to plant wheat.
