what is called the phenomenon of prolongation of sound​

Answers

Answer:

It is called reverberation.

Explanation:

The phenomenon of prolongation of sound is the process in which sound produced is reflected from plane surfaces in a continuous manner, which leads to reverberation of sound waves. It can also be referred to as a condition of continuous echo production.

It occurs when sound produced get reflected from a hard plane surface, and in the process hits another surface and another reflection occurs. This continuous reflection leads to prolongation of sound.

The sound produced is heard for some specific period of time before it dies down or get absorbed finally.

Sunlight is a form of electromagnetic energy.

which motion is caused when two opposite force acting perpendicular to an axis.

Answers

Answer:

fiction

Explanation:

When two opposite forces act perpendicular to an axis, it causes rotational motion or torque.

What is the difference between torque and a couple?

Torque and couple are both related to rotational motion and are often used interchangeably, but they refer to slightly different concepts.

Torque is a measure of the force that causes an object to rotate around an axis or pivot point.

It is equal to the force applied multiplied by the perpendicular distance between the axis and the line of action of the force. Torque is a vector quantity, meaning it has both magnitude and direction. Its unit of measurement is Newton-meters (Nm) or foot-pounds (ft-lbs) in the English system.

A couple, on the other hand, is a pair of equal and opposite forces that act on a body but do not cause it to translate. Instead, they create a pure rotational motion.

A couple generates torque, but unlike a single force, it doesn't have a line of action or a specific point of application. Instead, a couple is characterized by its magnitude and the distance between the forces. Couples are often used in mechanics to model rotational systems and analyze the behavior of rotating bodies.

Torque is the measure of the force that causes rotational motion, while a couple is a pair of forces that create pure rotational motion without causing any translation.

Therefore, If two opposite forces act perpendicular to an axis, it causes rotational motion or torque.

A zebra drinks from a watering hole and is ambushed by a crocodile. What's more important and why: the zebra having a high maximum speed or a high acceleration?

Answers

Answer:

before this type of attack, high acceleration is the most important thing.

Explanation:

As the zebra is ambushed by the crocodile the most important thing is a quick reaction, in this attack the most likely is that the crocodile is in the water so it cannot run after the zebra.

Consequently, before this type of attack, high acceleration is the most important thing.

Two children are fighting over a 2 kg toy. One child pulls right with a 5 N force and another pulls left with a 7.5 N force. How long will it take the toy to reach a speed of 1.0 m/s in this “tug of war”?

my answer = 1.25 s

Answers

Answer:

0.8sec

Explanation:

Σf= 7.5-5= 2.5 N to the left

Σf=m*a=>2.5=2a=>a=1.25 m/s²

Lets say that the speed is 1m/s

a=speed-0/x=>x=1/1.25=>x=0.8

Hence the time will be 0.8sec

How would the force of gravity between two objects change if the mass of
each object were doubled?
A. The force between them would be 2 times larger than with the
initial masses.
B. The force between them would be 1/4 the force with the initial
separation.
C. The force between them would be 4 times larger than with the
initial masses.
D. The force between them would be 1/2 the force with the initial
separation

Answers

Answer:

Option C. The force between them would be 4 times larger than with the

initial masses.

Explanation:

To know which option is correct, we shall determine the force of attraction between the two masses when their masses are doubled. This can be obtained as follow:

From:

F = GMₐM₆/ r²

Keeping G/r² constant, we have

F₁ = MₐM₆

Let the initial mass of both objects to be m

F₁ = MₐM₆

F₁ = m × m

F₁ = m²

Next, let the masses of both objects doubles i.e 2m

F₂ = MₐM₆

F₂ = 2m × 2m

F₂ = 4m²

Compare the initial and final force

Initial force (F₁) = m²

Final (F₂) = 4m²

F₂ / F₁ = 4m² / m²

F₂ / F₁ = 4

F₂ = 4F₁ = 4m²

From the above illustrations, we can see that when the mass of both objects doubles, the force between them would be 4 times larger than with the

initial masses.

Thus, option C gives the correct answer to the question.
