Answer: energy

Explanation: A wave is a disturbance that transfers energy as it travels through medium.

Vikentia [17]3 years ago

Answer:

Option (1)

Explanation:

All waves can carry energy, and this energy can be high or low. The waves that carry high energy are commonly known as the high energy waves such as X-rays and gamma rays. On the other hand, those waves that can carry low energy are considered to be low-energy waves such as radio waves.

There are two types of waves that carry energy, namely the electromagnetic wave and the longitudinal waves.

In the case of electromagnetic waves, the energy is transported in the form of vibrations of both electric as well as magnetic field. Whereas, in the case of longitudinal waves such as sound waves, this energy is carried through a medium in which the sound propagates.

Thus, the correct answer is option (1).

Friction provides the force needed for a car to travel around a flat, circular race track. What is the maximum speed at which a
ad-work [718]

Answer:

Maximum speed of the car is 17.37 m/s.

Explanation:

Given that,

Radius of the circular track, r = 79 m

The coefficient of friction, \mu=0.39

To find,

The maximum speed of car.

Solution,

Let v is the maximum speed of the car at which it can safely travel. It can be calculated by balancing the centripetal force and the gravitational force acting on it as :

v=\sqrt{\mu rg}

v=\sqrt{0.39\times 79\times 9.8}

v = 17.37 m/s

So, the maximum speed of the car is 17.37 m/s.

Does research lessen its value for its being cyclical? Enumerate Two Possible advantages of a cyclical research
Tanya [424]

Answer:

Research usually is a cyclical process because it starts with a problem and ends with a problem.

This is bad or lessens the value of the research?

No, because there are problems that in nature are cyclical, (for example the related ones to action research).

And it also may be a good thing, solving one "problem" leads to another problem, but in the process of solving the first one we may win a lot of knowledge, and the same happens with the next one, and so on.

Two possible advantages of cyclical research are:

Knowing beforehand that the research will be cyclical, will allow us to estimate better the amount of time and money needed because we already know (more or less) where to aim.

It also may lead to a better end product, as we already know that we must focus in solving one thing and then we can focus in the next one.

Another possible advantage may be that we know that after the work, there will be a new thing to research, and it is fun, so if you are curious enough this may be a good thing (especially in scientific areas, physics, chemistry, etc).

How is it possible to get three precise but inaccurate measurements of the same volume of water
Lubov Fominskaja [6]
The inaccurate measurements must be similar to the other two measurements (ex; 590, 589, 599), but different from the actual volume of water. (Ex; the actual volume is let say.. 100, but you measured 50, 49, 40)

Which best describes a major characteristic of both volcanoes and earthquakes? they are centered at the poles?
Arturiano [62]
<span>A major characteristic of both volcanoes and earthquakes is that they are located in the same geographic area. Most earthquakes are along the edges of tectonic plates. This is where most volcanoes are too. Most earthquakes directly beneath a volcano are caused by the movement of magma.</span>
