Answer:

The transfer of energy is perpendicular to wave motion.

Explanation:

There is two type of waves in which the classification is done by medium motion of particles.

1) Transverse waves : Here the medium molecules will move perpendicular to the wave propagation. So we can say that here energy is transferred perpendicular to the propagation of wave.

2) Longitudinal waves : Here medium molecules will move parallel to the wave propagation. So here we can say that medium molecules will oscillate parallel to the wave propagation.

So here when girl jump on the stretched string then in that case the wave propagated in the string will be transverse wave and hence the correct answer will be

The transfer of energy is perpendicular to wave motion.

The average distance of Enceladus from Saturn is 238,000 km; the average distance of Titan from Saturn is 1,222,000 km. How much

aleksklad [387]

Answer:

Titan takes 11.634 times longer to orbit Saturn as compared to Enceladus.

Explanation:

We have been given that the average distance of Enceladus from Saturn is 238,000 km; the average distance of Titan from Saturn is 1,222,000 km.

We will use Kepler's Law to solve our given problem.

$\frac{(T_1)^2}{(T_2)^2}=\frac{(r_1)^3}{(r_2)^3}$

Upon substituting our given values, we will get:

$\frac{(T_1)^2}{(T_2)^2}=\frac{(238,000)^3}{(1,222,000)^3}$

$\frac{(T_1)^2}{(T_2)^2}=\frac{13481272000000000}{1824793048000000000}$

$\frac{(T_1)^2}{(T_2)^2}=\frac{13481272}{1824793048}$

$\frac{(T_1)^2}{(T_2)^2}=0.0073878361246365$

Taking square root of both sides, we will get:

$\frac{T_1}{T_2}=\sqrt{0.0073878361246365}$

$\frac{T_1}{T_2}=0.0859525225030452495$

$\frac{T_2}{T_1}=\frac{1}{0.0859525225030452495}$

$\frac{T_2}{T_1}=11.634329870476699\approx 11.634$

$T_2=11.634\cdot T_1$

This implies that time period of Titan about Sturn is 11.634 times more compared to time period of Enceladus about Saturn.

So, basically Titan takes 11.634 times longer to orbit Saturn as compared to Enceladus.

Models are particularly useful in relativity and quantum mechanics, where conditions are outside those normally encountered by h

mylen [45]

Answer:

A model is defined as a structure used to represent an object, usually of a different scale.

Explanation:

In quantum mechanics and particle physics, many of the particles are subatomic, meaning that they are smaller than atoms. This is where a model would be useful. A model could help people to visualise what the particle looks like, and in general would make it easier to understand the behaviour of such a particle.

In The United States how much more sugar is the average person consume each year that in 1970?

zmey [24]

In the 1970, the average American ate only 2 pounds of sugar a year. In 1970, we ate 123 pounds of sugar per year. Today, the average American consumes almost 152 pounds of sugar in one year. This is equal to 3 pounds (or 6 cups) of sugar consumed in one week!

Does the epiglottis close the trachea when u swallow food

stiks02 [169]

Answer:

A flap of tissue called (the epiglottis) sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow. But in some cases, food or drink can enter the trachea. It may go down as you swallow.

Write the physics equation for this graph in slope-intercept form (y=mx+b), expressed in terms of the appropriate variables.

alexgriva [62]

The equation that describes the graph is y = 16.7x + 150.

<h3>What is the equation?</h3>

We have been given the graph of a certain function data set in physics. We know that the graph is the representation of data on cartesian coordinates. In this case, we are asked to find the equation of the graph in the form; y=mx+b

m = slope of the graph

b = intercept of the graph.

To obtain the slope;

m = y2 - y1/ x2 - x1

m = 400 - 200/ 16 - 4

m = 200/ 12

m = 16.7

Then we can see from the graph that the y - intercept is 150. Having these data, the equation that could describe the graph is now;

y = 16.7x + 150
