Your clothing tends to cling together after going through the dryer. Why? Would you expect more or less clinging if all your clo

lys-0071 [83]

Answer and Explanation:

The clothing after spinning in the dryer cling together. This is because in the dryer they are rubbed against each other and due to this rubbing, electrons are transferred from one to the other clothes and acquire charge as a result of charging by friction thus producing static electricity.

As the material of the clothes in the dryer is different, clinging will be more.

The sticking of these clothes together is known as Static cling.

In case, the clothing are of same material, the static electricity produced as a result of frictional charging would be less and hence less static cling would occur.

Which graph represents a function with direct variation? A coordinate plane with a line passing through (negative 4, 0) and (0,

fgiga [73]

Answer:

Answer:

A line passing through the points (-1,-4),(0,0) and (1,4)

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form y/x=ky/x=k or y=kxy=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Verify each case

Part 1) A line passing through the points (-4,0) and (0,-2)

This line not represent a direct variation, because the line not passes through the origin.

Part 2) A line passing through the points (-5,4) and (0,3)

This line not represent a direct variation, because the line not passes through the origin.

Part 3) A line passing through the points (-4,-6) and (0,3)

This line not represent a direct variation, because the line not passes through the origin.

Part 4) A line passing through the points (-1,-4),(0,0) and (1,4)

The line passes through the origin

Find out the value of k

k=y/xk=y/x

For the point (-1,-4)

substitute

k=-4/-1=4k=−4/−1=4

For the point (1,4)

substitute

k=4/1=4k=4/1=4

The linear equation is y=4xy=4x

This line represent a direct variation

Since there are no aurora observed on Venus we can conclude that Venus a. lacks atmospheric oxygen b. is too hot for magnetic fo

Brrunno [24]

Answer:

Yes, Venus does not have the same magnetic field as that of earth's

Explanation:

Instead, there are solar wind particles that can deeply penetrate the venus atmosphere and can collide with the other carbon atoms already present in the air but lacks oxygen and thus does not have that strong magnetic field which would deflect the suns rays and create aurora in the sky at night.

I have an algerbra 2 question.

Andreyy89

In order to find out if the exponential function represents a growth or a decay, let's look at the number that is base to the exponent x.

If the number is greater than 1, so the function represents a growth, and if the number is less than 1, the function represents a decay.

Since the number is 1.075, the function represents a growth.

To find the % increase, first let's convert the number to percentage, and then subtract 100%:

$\begin{gathered} 1.075=1.075\cdot100\text{\%}=107.5\text{\%} \\ 107.5\text{\%}-100\text{\%}=7.5\text{\%} \end{gathered}$

So the percent increase is 7.5%.
