Answer: Experiment 1 could be used to check the gravitational mass of an object.

Step-by-step explanation: Gravitational mass can be described as the strength which the gravitational force has on an object when it is present in the gravitational force. An object at rest will experience only the gravitational force. Whereas an object that is pulled along a horizontal surface with a spring scale will have other forces acting on it along with the gravitational force.

To check for the gravitational mass, an object should only have a gravitational force acting upon it. Hence, experiment 1 is the correct option.

What is 3x * -x yefowe

-BARSIC- [3]

Answer:

- $3x^{2}$

Step-by-step explanation:

-x= -1x. (The 1 is invisible)

Now lets do the 3*-1= -3

You still have both of the x's.

All you do is add them. 1+1=2

So, your exponent is going to be 2 with x attached

***When you are multiplying and you have the same exponent, add them. Pretend that you see the exponent 1 by the x ( $x^{1}$ ) now since you have 2 ( $x^{1} +x^{1}$ ) which equals ( $x^{2}$ )

Looks Like:

3x* -x

=3x* -(1)x

= $-3x^{2}$

Hope this helped :)

What is equivalent to (3 root 8^1/4 x) ?

vfiekz [6]

Answer:

The given expression is equivalent to 3(2^(3/8))x.

Step-by-step explanation:

The given expression (3 root 8^1/4 x) can be written as:

3√(8^(1/4))x

we know that 2^3 = 8

= 3√(2^(3/4))x

We know that √x = (x)^(1/2)

= 3(2^((3/4)(1/2))x

Powers multiply with each other, 3*1/4*2 = 3/8

= 3(2^(3/8))x

If other factors are held constant, what happens to a confidence interval if the sample variance increases? The range of t score

Firlakuza [10]

Answer:

The standard error increases and the width of the interval increases

Step-by-step explanation:

The variance is equal to the square of the standard deviation. An increase in variance will increase the standard deviation.

The width of the confidence interval can be defined as:

$W=UL-LL=2z\sigma/\sqrt{n}$

The width is proportional to the standard deviation, so when the variance increases, the standard deviation and also the width of the interval increases.
