Sound and light travel at the same speed.

Answer: The object ends up 4.0m north from the starting point, and the magnitude of the displacement is 4.0 m (northwards). ✅

Explanation:

The distance an object travels is the total distance it has moved in all directions. This can be found by adding up the distance it has moved in each direction.

In this case, the object moved 15.0 m north and then 11.0 m south. To find the total distance traveled, we add 15.0 m + 11.0 m = 26.0 m. So the distance traveled is 26.0 meters.

The magnitude of the displacement of an object is the distance and direction between the initial and final position. In this case, the object moved 15.0 m north and then 11.0 m south. So, the object ends up 4.0m north from the starting point, and the magnitude of the displacement is 4.0 m (northwards).

It means that the coordinates of the point were translated using the formula (x, y) since the point rotated at an angle of 180°. (-x, -y). As a result, the necessary rule that characterises the rotation about the origin is as follows: (-x, -y). Example of a 180 degree rotation when rotating a figure about its origin.

The circular movement of an object about a primary axis is referred to as rotation or spin. A revolving object in two dimensions only has one conceivable central axis and can revolve either clockwise or anticlockwise. There are countless conceivable central axes and rotating orientations for a three-dimensional object.

Here are the guidelines for rotation: rotation in the direction of 90°: (x,y) becomes (y,-x) rotation of (x,y) at 90 degrees anticlockwise results in (-y,x) Rotating (x, y) 180 degrees both clockwise and anticlockwise results in (-x,-y)

Thus, the necessary rule that characterises the rotation about the origin is as follows: (-x, -y).

The momentum of the object when expressed using the equivalent units is determined to be 720 g-cm/s.

What are Equivalent Units?

In the given question, momentum, [tex]p=7.2 \times 10^{-3}[/tex] kg-m/s

Here, the momentum is expressed in SI units.

Now, we can convert the units of momentum into CGS system using the following equivalent units.

1 kg = 1000 g and 1 m = 100 cm

So, we get the momentum as,

[tex]p=7.2 \times 10^{-3} \times 1000 \times 100[/tex] g-cm/s

[tex]\implies 7.2 \times 10^{2}[/tex] g-cm/s

[tex]\implies p=720[/tex] g-cm/s

Hence, the  momentum of the object when expressed using the equivalent units is 720 g-cm/s.

Answer:

Explanation:

Given assets are scooter worth $2000, $800 in her checking account.

So total assets = 2000+800 = $2800

And liabilities are which are owed that is $920 and $125.

So total liabilities = 920+125 = $1045

Net worthy = 2800-1045 = $1755

A liability is an obligation owned by a person or company that must be paid based on a certain period, usually based on the value of money. But besides money, liabilities can be in the form of obligations in the form of services, goods, or other economic benefits. In recording the balance sheet, liabilities will be recorded on the right or opposite to assets.

In the accounting equation then abbreviated as ALE which consists of assets, liabilities and equity.

The formula, assets = debt + capital.

Some examples of liabilities are debts, loans, mortgages, deferred income, bonds, guarantees, and other accrued expenses.

If you switch the locations of the parent genotypes around the Punnett square, it would not affect the potential genotypes of their offspring.

A Punnett square may be characterized as a type of table that allows you to determine the expected percentages of different genotypes in the offspring of two parents. It allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes.

The potential genotypes of their offspring would not be affected when you switch the locations of the parent genotypes around the Punnett square. This is because the genotypes of the offspring are formed by the random and systematic segregation of their alleles with respect to their genes.

Therefore, if you switch the locations of the parent genotypes around the Punnett square, it would not affect the potential genotypes of their offspring.

The point estimate and the margin of error for this interval are 0.0265 and 0.1035 respectively.

What is Confidence Interval?

Here, the confidence interval for a difference in proportions is −0.077 to 0.13

We know that, the Lower Bound = Point Estimate - Margin of Error

Also, here, the Lower Bound = -0.077

And, Upper Bound = Point Estimate + Margin of Error

Here, the Upper Bound = 0.13

The Point Estimate can be determined as,

Point Estimate = (Upper Bound + Lower Bound) / 2

[tex]\implies[/tex] Point Estimate [tex]=\frac{0.13+(-0.077)}{2}[/tex]

[tex]\implies[/tex] Point Estimate [tex]=0.0265[/tex]
