A spool is on a horizontal surface (with friction) and pulled to the right with a thread attached to the center of the spool, so that the spool rolls without slipping. the spool has a mass of m, moment of inertia i, and a radius of r

Answers

Answer 1

The relationship between the magnitude of the force of tension and the force of friction is; Ff = (r/R)Ft

What is Rotational Acceleration?

We are given;

mass of spool = M

Radius = R

moment of inertia = I.

Now, the spool is not moving and as such;

r < R which means there is net torque = 0

Thus;

Ff × R = Ft × r

>> Ff = (r/R)Ft

Finally, the angular acceleration is expressed as;

α = a/R

A student ran a distance of miles each day for 5 days. then the student ran a distance of miles each day for the next 5 days. what was the total distance in miles the student ran during these 10 days?

Answers

Hence, The total distance in miles the student ran during these 10 days is 38.75 miles.

What is distance?

Distance is the total length between two points.

To calculate the total distance in miles covered by the student, during these 10 days ran, we use the formula below

Formula:

D = d₁T+d₂T........... Equation 1

Where:

D = Total distanced₁ = distance covered each day in the first 5 daysd₂ = distance covered each day in the next 5 days

From the question,

Given:

d₁ = 3[tex]\frac{1}{2}[/tex]miles = 7/2 milesT = 5 Daysd₂ = 4[tex]\frac{1}{4}[/tex] miles = 17/4 miles

Substitute these values into equation 1

D = [(7/2)×5]+[(17/4)×5]D = 17.5+21.25D = 38.75 miles

Hence, The total distance in miles the student ran during these 10 days is 38.75 miles.

Target profit is $100,000; total fixed costs are $120,000, and total variable costs are $500,000, the markup percentage is

Answers

The markup percentage to the variable cost using the variable cost method is 40%.

What is markup percentage?

The markup percentage to the variable cost using the variable cost method can be obtained by dividing the addition of the target profit and total fixed cost by the total variable cost as follows.

We know that:

Total fixed cost

= Fixed overhead costs + Fixed selling and administrative costs

= $120,000 + $50,00

= $170,000

The markup percentage to the variable cost

= (Target profit + Total fixed cost) / Total variable cost

= ($100,000 + $170,000) / $675,000

= $270,000 / $675,000

= 0.40, or 40%.

Use a direct proof to show that the sum of two odd integers is even

Answers

Below is the proof that the sum of two odd numbers is always even.

How to prove that the sum of two odd numbers is even?

First, remember that an even number is written as:

x = 2*n

Where n is an integer number.

While an odd number will be written as:

y = 2*n + 1

Now, let's say that we have two odd numbers:

A = 2k + 1

B = 2n + 1

If we add these we get:

A + B = (2k + 1) + (2n + 1) = 2k + 2n + 2 = 2*(k + n + 1)

And k + n + 1 is an integer number, then we can write:

k + n + 1 = N

So we get:

A + B = 2N

Then the sum of A and B is an even number.

Thus, we proved that for the sum of any two odd numbers, the outcome will always be even.

(WILL MARK BRAINLIEST!) If a student attends a non-credited high school, or in their case a homeschooling program, will they have to take the SAT/ACTs to be able to attend community college? Please answer explaining how a student such as this can get into college and the requirements they would need.

Answers

Answer:

So I turned homeschool not too long ago and you do need to the the SAT/ACT depending on which community college it is? If the high school or college offer ACT then the test you most likely need to take is the ACT. But if the test they offer is SAT then you should take that. Taking both of the SAT and ACT would only do better on your resume/aplication so it's really up to you. I plan to take both if I have the time. But I heard most people take the ACT. You should check what your community usually offer.

Hope this helps.

Explanation:

Answer:  college admissions is handled very similarly for homeschoolers as it is for traditionally schooled students. In fact, many admissions offices actively seek out homeschoolers. Admissions officers evaluate each student within the context of his/her own background and the opportunities they've had. There are, however, a few differences regarding how homeschoolers submit certain application materials. As a homeschooled student, your parent or primary teacher is responsible for creating your high school transcript and for sending it to your colleges. Parents have a few different options for going about this:

 1. Working under an umbrella school that produces official transcripts and diplomas

2. Creating their own transcript and diploma

3. Enlisting a service that specializes in transcript and diploma creation

4. Joining a homeschool group that produces professional transcripts and diplomas

Explanation:

Your transcript should include all of the following information:

Your name, the name of your homeschool (if applicable), address, and phone number

Your high school course list ordered by year (grades 9-12)

The institution where each class was taken (i.e. homeschool, online institution, community college)

The grade scale being used in your homeschool

Your overall GPA

Credits given per course (listed per semester and per year)

Expected graduation date

Parent signature with a date

Homeschoolers do not need a GED or a diploma to apply to college or qualify for financial aid; you just have to declare that your homeschool education meets state law requirements. Most homeschooled students choose not to take the GED if they have valid transcripts, as colleges will place the most emphasis on your transcript and standardized test scores. If you’re homeschooled through an online academy, virtual school, or organized homeschool program then they will award your diploma according to their own standards. If you’re homeschooled independently by your parents, then your parents have the option of issuing you a diploma if your transcripts indicate you’ve met the basic state requirements for graduation. When filling out the FAFSA, be sure to check “homeschooled” when it asks for your high school completion status. Even if your homeschool is administered through an umbrella organization, you should still check “homeschooled” instead of “high school diploma” to avoid any delays in the processing of your application.

For the molecule cyanazine, the hybridization of atom 1 would be a sp³ hybridization when lone pairs are added.

What is hybridization?

Hybridization is a phenomenon in chemistry which involves the linear combination of two (2) or more atomic orbitals of a molecule or chemical compound, in order to form the same number of hybrid orbitals, with each of the orbital having equal amount of energy and the same shape.

Since nitrogen (N) in cyanazine is bonded with three (3) single bonds, two carbon (C) and one hydrogen (H) bond, we can deduce that the hybridization of atom 1 would have a sp³ hybridization.
