Not part of bicycle

Machines

April 7, 2019

Question

which simple machine is not a part of the bicycle: pulley, lever, screw, or wedge?

fiaz - Guyana (28992)

Answer

You push on the pedals, which is a lever. The bicycle chain forms a pulley. Bicycles have screws to to hold things together. However, I can't think of where a wedge would be used, so a wedge probably is not part of a bicycle.

Would you be able to assist us in helping individuals and their loved ones seeking support by sharing our new mental health resource https://www.therecoveryvillage.com/mental-health/ on your site? It includes valuable information on mental health support, co-occurring disorders, and treatment options as well as phone numbers for The Recovery Village, alcohol abuse, drug abuse, and other national hotlines.

With your assistance, we'll be able to raise mental health awareness and provide support to those in need.

Fall prevention handbook

Aging

February 26, 2019

Question

Hi,

Every 11 seconds, another senior has been treated in the emergency room for a fall-related injury. That statistic recently hit home for me personally when my dad fell last summer. So, I and a few others at Senior Caregiver Alliance have been focused putting together some resources on fall prevention ever since.

My dad was lucky and recovered quickly. Then, my sister and I came in and made some changes to his flooring and bathroom and gave him a personal alarm, which, of course, he hates. :). There was a bit of a learning curve for me and pages like yours here Aging Resources really helped a lot.

So I’ve prepared a Fall Prevention Toolkit, including your resources.

Judy - USA (28955)

Answer

I'm glad the Aging Resources on fall prevention have been useful to you and your father. It is a good idea of having a Fall Prevention Handbook for others to use.

Best wishes for success with your handbook and for the good health of your father.

Business

February 25, 2019

Question

Hi,

I hope you don't mind me reaching out! I'm looking into starting my own side business and was just reading through your business resources – super helpful, thanks for listing these :-)

I wanted to recommend an article, if you're open to it. Because I'm looking to start something with little to no investment, I found this list of low cost business ideas (shopify.com/blog/low-investment-business-ideas) super intriguing. I didn't see anything like this on your resource page so I figured I'd share in case your visitors could find it helpful.

Thanks again!
Jen

Jennifer - USA (28954)

Answer

Thanks for the resource. I added a link to it in Entrepreneurship Resources and eCommerce Resources.

Best wishes for success in stating your business.

What causes seeing into the future?

Senses

February 23, 2019

Question

When I was little I was able to see people in the future die. Mostly people I know. About 5 yrs ago I saw my grandmother in my sleep within 1 yr later she passed away. I still have these. I have seen them involve family and friends. I just would like to know what's causing this.

Brian - USA (28951)

Answer

Apparently, everyone has the ability to sense future events, although this sense is very weak. Some people seem to have this sense stronger than others. They may see possible future events in their dreams or even by just getting a "feeling" about it.

It can be disturbing.

One example of someone having such a dream happened with Abraham Lincoln. Days before he was assassinated, he had a dream that he had been killed. He told his wife about it.

It also seems that younger people have this sense more than older ones. I used to see some future events when I was younger but don't seem to do so much anymore.

Procedure for doing experiment

Experiments

February 23, 2019

Question

What are the procedures and precautions required for carrying the experiment of ""determining the coefficient of static friction using the scale pan method""

Favour - Nigeria (28952)

Answer

The coefficient of static friction is the resistance just before the object starts sliding. You must gradually pull on the object with your spring scale, so that it does not start sliding. You can observe the force on the object by watching your scale indicator.

Of course, if the object slides easily, it may be very difficult to get an accurate reading, so you may have to try several times.

I hope that helps. Best wishes in performing your experiment.

Relationship between math and science

Physics

February 13, 2019

Question

What is the relationship between maths and science with example?

lesa - Zambia (28942)

Answer

You can learn about the various sciences with no mathematics at all. However, if you want to measure effects and make predictions, you need to use mathematics to make the calculations.

For example, you know that a ball will fall to the ground due to the force of gravity. That is science and physics. But if you want to know how long it takes to hit the ground from a certain height, you need to use the formula and make the calculations with the math.

I hope that helps your understanding. Best wishes for success in your studies.

Evaluation of curriculum

Education

February 12, 2019

Question

With an adequate example, examine the statement "evaluation curriculum is the last process."

Patrick - Nigeria (28939)

Answer

It is important for the teacher to evaluate whether the curriculum has been effective in educating the students according to the goals of the class.

If many students fail an exam, the teacher must determine whether the curriculum was too difficult for this level of students, whether the material was poorly taught, or whether the test was too difficult.

Even before this, getting feedback from students and from other teachers is important in determining how well the material is taught.

I hope that helps. Best wishes for success in teaching students.

Solve for R-values

Physics

February 3, 2019

Question

How did you solve for the R values?

Eron - Philippines (28935)

Answer

An R-value is the capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power.

An article that explains how to calculate the R-value is: What Does R-Value Mean?

I hope that helps.

Is brick a better insulator than wood?

Physics

February 1, 2019

Question

Is brick a better insulator then wood?

Tyler - UK (28932)

Answer

Since brick is very solid, it is not really a very good insulator. On the other hand, wood is a good insulator. For some information, see Brick Homes vs Wood Homes.

Properties of good insulators

Physics

February 1, 2019

Question

what are some good properties of good insulators.

ruben - USA (28933)

Answer

Certainly, a good insulator should hinder outside heat transfer (hot or cold). But also, the insulator must not weigh too much or take up too much space.

Doppler effect

Physics

January 31, 2019

Question

What will happen if object travels at half the speed of light. Is doppler effect applicable for electromagnetic waves?

Pankaj - India (28930)

Answer

An object must travel at about 90% the speed of light for any noticeable effect. See Speed of Light for information.

Also see Doppler Effect Equations for Light.

I hope that helps your understanding.
