Different ranges of sound
Senses
March 1, 2019
Question
Which two animals can hear almost a completely different ranges of sound?
a)Humans and dogs
b)mice and frogs
c)dogs and cats
d)mice and cats
Shaikh - USA (28959)
Answer
You should be able to find out from the chart in Hearing Pitch or Sound Frequencies.
The hearing range of frogs and mice seems to be the most different.
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.
Suggested resource
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.
Real world example
Machines
January 28, 2019
Question
on youtube there is a 94 year old man using a tool called OTLVISE and He moves 300 lbs up stairs by Himself with it... Using a real world example teaches better the use of a simple machine as it uses a lever, wheels and a clamp with offset ergonomic handles.
john - USA (28925)
Answer
That sounds like an interesting device. Apparently, it is also used to move pool tables.
Time to reach the ground
Physics
January 27, 2019
Question
I have seen an equation to calculate time of an object to reach the ground as
t=?2h/g
Can you please help understand how this equation has come
Srinivasan - India (28924)
Answer
The time it takes a falling object to reach the ground is t = SQRT(2h/g) where h is the height or distance to the ground.
See Gravity Time Equations for Falling Objects for information.
I hope that helps.
