"MangFermin, a carpenter, is planing a piece of wood with his planar. After how many minutes, he observed that it is hot. What is the evidence that there is heat transfer?

a. It is not evident.
b. Hotness means there is an increase in the temperature.
c. Yes, hotness means there is a decrease in the temperature
d. No, hotness is not related to a change in temperature"

 

Answer:

When mang Fermin was using his planer on a piece of wood, he noticed that it was getting hot. What is the evidence of any heat transfer?

I believe that the answer is the letter (b), wherein hotness means there is an increase in temperature.

Explanation:

The movement of going back and forth with a planer on the piece of wood transforms kinetic energy to heat energy because the atoms in the material move and vibrate while Mang Fermin does his work. This causes friction to occur which then generates heat. Whatever heat there is can be most felt on the bottom side of the planer and the side of the wood that it was working on.  

It is worth noting that the level of heat produced is determined by the amount of pressure exerted by Mang Fermin on the planer and how long the back and forth motion takes place while he is working.

Bakit Kailangan Ang Ekonomiks

Bakit kailangan ang ekonomiks   Answer: Kahulugan ng ekonomiks Ang ekonomiks para sa mga hindi nakakaalam ay patungkol sa eksaktong pag-aaral ng mga pamamaraan sa kung paano nagbabahagi ang mga tao o mamamayan at bansa ng kanilang pinagkukunang-yaman na limitado lamang. Ito ay upang matugunan ang kanilang mga pangangailangan na wari ba ay walang katapusan. Sa madaling salita, maituturing ito na isang uri ng agham na tumatalakay pagdating sa produksyon at distribusyon ng yaman ng isang bansa. Sinusuri nito ang mga kilos at pag-uugali ng mga tao at pangkalahatang iniuugnay sa paggamit at pagkakamit ng mga pangunahing pangangailangang materyal ng tao. Ito ang mga pangunahing kasagutan sa kung ano ang ibig sabihin ng ekonomiks. Ngunit sa mata ng iba't-ibang ekonomista, ang kasagutan sa katanungan na kung ano ang kahulugan ng ekonomiks ay may iba't-ibang pagpapaliwanag na maaaring magbigay ng mga simpleng kahulugan ng ekonomiks.

Action Plan: How Will You Know When It Is Complete?

Action Plan: How will you know when it is complete?   Answer: First, any experiments need a time frame and goal. For this one, I will allot a 2 week time frame that can be extended up to 1 month. The goal is to help at least 80% of people who subscribed or followed us through our social media account. Second, we need to have a data that we can counter check if there are positive or negative results within the said time frame. This includes the interviews that well have from different people on how they usually cope up with stress and how our experiments worked or helped them achieve positive results after the two week period. Lastly, well need to have a computation from the data on how many percentage of people who subscribed had a positive outcome with the said videos or stories that weve shared through social media. When will we extend our time frame to a month?? - If we havent reached our percentage goal which is 80%. After the two week to one month time frame, once we achieved
