. Make a presentation to show what/how energy conservation
measures can be used for lighting controls and to save energy. (You
can do net and literature based research here but answer in your
own words with proper references)
(please w type it and make it in points)
Discuss the importance of resource conservation and renewable
energy. What environmental stewardship approaches can be used at
the community, national, and international level to promote
environmental sustainability. What practices can you adopt to
reduce your ecological footprint?
For a Baliistic Pendulum lab;
Describe in words how you used conservation of energy in this
lab. You must also expain why you were able to use conservation of
energy for this part of the problem.
Everyday lighting takes a lot of energy and comparison with
sports can be illustrative.
a) How much energy is consumed by a 60 W lightbulb if it’s
turned on for only 1 min?
b) If a kicked soccer ball had this much kinetic energy how fast
would it be moving in miles per hour?
c) How long would it take a ball moving at this speed to cross
the 100m soccer field?
d) Realistically a soccer ball might be kicked...
The law of the conservation of energy states that energy can
neither be created or destroyed within a closed system, but we also
know that any transfer of energy is not 100% efficient and some
energy “escapes”. Write briefly about the transfer of energy within
our cells …. how do we obtain, store, and use energy? Be sure to
give specific examples of the way we convert chemical energy to
mechanical and transport/potential energy within the cell. Also
address how...
describe 5 ways to be sustainable in a restaurant and how these
measures can save costs at the same time.
For example, do not turn on every equipment in the kitchen when you
first come in the restaurant in the morning. Only turn on what is
needed for the next few hours. How does that save cost? It saves on
energy costs such as gas and electricity.
How do you get this information? Research the topic on the
Internet. The...
1. Can one use energy conservation with electricity
concepts?
2. Write down a phenomenon that involves potential or potential
difference?
3. How is potential in static electricity related to potential
in current-carrying circuits?
