Rescue workers even find it difficult to access energy for their electrical devices – because there
is power outage
. Some of these large-scale natural disasters are earthquakes, tornadoes, hurricanes, floods, etc.
What type of emergency situations could rescue workers?
Rescue workers might then find communication difficult because they cannot get energy to their electrical devices. Examples of emergency situations that could have this type of effect include;
Earthquakes, Floods, Hurricane, Landslide, Tsunami, and Tornadoes
.
How rescue workers can get energy to their electrical devices in these situations?
The rescue workers can get energy to the batteries in their equipment during
rescue missions by using a generator to convert the kinetic energy to potential energy
. Potential energy is then stored in the battery.
What is energy and why does it matter to the rescue team?
What is energy and why does it matter to the rescue team?
Power taken from other things
. It is important because they need energy to power their devices. How can the rescue workers get energy to the batteries in their equipment during rescue missions?
What types of emergency situations could rescue workers be in that would make it difficult for them?
Rescue workers even find it difficult to
access energy for their electrical devices
– because there is power outage. Some of these large-scale natural disasters are earthquakes, tornadoes, hurricanes, floods, etc.
What is one way that potential energy might be involved?
When something happens, energy is changed from one form into another. When you climb stairs, chemical energy in your food is changed into kinetic energy by your muscles, and into potential energy as
you raise your body against gravity
.
What energy source is the best option for the rescue team?
Human powered generators
are the best energy source for the rescue team as it doesn’t require any lengthy time consuming resource but only the power of single human being. Just like fossil fuels, the human power is a kind of renewable energy source that does no harm to the environment and can be used whenever required.
What is the best energy source for rescue workers?
Claim 2:
Human-powered generators
are the best energy source for the rescue team. Evidence 1: Solar cells transfer energy from the sun to a battery. Evidence 2: Human-powered generators can be used to transfer energy any time someone is there to turn the crank.
How do objects get energy amplify?
When something has the ability to make things move or change in the future. How do objects get energy?
Energy is transferred and/or converted from another object that already has energy
.
Can objects make their own energy?
Organisms cannot create their own energy
. Producers can make their own food, but the energy itself comes from the sun.
Can energy still?
As we know through thermodynamics,
energy cannot be created nor destroyed
. It simply changes states. The total amount of energy in an isolated system does not, cannot, change.
In what way can you harness the energy of your body to produce electricity?
1.
Blood flow
. A team of Swiss researchers led by biomedical engineer Alois Pfenniger are showing the world a promising glimpse of the future: microturbines implanted in human arteries. The microturbines work much like a hydroelectric power plant by using the flow of the bloodstream to generate electricity.
Why do you think this object has potential energy?
Gravitational potential energy is stored in the object
due to the potential for the force of gravity to move it and pull it towards the Earth
. The amount of stored potential gravitational energy depends directly on the mass of the object and, more importantly, its height above the ground.
What energies are potential?
- Gravitational potential energy.
- Chemical energy.
- Nuclear energy.
- Elastic potential energy, also called spring energy.
- Electrical potential energy especially in a capacitor.
Which energy source did you rank as the worst option for the rescue team Why?
Answer: The worst option of energy source for the rescue team would be –
nuclear, hydroelectric, combustion and fuel burning
all are worst option fro max to less worst.
Why is a human powered generator good?
Unlike fossil fuels, human power
can be a clean energy source
, which produces little or no air pollution and soil contamination. Moreover, the potential of human power increases as the human population grows, while all other energy sources need to be shared among an ever-growing amount of people.
