How could rescue workers use squeezing or compressing to get energy to their flashlights during rescue missions?

Answers

Answer:

Explanation:

During rescue missions, different types of energy can be devices for flashlight, this could be human powered energy such as squeezing or compressing. In flashlight electrical energy is converted to light and thermal energy.

A squeezing or compressing to get energy for flashlight can be regarded as "DYNAMO PROCESS" it involves spinning of "fly wheels" into the flashlight through consistent squeezing ,which is connected to a dynamo(Dynamo supply electrical current). Hence the needed light is seen on the bulb of the flashlight.

A squeeze flashlight or dyno torch is a form of mechanically powered flashlight that produces energy through the rotation of flywheel which then turns a dynamo or generator that powers an attached light emitting diode, LED or incandescent bulb when electric current is generated

Where there is need for artificial light, where direct electric power is not available, such as during a rescue operation, rescue workers can produce illumination by continuously pumping the dyno torch during the mission. The squeezing action causes the flywheel to turn, with the turning made to occur between each squeeze, by the flywheel. The rotational energy from the flywheel turns the generator, which produces steady lighting

Which of the following is an example of diffraction? A. Hearing a band play through an open doorway without seeing them. B. Sitting in a room and watching a band play. C. Playing in a band. D. None of these examples show diffraction.

Answers

A because diffraction is the bending of waves around small obstacles or openings. That’s why you can hear a band through an open doorway without seeing them

The potentially dangerous part of the electromagnetic spectrum is produced to generate power with nuclear energy A. Gamma Rays B.Radio Waves C.Microwaves D. Infrared Rays

Answers

Answer:A- Gamma rays

Explanation:

Gamma rays are most dangerous among all the given rays because it has the highest frequency i.e. high penetrating tendency. They can also pass through bones and teeth and this is the reason for their potential hazard.

They can destroy the living cell, initiate gene mutation and can cause cancer.

But they can also be used for destroying cancer cells.
