Answer:
The speed of bullet is 354.2 m/s
Explanation:
initial temperature, T = 30 degree C
specific heat, c = 128 J/kg K
Latent heat, L = 24.7 x 1000 J/kg
melting point = 600 K = 327 degree C
Let the mass is m and the speed is v.
Kinetic energy = heat used to increase the temperature + Heat used to melt

The answer to this question would be <span>Electrocautery Device
In a hospital, the device that can cause arc flash would be electrocautery device and circuit breaker. In fact, the electrocautery device uses the arc flash principle to work. The arc flash causing burns that surgeon use to clot bleeding in surgery or to destroy a tissue.</span>
The summary of the step you might use to carry out an investigation using scientific method include:
- Observation
- Hypothesis
- Experiment
- Conclusion
<h3>What is Scientific method?</h3>
This is defined as a systematic approach which helps to predict how several elements in the universe works.
This usually starts with observing a phenomenon and making a hypothesis. This is usually followed by conducting experiment to ascertain its authenticity before a conclusion is drawn.

the answer should be "fluids".
Kinetic energy can be used to develop electric energy which can be used as electricity.
<u>Explanation:</u>
The kinetic energy can be harnessed; much like some hydro power technologies harness water movement. A way to convert this kinetic energy into electric energy is through piezoelectric. By applying a mechanical stress to a piezoelectric crystal or material an electric current will be created and can be harvested.
Kinetic energy is also generated by the human body when it is in motion. Studies have also been done using kinetic energy and then converting it to other types of energy, which is then used to power everything from flashlights to radios and more.
