Answer : I hope this helps !
The Effort Force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted.
<h2>Answer: free electrons</h2>
<u>Plasma</u> is known as the 4th state of matter and is itself ionized gas. In this sense, ionization consists of the production of ions, which are <u>electrically charged atoms or molecules due to</u><u> the excess or lack of electrons</u><u> with respect to a neutral atom or molecule.
</u>
That is why in this process there are always<u> free electrons</u>. Therefore in heating gas to create plasma can yield free electrons, and the correct option is D.
Answer:
Explanation:Newton.s law of cooling states that the rate of cooling of an object is proportional to the difference between its own temperatures and temperature of its surroundings. Mathematically,
where is the heat transfer
is heat transfer coefficient
is the heat transfer surface area
is the temperature of the object's surface
is the temperature of the surroundings
Answer:
The maximum height reached by the toy rocket is 0.73 meters.
Explanation:
It is given that,
Mass of the toy rocket, m = 0.8 kg
It is projected at an angle of 45 degrees from ground level. The kinetic energy of the rocket is used to find the velocity with which it was projected as :
u = 10.12 m/s
When it reaches to a maximum height, its final velocity will be equal to 0, v = 0
Using third equation of motion to find it as :
a = -g
s is the maximum height reached by the toy rocket
In vertical direction,
s = 0.36 meters
So, the maximum height reached by the toy rocket is 0.73 meters. Hence, this is the required solution.
<span>Good Morning!
The oil is withdrawn from the subsoil through the extraction process. The first step is the detection of the reserves through equipment of probes and other detectors operated by satellite. This first stage is known as prospecting. Then the drilling begins, a process by which the soil layer that covers the reserve is violated in order to give access to the extraction equipment. This is then the last phase. At that time the oil pipelines are installed and the internal pressure of the earth plays the important role of "expelling" the oil from the soil, emanating it to the surface.
