It is a metal because is saying that is a manually device
Answer & Explanation:
"The force <em>on a cutting tool</em> are 2600N vertically downward" sounds a little unusual, since most of the time, the tool is above the object to be cut in such a way that the force acting "ON the tool" is upwards. We will accept the statement as it is (downwards).
Since the two forces are acting at right angles to each other, the resultant can be found using Pythagoras theorem, namely
resultant = sqrt(2600^2+2100^2) = 3342 N (approx.)
The angle can be found using the arcTangent function, or
angle = arcTangent(2600/2100) = 51.07 degrees below the horizontal, since the 2600 N force is acting downwards.
Answer: b) They comprise at least two immiscible phases
Explanation: Nano composite coating are the coating that are the mixture of one or more phases that are irregular or immiscible in nature. They are in the nano- material form which helps in the improvement of chemical as well as physical properties. The phase that are usually present in nano composite coating are of nano crystalline phase or amorphous phase or two nano crystalline phases which are different from each other.
Answer:
mantle rocks begin to melt
Explanation:
melt when temperature raises, pressure lowers or water is added
1.) A semiconductor is a device whose conductivity lies between the conductivity of the conductors and the insulators.
2.) A Zener diode is a semiconductor device made of silicon that allows current to flow in both directions.
<h3>What is a semiconductor?</h3>
A semiconductor is a device whose conductivity lies between the conductivity of the conductors and the insulators.
Due to the inclusion of an impurity or temperature effects, a solid substance with conductivity between that of an insulator and that of most metals. Semiconductor devices, particularly silicon devices, are key components of most electronic circuits.
Zener diode:-
A Zener diode is a semiconductor device made of silicon that allows current to flow in both directions.
