How does a transistor work?
i need three examples !
Answer:
A transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon. ... By turning a small input current into a large output current, the transistor acts like an amplifier. But it also acts like a switch at the same time.

Suppose that the net external force (push minus friction) exerted on a lawnmower is 51 N. parallel to the ground. The mass of the mower is 24 kg. What is its acceleration?
Answer:
2.125 m/s^2
Explanation:
Use Newton's second law: Force equals mass times acceleration, F = ma. You know the force (51 N) and you know the mass of the mower (24 kg). Remembering that a Newton is the same as kg-m/s2, solve for acceleration:
F = ma
51 kg-m/s2 = 24 kg * a
2.125 m/s2 =a
If a net external force of 51N is extorted on a 24kg lawnmower parallel to the ground, the acceleration of the mower will be 2.125 m/s².
Given the data in the question;
Net External Force; [tex]F = 51N[/tex]
Mass of the Mower; [tex]m = 24kg[/tex]
Acceleration; [tex]a = ?[/tex]
To determine the acceleration of the mower, we make use of the equation from the Newton's Second Law of Motion:
[tex]F = m\ * \ a[/tex]
Where F is the force exerted, m is the mass and a is the acceleration.
But then, we know that; ( A newton is the same thing as [tex]1 kg.m/s^2[/tex] )
Hence, Our Net External Force; [tex]F = 51kg.m/s^2[/tex]
We substitute our values into the equation to find acceleration "a"
[tex]51kg.m/s^2 = 24kg\ *\ a\\\\a = \frac{51kg.m/s^2}{24kg} \\\\a = 2.125 m/s^2[/tex]
Therefore, If a net external force of 51N is extorted on a 24kg lawnmower parallel to the ground, the acceleration of the mower will be 2.125 m/s².

In the winter, people often buy large bags of rock salt to sprinkle on their walkways. Why do people do this?
Answer:
It helps melt the ice away on their walkway.
Explanation:
The salt makes the ice to freeze at a lower temperature. So when a solute (salt) comes into contact with the ice the freezing point is lowered.
What would the density of a liquid that has a mass of 275 grams and a volume of 200 mL?
Answer:
Mathematically: D = m/v. If you know what liquid you have, you can look up its density in a table. Once you know that, all you have to do to find the mass of the liquid is to measure its volume. Once you know density and volume, calculate mass using this relationship: mass = density • volume

scientific findings that prove the strong nuclear force exsist
Answer: The strong nuclear force is one of the four fundamental forces in nature; the other three are gravity, electromagnetism and the weak force. As its name implies, the strong force is the strongest force of the four. It is responsible for binding together the fundamental particles of matter to form larger particles
A hockey stick strikes a hockey puck of mass 0.17 kg. If the force exterted on the hockey puck is 35.0 N and there is a force of friction of 2.7 N opposing the motion. what is the acceleration of the hockey puck?
Choices:
0.0054 m/s^2
0.005 m/s^2
200 m/s^2
190 m/s^2
Answer:
[tex]a=190\ m/s^2[/tex]
Explanation:
Mass of a hockey puck, m = 0.17 kg
Force exerted by the hockey puck, F' = 35 N
The force of friction, f = 2.7 N
We need to find the acceleration of the hockey puck.
Net force, F=F'-f
F=35-2.7
F=32.3 N
Now, using second law of motion,
F = ma
a is the acceleration of the hockey puck
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{32.3}{0.17}\\\\a=190\ m/s^2[/tex]
So, the acceleration of the hockey puck is [tex]190\ m/s^2[/tex].
The magnitude of acceleration of the hockey puck is 190 m/s² .
Given data:
The mass of hockey puck is, m = 0.17 kg.
the magnitude of external force on the puck is, F = 35.0 N.
The magnitude of force of friction is, f = 2.7 N.
We need to find the net force acting on the puck first. For that consider the applied force in the x-direction. Then net force is,
F' = F - f
Solving as,
F' = 35.0 - 2.7
F' = 32.3 N
Now, use the Newton's Second law to obtain the magnitude of acceleration (a) as,
F' = ma
Solving as,
32.3 = 0.17 (a)
a = 32.3/0.17
a = 190 m/s²
Thus, we can conclude that the magnitude of acceleration of the hockey puck is 190 m/s² .

b. sulfur is not shiny and is not malleable
c. sodium is a solid at room temperature and reacts to other elements.
d. silicone is shiny and is a poor conducted of electricity
Answer:
d. silicone is shiny and is a poor conducted of electricity
The best option that describes an example of a chemical property of an element is silicone is shiny and is a poor conductor of electricity. Option D is correct.
The chemical properties of elements are those properties that are noticeable during the course of a chemical reaction.
Aluminum is solid but not at room temperature. The elements that are solid at room temperature are iron, zinc, gold, and silver. Hence option is incorrect. The same is applicable to options B and C.

Which statement about mass and inertia is not true?
A. Both mass and inertia play a role in Newton's first law.
B.Mass is a quantitative measurement of inertia.
C. The tendency of an object to remain at rest results from a property called inertia.
D.Newton's first law is sometimes called the relative inertia law.""
Answer:
D. Newton's first law is sometimes called the relative inertia law.
Explanation:
Newton's first law of motion states that an object at rest will stay at rest and that in motion will stay in motion with same speed and in the same direction unless an unbalanced force acts on it. It is also called the law inertia. Mass and inertia play a role in this law because mass is a quantity that mainly depends on inertia in that a body with more inertial will exhibit more mass.
