what does a resistor in an electrical dp
Answer:
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
Explanation:
Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components can be composed of various compounds and forms. Resistors are also implemented within integrated circuits.
The electrical function of a resistor is specified by its resistance: common commercial resistors are manufactured over a range of more than nine orders of magnitude. The nominal value of the resistance falls within the manufacturing tolerance, indicated on the component.

numerical filing method is more scientific why give me 4 reason
Answer:
Numerical Methods are mathematical way to solve certain problems.Whether the equations are linear or nonlinear, efficient and robust numerical methods are required to solve the system of algebraic equations.
Analytical solutions are exact solutions based on mathematical principles.
However, the governing partial differential equations of fluid flow are complex and cannot be solved by analytical means. The partial differential equations are therefore converted into a system of algebraic equations that are subsequently solved through numerical methods to provide approximate solutions to the governing equations.
Although we rarely reach on exact answer , we can get really close to the exact answer much quicker than solve analytically.

Calculate the acceleration of a bus that speed up from 20ms-1 to 40ms-1 in 8 seconds?
Answer:
2.5 ms^-2
Explanation:
acceleration
= (final velocity - initial velocity)/time
= [(40m/s) - (20m/s)]/8s
= (20m/s)/8s
= 5/2 m/s²
= 2.5 m/s²
= 2.5 ms^-2
an object is sliding down in clean plane the velocity change at a constant rate from 10 cm to 15 CM in 2 second what is it acceleration ?
Initial velocity=10m/s=u
Final velocity=v=15m/s
Time=t=2s
[tex]\boxed{\sf Acceleration=\dfrac{v-u}{t}}[/tex]
[tex]\\ \sf\longmapsto Acceleration=\dfrac{15-10}{2}[/tex]
[tex]\\ \sf\longmapsto Acceleration=\dfrac{5}{2}[/tex]
[tex]\\ \sf\longmapsto Acceleration=2.5m/s^2[/tex]
Answer: a = 2.5 cm/s²
Explanation:
Acceleration = (Final velocity - Initial Velocity)/time taken
a = v-u/t
Initial velocity = 10 cm/s
Final velocity = 15 cm/s
Time = 2 seconds
a = (15-10)/2
a = 5/2
a = 2.5 cm/s²
Therefore the acceleration is 2.5 cm/s²

The deflection plates in an oscilloscope are 10 cm by 2 cm with a gap distance of 1 mm. A 100 volt potential difference is suddenly applied to the initially uncharged plates through a 1075 ohm resistor in series with the deflection plates. How long does it take for the potential difference between the deflection plates to reach 65 volts
Answer:
20 ns
Explanation:
Since the deflection plates are in series with the resistor, the deflection plates act as a capacitor.
So, the set-up is a series RC circuit.
The voltage across the deflection plates V =
[tex]V = V_{0}(1 - e^{-\frac{t}{RC} } )[/tex]
where V₀ = voltage applied = 100 V, R = resistance of resistor = 1075 Ω and C = capacitance of deflection plates and t = time to reach 65 V
The capacitance of the deflection plates C = ε₀A/d where ε₀ = permittivity of free space = 8.854 × 10⁻¹² F/m, A = area of deflection plates = 10 cm × 2 cm = 20 cm² = 20 × 10⁻⁴ m² and d = distance between deflection plates = 1 mm = 1 × 10⁻³ m.
So, C = ε₀A/d
C = 8.854 × 10⁻¹² F/m × 20 × 10⁻⁴ m²/1 × 10⁻³ m
C = 177.08 × 10⁻¹⁶ Fm/1 × 10⁻³ m
C = 177.08 × 10⁻¹³ F
C = 17.708 × 10⁻¹² F
Since we require the time it takes the capacitor to reach 65 Volts, V = 65 and we make t subject of the formula,
So, [tex]V = V_{0}(1 - e^{-\frac{t}{RC} } )[/tex]
[tex]\frac{V}{V_{0}} = (1 - e^{-\frac{t}{RC} } )\\e^{-\frac{t}{RC} } = 1 - \frac{V}{V_{0}}[/tex]
taking natural logarithm of both sides, we have
-t/RC = ㏑(1 - V/V₀)
t = -RC㏑(1 - V/V₀)
Substituting the values of the variables into the equation, we have
t = -RC㏑(1 - V/V₀)
t = -1075 Ω × 17.708 × 10⁻¹² F㏑(1 - 65 V/100 V)
t = -19036.1 × 10⁻¹² ΩF㏑(1 - 0.65)
t = -19036.1 × 10⁻¹² ΩF㏑(0.35)
t = -19036.1 × 10⁻¹² × -1.0498 s
t = 19984.5189 × 10⁻¹² s
t = 1.99845189 × 10⁻⁸ s
t = 19.99845189 × 10⁻⁹ s
t ≅ 20 × 10⁻⁹ s
t ≅ 20 ns
So, the time it takes the potential difference between the deflection plates to reach 65 V is 20 ns.
a car is stationary at first.it moves off with.acceleration of 2m.s-2.Calculate how far it will move in 10s
Answer:
100 m.
Explanation:
At first the car was stationary, so its inicial velocity is zero. Considering its inicial position 0 m and using the Equation of motion for the position:
X(t) = Xo + vo.t +a[tex]t^{2}[/tex]/2 , vo=0, Xo=0, a=2m/[tex]s^{2}[/tex]
X(10) = (2 x [tex]10^{2}[/tex])/2 = 100 m.

The tin can with water in its bottom is heated to boil water and the steam is allowed to escape for some time. The open mouth is sealed with an air-tight cap and cooled under tap water. The tin can get crushed, why?
Explanation:
Water does expand with heat (and contract with cooling), but the amount of expansion is pretty small. So when you boil a can filled with water and seal it, the water will contract slightly as it cools. The can may kink slightly, but that will be it. Actually, most likely the only things you will be able to see is then top and bottom will be sucked in and go concave. Just like a commercial can of beans.
Now if you have a can with a little water and a big air space, things are completely different.
As the water boils, water vapour is given off. Steam. Let it boils for a minute just to make sure (nearly) all the air is expelled and the can is filled with steam.
Now when you put the lid on and cool the can, that steam condenses back to water, and goes from filling the can to a few drops of water. The can is now filled (if that is the right word) with a near vacuum, The air pressure, 15 lbs/square inch, will be pressing on every surface of the can, with nothing inside the can to resist it.
The can will crumple before your eyes.

Non-ideal behavior for a gas is most likely to be observed under conditions of a) high pressure and low temperature. b) high temperature and high pressure. c) high temperature and low pressure. d) standard temperature and pressure. e) low temperature and low pressure.
Answer:
high temperature and low pressure
Explanation:
Real gases have intermolecular forces of attraction between them hence they can be liquified. However, gases approach ideal behavior at high temperature and low pressure.
According to the kinetic theory of gases, gases molecules move at incredibly high speeds and exhibit no intermolecular interaction because the gas molecules are isolated from each other.
At high temperature and low pressure, gas molecules are found to possess maximum kinetic energy. They move with a very high velocity and have minimal intermolecular interaction between them in accordance with the proposition of the kinetic theory of gases.

Answer:
Explanation:
It was Newton's genius that saw that it was true. He also realized that if it was true, the motion the earth experience would be unmeasurably small, especially in his time. Their instruments were just not good enough: crude and too approximate would be better descriptions.

difference Between Newton's first law and third law of motion
Newton first law state that anything in motion or rest will remain in motion or in rest until an external force is applied
Newton third law of motion state that every action have equal and opposite reaction
Answer:
Newton's laws of motion relate an object's motion to the forces acting on it. In the first law, an object will not change its motion unless a force acts on it. ... In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
