What is the working principle of an electric generator?
The generator is composed of a coil with many copper wires coiled around an iron core that is rectangular in shape. The armature is the term for this coil. This armature's purpose is to boost the magnetic flux. The armature revolves between two powerful permanent magnets that have been set. Here, the magnetic lines that are created are orthogonal to the axis of the armature. Two slip rings are further attached to the armature's arms. Two metallic brushes are also linked to the slip rings, which aid in moving current from the armature to the slip rings. These rings are employed for creating moveable contact. Last but not least, the current flows via a load resistance that is wired in parallel with and across the two slip rings.

While taking measurements using the uv-vis spectrometer, if the absorbance reading of a sample is more than _____, we will have to dilute the sample and collect a lower absorbance reading.
If a sample's absorbance reading is higher than 1.0 when being measured with a UV-vis spectrometer, it must be diluted in order to obtain a lower absorbance value.
The logarithm of light transmission (T) through a sample is known as absorbance. Transmission is the difference between the amount of light that passes through a sample and a blank in intensity (I) (Io). Thus, absorbance equals log (Io/I).
At an absorbance of 2, you are at 1%T, which denotes that the sample is blocking (absorbing) 99% of the light that is available. When you have an ABS of 3, you are at 0.1% T, which means that the sample is blocking (absorbing) 99.9% of the light that is available. These ranges fall outside of spectrometers' useful range.

An object has a 2 c charge. the object breaks into two pieces. one piece has a charge of -5 c is 7
What is charge?Charge is the traveling longitudinal wave energy. Mass and charge are the indeed related and can be simplified to a single energy equation. To relate mass and charge, Coulombs can be explained as the wave amplitude, which is measured as a distance (meters). If one assumes a substance in vacuum of space that has a physical property of kilograms, and moves as waves, then mass and charge can be described as their motion. In EWT, this substance is referred to as the ether and its components as granules.
Let's call Q the initial charge of object, which is:
Q=2c
When it breaks, two pieces will have charge and , and since the total charge must be conserved, the sum of these two charges must be equal to the initial charge of the object:
Q=Q1+Q2
We also know charge of one of the two pieces:

if you shout into the grand canyon, your voice travels at the speed of sound (340 m/s) to the bottom of the canyon and back, and you hear an echo. how deep is the grand canyon at a spot where you can hear your echo 5.2 seconds after you shout? [hint: think about the path the sound has to travel for you to hear your own echo.]
The Grand Canyon is 884 m deep from the spot where I heard the echo
The formula for uniformly rectilinear motion (URM) and procedure we will use to solve this exercise is:
v = x /t
Where:
x = distancet = timev = velocityInformation about the problem:
t(echo) = 5.2 sv= 340 m/sx = ?Notice that the echo is a sound that is produced when its wave hits an object (Grand Canyon) and returns to the place where it was emitted (person), that is to say that to calculate the time in which the echo arrived effectively to the bottom of the canyon we must divide it by 2.
t(canyon's bottom) = t(echo)/2
t(canyon's bottom) = 5.2 s/2
t(canyon's bottom) = 2.6 s
Applying the velocity formula, and isolating the distance, we get:
v = x /t(canyon's bottom)
x = v * t(canyon's bottom)
x = 340 m/s * 2.6 s
x = 884 m

you walk 3 km due east, then 2.5 km due south, then 11 km due west. how far are you from your start position?
If you walk 3 km due east, then 2.5 km due south, then 11 km due west, then you are 9.34 km far from the starting point.
Pythagoras theorem applicationIf you connect all the paths, it will make a triangle. If you join your current position with the start position, then you get the triangle ADE.
This question can be solved by using the application of Pythagoras theorem.
This theorem states that in a right-angled triangle, square of longest side is equal to the sum of the individual squares of the other two sides
Here, AD is the same as BC = 2.5km
and then EC = 11km and DC = AB = 3km
ED= EC-DC = 9 km
In the triangle ADE, according to Pythagoras theorem,
AE^2 = AD^2 + ED^2
so, AE = sqrt (9^2 + 2.5^2)
⇒ AE= sqrt (81 + 6.25)
⇒ AE = 9.34 km

if you double your driving speed what happens to your stopping distance (the distance it takes to stop the car)?
If you double your driving speed, then the stopping distance will be four times the original.
What is the equation of motion?Equations of motion are equations that describe a physical system's behavior in terms of its motion as a function of time. Equations of motion, The three equations of the motion are,
v - u = atS = ut + 0.5(at²)v² - u² = 2aswhere
S is the distance,
u is the initial velocity,
v is the final velocity,
t is the time,
a is the acceleration.
Given that the car is traveling at a speed and is needed to be stopped, therefore, the car will deaccelerate. Also, the final velocity of the car will become 0. Therefore, we can write,
v² - u² = 2as
Substitute the values,
Final velocity, v = 0Initial velocity, u = uDistance covered, s = s₁Acceleration, a = -aTherefore, we can write,
v² - u² = 2as₁
(0)² - u² = 2(-a)s₁
-u² = -2as₁
u² = 2as₁
s₁ = u² / 2a
Now, if you double your driving speed. Therefore, we can write,
v² - u² = 2as
Substitute the values,
Final velocity, v = 0Initial velocity, u = 2uDistance covered, s = s₂Acceleration, a = -aTherefore, we can write,
v² - u² = 2as₂
(0)² - (2u)² = 2(-a)s₂
-4u² = -2as₂
4u² = 2as₂
s₂ = 4u² / 2a
Since u²/2a is equal to s₁, therefore, we can write,
s₂ = 4(u² / 2a)
s₂ = 4(s₁)

For getting the mass of the truck, we have to just multiply the volume with the liquid density given and then add up the empty truck mass with it.
What is liquid density?A liquid's density is a gauge of how heavy it is relative to the amount being measured or in simpler terms, the density of any kind of liquid is a measure of how much heavy it is for the amount measured.
Any kind of liquid that weighs heavier is termed denser if you weigh two liquids with similar volumes or amounts. A substance which is less dense than water will float if it is gently put on the water's surface.
Just like any kind of solid, the density of a liquid will be equal to the mass of the liquid divided by its volume. i.e., D = m/v.
Mass of the truck = (Volume x liquid density) + empty mass of the truck

a 1.7 μc charge and a 2.5 μc charge are 12.5 cm apart. find a point where the electric field is zero.
The point where the electric field is zero is situated at a distance of 0.056 meters or 5.6 centimeters from the 1.7 uC charge.
The electric field(E) due to a charge is given by the formula,
E = KQ/r^2
For a point where the electric field is zero, the magnitude of the field due to two charges should be equal so that they cancel each other
Hence, the field produced due to 1.7 uc at the point should be equal to the field produced by the 2.5 uc charge.
Let the distance of the point where the electric field is zero be x from the 1.7 uc.
So, the distance of the point where the field is zero will be (0.125 - x) from 2.5 uc.
K(1.7uc)/x^2 = K(2.5uc)/(0.125 - x)^2
Solving the above equation
x comes out to be 0.056 meters or 5.6 centimeters.
Hence, The point where the electric field is zero is situated at a distance of 0.056 meters or 5.6 centimeters from the 1.7 uC charge.

The point where the electric field is zero is situated at a distance of 0.056 meters or 5.6 centimeters from the 1.7 uC charge.
The electric field(E) due to a charge is given by the formula,
E = KQ/r^2 equation 1
For a point where the electric field is zero, the magnitude of the field due to two charges should be equal so that they cancel each other
Hence, the field produced due to 1.7 uc at the point should be equal to the field produced by the 2.5 uc charge.
Let the distance of the point where the electric field is zero be x from the 1.7 uc.
So, the distance of the point where the field is zero will be (0.125 - x) from 2.5 uc.
Substitute the values of charges in equation1 and equate the equations for two different charges,
K(1.7uc)/x^2 = K(2.5uc)/(0.125 - x)^2
(1.7uc)(0.125 - x)^2 = (2.5uc) x^2
On simplifying the above equation
x = 0.056 meters or 5.6 centimeters.
Hence, the point where the electric field is zero is situated at a distance of 0.056 meters or 5.6 centimeters from the 1.7 uC charge.
