The ratio of the intensity of the second-order side maximum to the intensity of the central maximum is 1/4.

In a single-slit diffraction pattern, the intensity of the central maximum is given by the equation:

I(central maximum) = (A^2) * (b^2) / 4λ^2

where A is the amplitude of the wave, b is the width of the slit, and λ is the wavelength of the light.

For the second-order side maximum, the intensity is given by:

I(second-order side maximum) = (A^2) * (b^2) / 16λ^2

To find the ratio of the intensity of the second-order side maximum to the intensity of the central maximum, we can divide the two equations:

I(second-order side maximum) / I(central maximum) = ((A^2) * (b^2) / 16λ^2) / ((A^2) * (b^2) / 4λ^2)

Simplifying the equation, we get:

I(second-order side maximum) / I(central maximum) = 1 / 4

The maximum current that can be drawn from the battery without the terminal voltage dropping below 8.90 v is 75 A.

To calculate the maximum current that can be drawn from the battery without the terminal voltage dropping below 8.90 V, we need to use the equation: `V = E - Ir`, where `V` is the terminal voltage, `E` is the electromotive force, `I` is the current, and `r` is the internal resistance of the battery.Rearranging the equation, we get: `I = (E - V)/r`Substituting the given values, we get: `I = (9.00 V - 8.90 V)/0.012 Ω`I = 8.33 ΩΩ, or 75 A (rounded to the nearest whole number).Therefore, the maximum current that can be drawn from the battery without the terminal voltage dropping below 8.90 V is 75 A.

We know that the internal resistance of the battery is 0.012 Ω and the electromotive force is 9.00 V. The formula used to calculate the maximum current that can be drawn from the battery without the terminal voltage dropping below 8.90 V is I = (E - V)/r.Here, E = 9.00 V, V = 8.90 V, and r = 0.012 Ω.I = (9.00 V - 8.90 V)/0.012 ΩI = 83.3 ΩΩRounding off to the nearest whole number gives the answer of 75 A. Therefore, the maximum current that can be drawn from the battery without the terminal voltage dropping below 8.90 V is 75 A.

Electric current is a stream of moving electrons.

The number of electrons that leave a point has to be the same as the number of electrons that arrive there.

. If they arrive and don't leave, then there has to be a way to store them there, like a capacitor or a battery.

And if they're leaving but not arriving, then there has to be a tiny factory there, manufacturing electrons and shipping them out.

The whole idea is called "Conservation of electric charge". The idea is that charge can't be created or destroyed. If charge appears, it had to come from somewhere. And if you have some that you don't want, you have to send it somewhere, because it never just disappears.

There's actually a law in electronics that covers this nicely, called Kirchhoff's current law. It says that the sum of all currents entering a single point is zero. (current coming in is positive, current going out is negative). In other words, All current In and all current Out are equal.

Explanation:

The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects. Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared.

Answer:

No.

Explanation:

if it's in equilibrium then the torque or moment of inertia on both sides should cancel.

Torque is a vector quantity, force times distance.

When doing these, make sure your units are the same by changing centimeters to meters first.

Left side is 400N * (-2.5m) = -1000 Nm

Right side is 300N * (3.5m) = 1050 Nm

-1000 Nm + 1050 Nm does not equal zero so there's a torque on the teeter and it will rotate clockwise. The system is not yet in equilibrium.

Answer:

Ionic.

Explanation:

To know the the correct answer to the question given above, let us define the terms covalent and ionic.

Covalent is the term used to characterise a compound which is formed by sharing of electrons between the atoms involved. Thus, the compound formed is called covalent compound.

Ionic is the term used to characterise a compound formed when there is a transfer of electron(s) from the metallic atom to the non-metallic atom. The compound formed is called ionic compound.

Considering the question given above, since the calcium atom transfer electron(s) to the carbon atom, it means the compound is an ionic compound.

Acceleration of this helicopter is: 7 m/sec².

Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route. In other words, although velocity is a vector, speed is a scalar quantity.

Given that,

Initial Speed :- 25 m/s

Final Speed :- 60 m/s

Time :- 5 sec

Now by using motion equation ..

v = u + at

60 m/sec = 25 m/sec + (a × 5 sec)

or, 5a = 60 - 25

or, a = 35m/sec /5 sec

or, a = 7 m/sec²

Thus, acceleration of this helicopter is: 7 m/sec².

Explanation:

Given forces with magnitude F and F

Applying the parallelogram law of vector

Where resultant is given as :

R = √(A^2 + B^2 + 2ABCos Ф

WHERE A and B are two forces with angle Ф

F =√(F^2 + F^2 + 2F * F Cos Ф

Square both sides

F^2 = F^2 + F^2 + 2F^2 CosФ

F^2 - 2F^2 = 2F^2 CosФ

- F^2 = 2F^2 Cos Ф

Divide both sides by 2F^2

- 1 / 2 = CosФ

Cosine(theta) = - 1/2

Ф = cosi^-1 (-1/2)

Ф = 120°

The kinetic energy of the skater will be increase, but the angular momentum of the ice skater will be conserved.

Kinetic energy is the term used in physics to describe the force that a moving item has. It is described as the amount of effort necessary to accelerate anybody with a particular mass from rest to a given velocity. Except variations in speed, the body retains the kinetic energy it gains during acceleration.

The body uses exactly the same amount of energy when slowing down from its current rate to a state of rest. Formally, kinetic energy refers to any term in a system's Lagrangian that has a derivative with respect to time.

As the speed of the spin gets faster by pulling her arms then if the velocity is increasing then the kinetic energy will also increase, but the angular momentum will be conserved.

The youngest material on the alien planet's north pole would be the layered material that overlaps the cratered surface.

The youngest material, we can consider the principle of superposition. According to this principle, in undisturbed rock layers, the youngest layer is found on top, while the oldest layer is found at the bottom.
In this case, the layered material overlaps the cratered surface, indicating that it was deposited after the craters were formed. This means that the layered material is younger than the craters.
By analyzing the layering and its position relative to the craters, scientists can study the different layers of the planet's surface and gain insights into its geological history. The overlapping layered material provides valuable information about the planet's past geological events and processes.
It's important to note that without additional information or specific geological context, it may not be possible to determine the exact age of the material or the specific composition of the layers. However, based on the information provided, we can conclude that the layered material is the youngest.
