Answer:

of the net electric field at point P due to the two charges.

Explanation:

1 > 2 > 3 > 4 will be the order of the planets As per mass per unit volume and stats are given. As the density of the planet is directly proportional to its mass of the planet.

The force of attraction of two bodies is directly proportional to the products of their masses whereas it is inversely proportional to that of the distance between them here we use the constant Newton's gravitational Universal Constant.

So the more the mass more the attraction and more the distance the less attraction will be or vice-versa.

And shown in the Image attached how density is decreasing from planet 1 to planet 4 so the order of masses will also be the same.

The amount of the car's centripetal acceleration as it follows the curve given in the paragraph is -v2/r = a.

A force is an effect in physics that may modify the velocity of an item. A force can cause a mass item to change its velocity, or accelerate. Intuitively, force may be characterized as a push or a pull. A force is a vector quantity since it has both magnitude and direction. The term "force" has a specific meaning in science. At this level, it is quite acceptable to refer to a force as a push or a pull. A force is not something that an item possesses or possesses. Another item applies a force to another. The concept of a force is not restricted to living or non-living entities.

The moments of inertia are ranked as follows, from smallest to largest is     I₁ < I₂ < I₃.

Moment of inertia is a physical quantity that measures an object's resistance to rotational motion. It is defined as the sum of the products of the mass of each particle in a system and the square of its perpendicular distance from the axis of rotation.

The formula for moment of inertia is:

I = Σmr²

where I is the moment of inertia, m is the mass of each particle in the system, r is the perpendicular distance of each particle from the axis of rotation, and the symbol Σ indicates a summation over all particles in the system.

Moment of inertia plays a crucial role in rotational motion, just as mass plays a crucial role in linear motion. It determines how much torque is required to produce a certain amount of rotational acceleration, and how quickly an object will respond to an applied torque.

The moment of inertia of an object depends on its shape and the distribution of mass within that shape. Objects with more mass distributed farther from the axis of rotation will have a higher moment of inertia and will be more resistant to rotational motion.

Moment of inertia is an important concept in many areas of physics and engineering, such as the design of rotating machinery, the motion of planets and other celestial bodies, and the behavior of molecules in quantum mechanics.

Here in the question,

To rank the moments of inertia I₁, I₂, and I₃ about axes through the centers of the rods, we need to use the parallel axis theorem, which states that the moment of inertia about an axis parallel to an axis passing through the center of mass of the object is equal to the moment of inertia about the center of mass plus the product of the mass and the square of the distance between the two axes.

Let's denote the distances between the centers of mass and the rods as r₁, r₂, and r₃, respectively.

Then we have:

I₁ = I₁_cm + m(r₁ + R/2)^2

I₂ = I₂_cm + m(r₂ + 2R)^2

I₃ = I₃_cm + m(r₃ + R/2)^2

To rank the moments of inertia, we need to compare the values of (r + R/2)^2, (r + 2R)^2, and (r + R/2)^2 + R²/4 for each of the pairs of balls. We can see that the last term is the same for all pairs of balls, so we only need to compare the first two terms for each pair.

For pair 1, we have:

(r₁ + R/2)^2 < (r₂ + 2R)^2

since r₁ < r₂.

For pair 2, we have:

(r₂ + 2R)^2 < (r₃ + R/2)^2 + R²/4

since r₂ < r₃.

Therefore, the moments of inertia are ranked from smallest to greatest is I₁ < I₂ < I₃.

Systems thinking is a way of understanding how different components of a system interact with one another. In the case of a car, the systems thinking model can be applied to understand how different components work together to produce the desired outcome of driving the car.

Input: Gas - This refers to the fuel that goes into the car. The car cannot operate without fuel, so it is considered an input to the system.

Process: Engine - This is the component of the car that converts the fuel into energy, which powers the car. The engine is the process that takes place within the car to make it move.

Output: Pedal - This is what the driver uses to control the speed of the car. The pedal is the output of the car's movement, as it is what the driver uses to drive the car.

Feedback: Warning light - This is a mechanism that provides feedback to the driver about the state of the car. For example, if the gas tank is low, a warning light will come on, providing feedback to the driver that they need to refuel the car.

In summary, Systems thinking model can be applied to a car in order to understand the relationship between different components of the car.
