What is oscillation ?

Oscillation is the process by which a quantity or measure varies in time around its equilibrium value. Another definition of oscillation is the periodic variation of a substance between two values or around its central value.

What is kinetic force?

A force that acts between moving surfaces is referred to as "kinetic friction." A force acting in opposition to the direction of a moving body on the surface is felt. The two materials' coefficients of kinetic friction will determine how much force is applied.

For both blocks to oscillate together w^2=K/((M+M))

Maximum accelartion =a_(n= w^2 ) A= K/((M+M))A

For ⏊ kg block, μmg = 〖ma〗(n= )  μg

μg =K/((M+M))A

= 0.45×9.8 = 150/((2.1+1)) A

A=0.0914m

Max speed, vm=wA=  √(k/(M+M)) A

=√(150/((2.1+1))) × 0.0914

= v(m=) 0.636 m/s

Therefore, the maximum speed is  0.636 m/s.

With an astronomical telescope, the angle of just resolution light from two stars would be greater if the light of the average star is red or if it is blue.

What is an astronomical telescope?

An astronomical telescope consists of two lenses: objective and eyepiece.

The objective lens forms the image of a far off object at focal point while eyepiece lens just magnifies the image and make it look more clear, visible and magnified.

The formula D = 1.22λ/dФ is used to find the value of aperture of the telescope.

In general, an astronomical telescope is used to view distant stars. Thus, the angle formed would be greater if the light emitted by the average stars is red or blue.

any procedure where velocity fluctuates

Any procedure where the velocity varies is referred to as acceleration. There are only two methods to accelerate because velocity is both a speed and a direction: changing your speed or changing your direction.

An object has positive acceleration if it is accelerating and travelling in the right direction. Positive acceleration was demonstrated in the first example by the speeding car. The acceleration is in the same direction as the car's motion because it is moving forward and speeding up.

Electrical power (P) can be defined as the sum of these two numbers if voltage (V) equals Joules per Coulombs (J/C) and amperes (I) = charge (coulombs) per second (A = Q/t). This is due to the fact that electrical power can also be expressed as P = V*I, or voltage times amperes.

Electric Power can be explained as:

Electric power is the rate at which electrical energy moves across an electric circuit. The SI unit of power is the watt, or one joule per second. The suffixes used to represent thousands, millions, and billions of watts are kilowatts, megawatts, and gigawatts, respectively. Watts are subject to the same standard suffixes as other SI units.

A power law is an equation in which, regardless of the initial sizes of the two values, a relative change in one quantity results in a corresponding relative change in the other.

The Equation:

What is magnitude?

Magnitude typically refers to size or distance. By comparing the size and movement speed of the object, we can relate magnitude to movement. The object's or quantity's size determines its magnitude.

What is displacement?

A one-dimensional quantity called displacement (symbolized as d or s), also known as length or distance, represents the separation between two specified points. The meter is the SI's (International System of Units) accepted displacement unit.

Given that the beginning displacement is 120 meters to the north, the ultimate displacement is 72 meters to the west.

R = (A2+B2)1/2 is the magnitude of the resulting vector A+B.

The angle formed with the west direction is = tan-1(A /B) when = 139.9428m.

The force constant k of the spring is 781000 N/m

What is force?

Once applied, force is described as an external cause that alters or tends to modify the state of the body; if the body is in motion, it comes to rest, and if at rest, it comes to motion. It can also induce a shift in the body's direction, shape, or size. Pushing or pulling a door with force is an example.

Because force is a vector quantity, it has both magnitude and direction. Newton's second law defines force as the "product of a body's mass and acceleration."

In physics, a force is an effect that can change the velocity of an object. A force can cause a mass object's velocity to change (e.g., moving from rest), causing it to accelerate. Force can be thought of as either a push or a pull. Because it has both magnitude and direction, force is a vector quantity. It is measured in newtons, the SI mass unit (N). The letter F stands for force (formerly P).

In its original form, Newton's second law states that the net force acting on an object is equal to the rate at which its momentum varies with time.

Here,

let the force constant is k

Using conservation of energy

0.50 * 5 *10^5 * 0.50^2 = 0.50 * k * 0.40^2
