state two factors that affect the type of Shadows formed ​

Answer:

Energy cannot be created or destroyed (it can only change forms).

Explanation:

This is the definition of the law of conservation of energy.

The absence of external forces will make the pucks move in the form of a uniform circular motion.

It should be noted that a circular motion simply means the movement of an object along the circumference of the circle.

In this case, the absence of external forces will make the pucks move in the form of a uniform circular motion.

If the friction is absent, the pucks will continue to move on the same path due to the first law of Newton and the law of conversation of energy. In this case,the results will match the predictions until there's loss in energy.

The rotational inertia about an axis tangent to the sphere of the given mass and radius is ⁷/₅MR².

According to parallel axis theorem, the moment of inertia of a body about any axis is equal to the sum of the product of its mass and the square of the distance between the two parallel axis and the moment of inertia of the body about a parallel axis passing through its centre of mass.

The moment of inertia of the sphere about its parallel axis passing through its centre of mass = ²/₅MR²

The product of its mass and the square of the distance between the two parallel axis = MR²

Moment of inertia about an axis tangent to the sphere = MR² + ²/₅MR²

                                                                                           = ⁷/₅MR²

When an atom becomes electrically charged the number of electrons or protons stops and they are not equal again. The "extra" electron or proton is not balanced by something inside the atom any longer and it starts attracting itself to othet protons or electrons in other atoms.

An atomic structure comprises of positively charged nucleus which is surrounded by negatively charged particles called electron and neutron which is neutral charged.

Unlike charges attract each other while like charges repel each other.

Therefore, When an electron is fully charged, the number of electrons will stop to be unequal again.

This one is leisure for people with common sense. Yellow is an assortment of two of the rudimentary colors, red and green. Yellow appears yellow because red light is being imaged in our eyes, so that's one thing. Green reflections are capable of being enthralled by the shirt; hopefully, this should be meticulous adequate for you to have a basic understanding of this "phenomenon". Cheers!

A yellow T-shirt appear yellow to human eye because it reflects both red and green lights and our eye detects it as a combination of two fundamental colors (red and green), which is yellow.

Color is a perception. Our eyes sense something (the sky, for instance), and information is transferred from our eyes to our brains informing us that it is a particular color (blue). Different combinations of wavelengths of light are reflected by objects. When our brains detect certain wavelength combinations, they transform them into the phenomena known as color.

There has three fundamental color: red, blue and green. Red and green lights are combined to create yellow light. If a shirt reflects both red and green light, it appears yellow to human eyes. These two fundamental colors of light must be present in the incident light for red and green light to reflect yellow light to human mind.

We can determine the angular acceleration of the object by taking the slope of the line in the plot of angular speed versus time because the change in linear here.

The angular acceleration of an object is the measure of its rate of change in angular speed. Like the velocity, it a vector quantity and is characterized by a magnitude and direction.

The acceleration is the ratio of change in velocity to the time interval. From the graph of speed of an object versus the time taken, we can obtain the acceleration.

For a linear relation between the two quantities, the slope gives their ratio. Therefore, here, the slop of the line from 0 to 2 seconds represents the fraction delta omega over delta t. Hence, option D is correct.
