What are 3 qualities of realism?

Yes! As long as both receive enough sun or wind to create electricity, you can use both solar panels and wind turbines to charge your battery bank by running through a hybrid charge controller.

Many renewable energy specialists believe that a tiny "hybrid" electric system that combines home wind and home solar (photovoltaic or PV) technology offers significant benefits over either one alone.

Wind and sunlight are inherently unreliable and energy inefficient. As a result, installing a lot of solar and wind energy equipment on the grid raises the price of electricity production, locks in the price of fossil fuels, and has a negative impact on the environment.

Due to the uniform distribution of leaves, folivores rarely exhibit dominance hierarchies.

A dominance hierarchy is a type of social hierarchy that arises when members of a social group interact, to create a ranking system. In social living groups, members are likely to compete for access to limited resources and mating opportunities. Rather than fighting each time they meet, relative rank is established between members of the same se x. Based on repetitive interactions a social order is created that is subject to change each time a dominant animal is challenged by a subordinate one. This hierarchical structure can be observed in many species, including humans.

The Philosophize Naturalis Principia Mathematica by Isaac Newton (1687) is the first work to explicitly state the cosmological principle.

Newton envisioned the Earth as a sphere in orbital motion around the Sun within an empty space that extended equally in all directions to impossibly enormous distances, in contrast to preceding classical or mediaeval cosmologies that saw the Earth as resting at the center of the universe.

The formal definition of the cosmological principle is "Viewed on a sufficiently wide scale, the properties of the cosmos are the same for all observers". This amounts to the firmly philosophical assertion that the cosmos as a whole, and not just the bit we can see, is governed by the same physical rules. In essence, this implies that the universe can be understood and is on scientists' side.

The cosmological principle has two testable consequences, an implicit qualification, and depends on a definition of "observer."

the internal enclosure wall is 539 K degrees in temperature. If a container has a 50 m2 interior space, the interior surface is black, and the container is kept at a constant temperature,

The answer solely depends on how well-insulated your house is. If your property is very well insulated, it is best to leave the heating on at a preset temperature, where thermostat and boiler can easily maintain the temperature because there is little heat loss.

Ohm's law states that temperature will remain constant, hence [heat] = vIt, where t is a constant. Since v and I are directly proportional, increasing v will likewise increase I, increasing v will result in an increase in heat (temperature).

In the field of physics, total internal reflection refers to the entire reflection of a beam of light that is traveling through a medium such as water or glass back into the medium itself from the surfaces that surround the medium.

When the angle of incidence is larger than a specific limiting angle, which is referred to as the critical angle, the phenomena will take place. When a ray of light traveling through a medium with a higher index of refraction approaches another medium with an angle of incidence that is greater than the critical angle, a phenomenon known as total internal reflection occurs. In general, this phenomenon takes place at the boundary between two transparent media.

True statements are;

1. A smaller critical angle means the total internal reflection is more likely to occur.

2. Fiber optic cables are practical applications of total internal reflections.

False statements are;

1. When light hits a boundary at a less than the critical angle, it will undergo total internal reflection.

2. Single reflection of light of a silvered mirror is more efficient than total internal reflection so mirrors are often used instead of prisms in optical instruments to minimize light loss.

Calcium is released by the action of osteoclasts which break down bone matrix.

The cells known as osteoclasts are responsible for breaking down bone to start the process of normal bone remodeling and for mediating bone loss in pathologic situations by escalating their resorptive activity. They develop in the bone marrow from progenitors in the myeloid/monocyte lineage, which then circulate in the blood. The Howship lacunae, which osteoclasts occupy on the surface of the bone, are assumed to be the result of the osteoclasts' enzymes eroding the bone. The union of many cells produced from blood-circulating monocytes results in osteoclasts. These are derived from the bone marrow in turn.

A simple compound microscope provides large magnification by employing a short focal length objective and a short focal length eyepiece.

A compound microscope is a high magnification microscope that uses two lenses to compound the level of magnification. The first lens is an objective lens and the second lens is an eyepiece lens.

In compound microscope both lenses are convex lenses. The objective lens has a very short focal length and hence has very high magnifying power (P ∝ 1/f ).

The image formed by the objective lens serves as the object to the eyepiece. The position of the eyepiece is kept such that the image formed by the objective lens is formed within the focal length of the eyepiece.

What is free fall?

Free fall is a concept of motion where an object is falling under the force of gravity and is only subjected to the force of gravity. It is experienced by objects that are not subject to any other type of force such as air resistance or drag. Examples of objects in free fall include an object dropped from a certain height, a skydiver in a belly-to-earth position, a spacecraft in orbit, or an object thrown upwards and then falling back down. A free fall can be thought of as a state of weightlessness, since the object is not subject to any other force, and is accelerating at a rate of 9.8 m/s2 (or 32 ft/s2). This acceleration is due to gravity and is known as the acceleration due to gravity.

Height from which the bullet id fired, h  = 0.981 m

initial velocity of the bullet, u₁ = 981 m/s

Since it is fired parallel to the ground , the initial velocity u₁ does not have a vertical component

So it will be a free fall

Therefore the time taken to reach ground , t =√(2h/g)

t = √(2 * 0.981 / 9.81)

Yes, Ballistic stretching can be harmful if it is not performed properly.

This type of stretching involves bouncing movements, which can place excessive strain on the muscles and connective tissues. This can lead to muscle strains or tears, as well as other injuries. It is important to use caution when performing ballistic stretches and to stop if any pain or discomfort is experienced. It is also recommended to warm up before stretching and to stretch slowly and smoothly, rather than using ballistic movements.

Ballistic stretching can also increase the risk of muscle imbalances and poor posture if it is not balanced with other types of stretching, such as static stretching. It is generally more effective and safer to gradually increase flexibility through regular, consistent stretching rather than trying to force the body to stretch too quickly or aggressively.
