What are Newton's three laws of motion?

Newton's First Law of Motion, or the Law of Inertia, states that "every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." This means that there is a natural tendency for a moving object to keep moving, unless an external force interferes.\nAccording to the Second Law of Motion, acceleration is produced when a force acts on a mass. The greater the mass, the greater the amount of force required. Force equals mass times acceleration.\nThe Third Law of Motion states that for every force, there is a reaction force that is eq..

What happens when an atom loses an electron?

All atoms tend to seek to be stable, which occurs when they have a neutral charge. When atoms don't have a complete outer orbital of electrons they will have a negative or positive charge. In order to become neutral, they will seek to either gain new electrons or lose electrons through bonding. In general, metal atoms often have excess electrons and will try to donate them through ionic bonding. Non-metal atoms typically need more electrons and will either accept them from metals or share electrons with non-metals through covalent bonding.

What protects the brain?

The human skull has 22 bones. Eight bones enclose the brain and make up the cranium. These are the occipital bone, which is found at the back of the skull, and the sphenoid, which is found at the base of the skull. There are two parietal bones at the top and sides of the skull. The frontal bone is found at the forehead and the ethmoid bone is found at the nose. The other bones of the skull are the facial bones. In an adult, the bones unite in hard, zigzag joints called sutures. In babies, these places are still open and soft.\nThe meninges are divided into the dura mater, the pia mater and th..

What is basic lava?

Due to its fluidity, basic lava typically releases volcanic gas before it builds up enough pressure to become explosive. When basic lava solidifies, it creates basalt rock in either tall six-sided columns or billowy masses. Basic lava typically creates dome-shaped volcanoes of low height, with a prominent example being Mauna Loa in Hawaii.

What type of ion forms when an atom loses electrons?

According to the octet rule, atoms seek to gain or lose electrons to achieve eight electrons in their outermost energy levels, which is the maximum allowable number of electrons in these energy shells and the most stable form of an atom. Elements on the periodic table that have the maximum number of electrons in their outermost energy levels are the noble gases. These elements are the most stable of all elements, and they are reluctant to form compounds with others. All other elements wish to mimic the noble gases in terms of electron configuration.\nAtoms that have few electrons in their oute..

Why do onion cells lack a chloroplast?

Although cells at the very top of the bulb that peek through the soil may develop chloroplasts, the main function of these cells is to protect the plant against harmful pathogens in the soil and to store energy. These functions are made possible by the cell wall, cell membrane, cytoplasm, nucleus and large vacuum of the cell.\nLight microscopy renders the nucleus of an onion cell visible at the edge of the cytoplasm. The vacuole is visible in the middle of the cell. This vacuole is transparent in the cells of white onions, making them invisible to light microscopy unless they are stained. Cell..

How is chemistry used in everyday life?

Every day people use different household products like bleach, ammonia, soap and detergents. These products are all made through different chemical reactions. For example, the making of soap is a chemical reaction that requires the heating of fats or oils and causing a reaction with an alkali to produce soap and water. The process is called saponification.The foods people prepare contain substances like baking soda and vinegar, which are examples of a base and acid, respectively. Salt, which is sodium chloride, is another substance used in cooking. Likewise, the medications and drugs that peop..

Why are agar plates turned upside down when incubated?

Agar plates are Petri dishes that contain a medium suitable for culturing microorganisms. They may also be called blood agar plates when they contain red blood cells, often from a horse or sheep, which are often used as a nutrient. Because some bacteria can only digest red blood cells that have already been broken down, some agar plates contain a preheated medium, which breaks down the blood cells and gives them a brownish color. This is often referred to as "chocolate agar" because of its color, and it does not reflect the presence of chocolate as a growth medium.Agar plates may also contain ..

What types of solar products get the most complaints?

There are solar energy companies that also get negative reviews and complaints from customers, notes ConsumerAffairs.com. Customers of these companies may complain primarily about the customer service and poor installation of solar panels.One company on Consumer Affairs with more than 100 reviews and a two star rating is Vivint Solar. Customers of this company complain that they can never get answers to questions about their panels through phone calls. They have also complained about their panels not being installed properly and damage being done to the roof in the process.Another company with..
