Q: The only things that affect the period of a simple pendulum are its length and the acceleration due to gravity. the period is completely independent of other factors, such as this? Read this paragraph and choose the correct option from the provided answers: for the period of a simple pendulum. This result is interesting because of its simplicity. The only things that affect the period of a simple pendulum are its length and the acceleration due to gravity. The period is completely independent of other factors, such as mass. As with simple harmonic oscillators, the period T for a pendulum is nearly independent of amplitude, especially if is less than about. Choices: - size - rate - speed - mass A:
mass

Q: What layer of skin is located right beneath the epidermis? Read this paragraph and choose the correct option from the provided answers: The dermis is the lower layer of the skin, located directly beneath the epidermis (see Figure below ). It is made of tough connective tissue and attached to the epidermis by collagen fibers. The dermis contains blood vessels and nerve endings. Because of the nerve endings, skin can feel touch, pressure, heat, cold, and pain. The dermis also contains hair follicles and two types of glands. Choices: - cusps - scars - humus - dermis A:
(Answer)
dermis

Ques: Q: The structure of mitochondrion plays an important role in what? Read this paragraph and choose the correct option from the provided answers: The structure of a mitochondrion is defined by an inner and outer membrane. This structure plays an important role in aerobic respiration. Choices: - cell division - sexual reproduction - magnetism - aerobic respiration A:
Ans: aerobic respiration

Q: What term means opposition to the flow of electric charges that occurs when electric current travels through matter? Read this paragraph and choose the correct option from the provided answers: Resistance is opposition to the flow of electric charges that occurs when electric current travels through matter. The SI unit of resistance is the ohm (named for the scientist Georg Ohm, whom you can read about below). Resistance is caused by electrons in a current bumping into electrons and ions in the matter through which the current is flowing. Resistance is similar to the friction that resists the movement of one surface as it slides over another. Resistance reduces the amount of current that can travel through the material because some of the electrical energy is converted to other forms of energy. For example, when electric current flows through the tungsten wire inside an incandescent light bulb, the tungsten resists the flow of electric charge, and some of the electrical energy is converted to light and thermal energy. Choices: - polarity - antagonism - diffusion - resistance A:
(A).
resistance

Ques:Q: What is the electrode at which reduction occurs called? Read this paragraph and choose the correct option from the provided answers: The electrode at which reduction occurs is called the cathode . The cathode gradually increases in mass because of the production of copper metal. The concentration of copper(II) ions in the half-cell solution decreases. The cathode is the positive electrode. Choices: - reducthode - anode - cathine - cathode A:

Ans:cathode

Q: What method is used to map the earth on flat paper? Read this paragraph and choose the correct option from the provided answers: Earth is a round, three-dimensional ball. In a small area, Earth looks flat, so it is not hard to make accurate maps of a small place. When mapmakers want to map the round Earth on flat paper, they use projections. What happens if you try to flatten out the skin of a peeled orange? Or if you try to gift wrap a soccer ball? To flatten out, the orange peel must rip, and its shape must become distorted. To wrap a round object with flat paper requires lots of extra cuts and folds. A projection is a way to represent Earth's curved surface on flat paper ( Figure below ). Choices: - calculations - forecasts - surveying - projections A:
projections
