Do gravitons have mass? Gravitons do indeed have mass, and their motions generate kinetic energy. Other particles have mass, but they are much larger, much less numerous, and cannot substitute for the gravitational effects which generate space curvature. The great mystery of so-called force at a distance is explained by the mass of gravitons. Are […]
What are the major steps in homeostasis?
What are the major steps in homeostasis? Adjustment of physiological systems within the body is called homeostatic regulation, which involves three parts or mechanisms: (1) the receptor, (2) the control center, and (3) the effector. The receptor receives information that something in the environment is changing. What happens to the body after exercise homeostasis? To […]
What is the resistance across A and B in the Fig 1 point?
What is the resistance across A and B in the Fig 1 point? ⟹ RAB=4+44×4=2Ω What is the total resistance between points A and point B given below circuit? Therefore, the total resistance in the circuit is 4+4+2=10 ohms. What is resistance between A and B? The three resistance of 20 ohm, 10 ohm and […]
Why does a balloon move in different directions?
How do the kidneys respond to acidosis?
How do the kidneys respond to acidosis? The kidneys respond to acid-base disturbances by modulating both renal acid excretion and renal bicarbonate excretion. These processes are coordinated to return the extracellular fluid pH, and thus blood pH, to normal following a derangement. What can the kidney do to compensate for acidosis? Renal compensation of respiratory […]
Which way does current flow?
Which way does current flow? The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite […]
Can you go blind from astigmatism?
Can you go blind from astigmatism? Astigmatism is a problem of how the eye focuses light typically caused by a defect in the lens, resulting in distorted images. Astigmatism is not an eye disease or health problem. While it can cause blurred vision, eye strain, and headaches, particularly after prolonged reading, it does not cause […]
Is km a unit of speed?
Is km a unit of speed? The kilometre per hour (SI symbol: km/h; abbreviations: kph, kmph, km/hr) is a unit of speed, expressing the number of kilometres travelled in one hour. Which is not unit of speed? Answer. Explanation: b cannot be the unit of speed. How many Kilometre make an hour? 120km What’s the […]
What would happen if there was no hydrosphere on earth?
What would happen if there was no hydrosphere on earth? We know weather happens in the atmosphere, but without the hydrosphere, there would be no water to evaporate and so no cloud or rain could form. Without oceans and land (hydrosphere and geosphere), there would be no wind (as winds are produced by differences of […]
What two special image are formed by concave mirror?
What two special image are formed by concave mirror? Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as […]
