State Kepler’s Law and Write the three laws given by Kepler. How did they help Newton to arrive at the inverse square law of gravity? |
|
Answer» Three laws given by Kepler are as follows:FIRST LAW: The orbits of the planets are in the shape of ellipse, having the Sun at one focus.SECOND LAW: The area swept over per hour by the radius joining the Sun and the planet is the same in all parts of the planet's orbit.THIRD LAW: The squares of the periodic times of the planets are proportional to the cubes of their mean distances from the Sun.Newton used Kepler's third law of planetary motion to arrive at the inverse- SQUARE rule. He found that the orbits of the planets around the sun are circular, and not elliptical, and so derived the inverse - square rule for gravitational force using the formula for centripetal force. This is given as:F= m/r → (1), where m is mass of the particle, r is the radius of the circular path of the particle and v is the VELOCITY of the particle. Newton used this formula to determine the force acting on a planet REVOLVING around the sun. Since the mass m of a planet is constant equation (1) can be WRITTEN as :F∝ → (2)Now, if the planet takes time T to complete one revolution around the sun, then its velocity v is given as:v = 2r/T → (3), where r is the radius of the circular orbit of the planet.or, v∝ r/T → (4)On squaring both sides of the equation, we get: ∝/ → (5)On multiplying and dividing the right hand side of the relation by r, we get:a1/r → (6)According to Kepler's third law of planetary motion, the factor / is a constant. Hence equation (6) becomes:∝ 1/r → (7)On using equation (7) in equation (2) we getF∝1/Hence, the gravitational force between the sun and a planet is inversely proportional to the square of the distance between them.Explanation:Hope this will help you .rate me brainliest please. |

your younger sister has severe diareoha write four other symptoms which can confirm that she has cholera what is the incubation period of the disease what three points would you keep in mind while taking care of her |
|
Answer» Symptoms of CholeraThe majority of people exposed to cholera never become ill. In fact, in most cases, you may never know you’ve been exposed. Once you’re infected, you’ll continue to shed cholera bacteria in your stools for seven to 14 DAYS. Cholera usually causes mild to moderate diarrhea, like other illnesses.One in 10 people who are infected will develop typical symptoms within two to three days after infection.Common symptoms of cholera include:SUDDEN onset of diarrheanauseavomitingmild to severe dehydrationThe dehydration caused by cholera is usually severe and can cause tiredness, moodiness, sunken eyes, dry mouth, shriveled skin, extreme thirst, reduced urine output, irregular heartbeat, and low blood pressure.Dehydration may LEAD to loss of minerals in your blood. This can lead to an electrolyte imbalance. The first SIGN of an electrolyte imbalance is severe muscle cramps. An electrolyte imbalance can eventually lead to shock.Children usually have the same cholera symptoms as adults. Children may also experience the following:severe drowsinessfeverconvulsionscomaCholera rarely occurs in first world nations. If you follow proper food safety practices, even in affected areas, the risk of infection is minor. Still, cholera continues to occur worldwide. If you develop severe diarrhea after visiting an area with a HIGH rate of cholera, you should see a doctor.Explanation:꧁♛YOU CAN TAKE ANSWERS AS PER YOUR CAPACITY♛꧂꧁♛HOPE IT HELPS♛꧂꧁♛PLEASE MARK IT AS THE BRAINLIEST♛꧂ |

how did the desired for the freedom of his people change Nelson Mandela life ?in about 100to 150words |
|
Answer» y, Mandela enjoyed MANY of freedom. He was not RESTRICTED to go ANYWHERE. He used to run freely in the fields and to swim in the stream in his village. For him, freedom at this time was restricted to the freedom of his own. As a student, he wanted freedom only for himself. He wanted the freedom to STUDY, stay away at the night and to have the freedom to go anywhere. When he GREW up freedom for him became a very important thing to be talked upon. The definition of courage for Mandela was to win and attain victory over fear. For him, the absence of fear was not the meaning of being courageous. He considered men to be brave when they had the courage to conquer fear. He does not want a condition in the society where the men would be fearless.Plzzzz mark it as brainliest if it helps. ☺ |

Answer» Most of the current ash transport and dispersion models neglect particle-fluid (two-way) and particle-fluid plus particle-particle (four-way) reciprocal interactions during particle fallout from volcanic plumes. These interactions, a function of particle concentration in the plume, could PLAY an important role, explaining, for EXAMPLE, discrepancies between observed and modelled ash deposits. Aiming at a more accurate prediction of volcanic ash dispersal and sedimentation, the settling of ash particles at particle volume fractions (ϕp) ranging 10−7-10−3 was performed in laboratory experiments and reproduced by numerical simulations that take into account first the two-way and then the four-way coupling. Results show that the velocity of particles settling together can exceed the velocity of particles settling individually by up to 4 times for ϕp ~ 10−3. Comparisons between experimental and simulation results REVEAL that, during the sedimentation process, the settling velocity is largely enhanced by particle-fluid interactions but partly hindered by particle-particle interactions with increasing ϕp. Combining the experimental and numerical results, we provide an empirical model allowing correction of the settling velocity of particles of any size, density, and shape, as a function of ϕp. These corrections will impact volcanic plume modelling results as well as remote sensing retrieval techniques for plume parameters. Volcanic ash is injected in the atmosphere during explosive eruptions and, dispersed by wind and eventually deposited on the ground, may cause health, social, and economic disruption during and after an eruption1. Where, when, and how ash from an eruption may impact human activities is currently forecast by using numerical simulations of ash dispersal. Current simulations incorporate wind advection, atmospheric DIFFUSION, particle aggregation, and simplified sedimentation models that consider the terminal velocity of particles as if settling individually2,3. To overcome this last simplification, here we describe joint experimental and numerical simulations investigating the effect of particle volume fraction on the settling velocity of volcanic ash particles in suspensions. Complexities of the volcanic cloud-atmosphere system and large variations in the size, density, shape and concentration of erupted particles result in large variations in ash settling dynamics and corresponding settling velocity. The terminal settling velocity of a single volcanic ash particle is usually derived analytically and/or experimentally, and previous STUDIES focussed primarily on the effect of particle size, shape, and density, and of atmospheric properties on this parameter4,5,6,7,8,9,10,11,12. This approach considers the settling of an individual particle in a still fluid, ignoring the presence of neighbouring particles. Similarly, the effect of particle volume fraction (ϕp) on the settling velocity of individual (i.e., not aggregated) particles is not included in most numerical models of ash dispersal13,14,15,16,17,18,19,20 which are mostly concerned with the fate of volcanic ash in the dilute, medium-distal regions of the plume. These models assume particles are only affected by the drag due to the local velocity of the carrier flow (one-way coupling), ignoring the effect of particle motion on the flow itself (two-way coupling) and inter-particle collisions (four-way coupling). This approach is justified as long as ϕp is less than 10–6, below which negligible alteration to the structure of turbulence by particles occurs21,22. With increasing ϕp in the fluid, however, two-way and four-way coupling effects are expected to play an increasingly important role on the settling velocity of particles23,24,25,26,27,28. Within a few hundreds of kilometres from the vent, ϕp in the plume can be as high as 10−5, and up to 10−3 in more proximal regions29,30,31. The observations and modelling of localized regions of instability, including particle-rich ‘fingers’ or ‘scalloped umbrella’32,33, suggest that the dynamics of particle sedimentation is strongly governed by several factors mostly related to particle concentration34. |
