Textbook Question
Chapter 28, Problem 104TE
Chances are about 50-50 that in any night sky there is at least one visible comet that has not been discovered. This keeps amateur astronomers busy looking night after night, because the discoverer of a comet gets the honor of having it named for him or her. With this high probability of comets in the sky, why aren't more of them found?

There is one part to this question. I need to know the days. Thank you!
The Tunguska asteroid is estimated to have had a diameter of 50 m, and to have produced an explosion equivalent to 10 megatons of TNT (1 megaton = 4.2 x 1015 joules). Assume that the asteroid was a sphere with density 2 g/cm3. Using the kinetic energy formula K = ½ mv2, where m is the mass and v is the speed, to estimate the speed of the asteroid. Assume that all kinetic energy is converted into the energy of the explosion.
Give your answer in km/s with one significant figure.
Give me the solution for the problem.
The correct answers are:
A: -1.4 x 10-6 km/h. The comet's speed has been decreased by this amount. Hence, the effect is negligble.
B: -6.7 x 10-8 km/h. The Earth's speed has been decreased by this amount. Also, the effect is negligble.

- ____ daysarrow_forwardA lot of asteroid and comet dust collides with Earth's atmosphere everyday. Assume that 500 tons of mass is added to Earth daily from the millions of meteors that enter our atmosphere. Estimate the time it would take for the Earth's mass to increase 0.2% with this impact rate. Is this mass accumulation significant to Earth as a planet.arrow_forwardWhich of the following is least reasonable regarding comets? Group of answer choices Short-period comets originate in the Kuiper belt and take less than than about 200 years to orbit the Sun. Long-period comets originate in the Oort cloud and can take millions of years to orbit around the Sun, in randomly oriented orbital planes. The ion tail of a comet tends to produce a blue glow, as the ions inside it absorb sunlight and re-emit the absorbed energy with a characteristic color (somewhat like the gas atoms in a neon light or in an Aurora). An ion tail is typically narrow and straight and always trails the comet, like long hair in the wind. The dust tail of a comet often looks curved and its whitish color is just reflected sunlight.arrow_forward

Figure 20 shows jets emerging from the comet. Do these images confirm that comets are ‘dirty snowballs’? Why, or why not?arrow_forwardThis is a challenging problem. Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values. Note: If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check your calculations! This problem is closely related to the spectacular impact of the comet Shoemaker-Levy with Jupiter in July 1994. (More information about the event can be found here.) A rock far outside a solar system similar to ours is initially moving very slowly relative to its sun, in the plane of the orbit of a large planet (about the size of Jupiter) around its sun. The rock falls toward the sun, but on its way to the sun it collides with the planet. The mass of the planet is 4 x 1027 kg, the mass of its sun is 3.2 x 1030 kg, the radius of the planet is 1.4 x 10® m, and the center-to-center distance from the planet to the sun is 9.2 x 1011 m.
