How can you predict the time of next perihelion passage of a newly observedcomet?

A halo CME is estimated to be traveling at 800 km/s.  Assuming it is Earth-directed, estimate the time required to reach Earth.  Express your answer in hours to 2 significant digits. The transit time is  ______ hr.

Assume that the bolt can be represented as a long, straight line of current. At a perpendicular distance of 29 m from the bolt, a magnetic field of 8.2 x 10=5 T is measured. How much charged has flowed during the lightning bolt? 3. > 7:18 PM O Type here to search 后 3/17/2021 !!! II 近 9

A new astronomical measurement suggests that the Hubble constant is 51 kilometers per second per Megaparsec. If this measurement is correct, what would the Hubble time be in units of years? Is this a plausible value based on other astronomical evidence? Why or why not?

Alec O MEASUREMENT Distinguishing accuracy and precision Four research teams measured the length of a rare whale, and what each team wrote in its team notebook is shown in the table below. Suppose a later and more reliable measurement gives 78 m for the length of the same whale. Decide which of the earlier measurements was the most accurate, and which was the most precise. what was written most accurate most precise team in the notebook measurement measurement A "98.m" B "between 83.m and 93.m" C "83.m + 10.0m" D "58.m + 3.0%" Explanation Check O 2020 McGraw-Hill Education, All Rights Reserved.

If the cosmic microwave background radiation (CMBR) is the remnant of the Big Bang’s fireball, we expect to see hot and coldregions in it. What are two causes of these wrinkles in the CMBR? Are the observed temperature variations greater or less thanoriginally expected?
