In the distant future, a new planet has been discovered around a nearby Sun-like star. The following information is known about this planet: 1) It has
a density of 4.1 compared to water; ii) its orbital semi-major axis is 1.7 AU;
iii) it has a very thin CO2 atmosphere; iv) imaging of the surface shows an
extensive amount of cratering as well as no liquid water on the surface.
There is evidence of volcanic activity in the distant past. Determine the
following based on the above information:
a) What type of planet is this? (Terrestrial or Jovian)

A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.

Utah's great salt lake has an average salinity seven times higher than that of the oceans. very few multicellular organisms live in this harsh environment. an example is the brine shrimp, which must devote a large portion of its metabolic energy to osmoregulation. these brine shrimp must available hint(s)utah's great salt lake has an average salinity seven times higher than that of the oceans. very few multicellular organisms live in this harsh environment. an example is the brine shrimp, which must devote a large portion of its metabolic energy to osmoregulation. these brine shrimp must pump water back into their cells to counter its loss due to osmosisactively pump water back out of their cells to counter its inflow due to osmosissynthesize membranes that are impermeable to substances that upset osmotic balanceactively pump salt back out of their cells to counter its inflow due to osmosis
