A bob of mass m = 0.200 kg is suspended from a fixed point with a massless string of length L = 25.0 cm . You will investigate the motion in which the string traces a conical surface with half-angle θ = 24.0 ∘. What tangential speed v must the bob have so that it moves in a horizontal circle with the string making an angle 21°C with the vertical?

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
