Estimate how long a COVID-19 infected droplet will remain in the air when exhaled. Treat the droplet as a sphere of water with a 5 µm radius. Use the size and density of water to determine the mass of the sphere. Find the terminal velocity of the droplet and, using a reasonable height, approximate the time the droplet will remain in the air.

In this problem you are going to use your knowledge of drag forces to estimate how long a COVID-19 infected droplet will remain in the air when exhaled. Treat the droplet as a sphere of water with a 5 μm radius. Use the size and density of water to determine the mass of the sphere. Find the terminal velocity of the droplet and, using a reasonable height, approximate the time the droplet will remain in the air.
Find the minimum sample size n needed to estimate μ for the given values of c, σ, and E. c=0.90, σ=8.9, and E=2 Assume that a preliminary sample has at least 30 members. n=enter your response here (Round up to the nearest whole number.)
The mean flee path for helium at a certain temperature and pressure is 2.10107 m. The radius of a helium atom can be taken as 1.101011 m. What is the measure of the density of helium under those conditions (a) in molecules per cubic meter and (b) in moles per cubic meter? `

Why is the oxygen tank in the experiment equipped with a regulator and a relief valve? What are these instruments for? Is it possible to fill the bomb with oxygen without them? What effect would their absence have on the bomb filling system?
As of August 27, 2020, the Philippines, through the Department of Finance has already borrowed $ 8.83 billion to fight against the health and socioeconomic crises inflicted by the COVD19 pandemic. (a) If payments were made at the rate of $1000 per second, how many many years would it take to pay off the debt, assuming no interest was charged? A one-dollar bill is about 15.5 cm long. If $8.83 billion one-dollar were laid end to end around the Earth's equator, how many times would they encircle the planet? Take the radium of the Earth at the equator to be 6378 km.

Using the systematics of exponential processes, the time scale for getting out of a pandemic at its peak through exponential decay of the infection rate or the death rate is estimated from: If the delta variant death rate per day (Po) peaked at 2000 in late September and declined at the national rate of − 1% per day, what is t, the time in days to defeat the virus (i.e. time until the last person dies)? answer choices: 350 525 450 760
