The SARS-CoV-2 (COVID-19) virus can be described as approximately spherical having a diameterof about 120 nm. If the density is about the same as water, 1 000 kg/m*, determine the mass ofone COVID-19 virus. Express your answer in picograms. Clearly show your calculations and unitconversions using the chain method.

Density is defined as mass per unit volume,. Here the diameter of the virus is given, using which…

dV An oil tanker aground on a reef is forming a circular oil slick about 0.1 foot thick. To estimate the rate (in cubic feet per minute) at which the oil is leaking from the tanker, it was found that the radius of the slick was increasing at 0.31 foot dt dR dV per minute (- = 0.31) when the radius R was 400 feet. Find using T 3.14. dt dt Tanker A=TR? V=0.1A R dV ft3 /min dt (Type an integer or a decimal. Round to the nearest whole number as needed.)
