A wire has a length of 5.93 × 10-2 m and is used to make a circular coil of one turn. There is a current of 5.44 A in the wire. In the presence of a 5.43-T magnetic field, what is the maximum torque that this coil can experience? Number i Units

Scientists are conducting an experiment to determine if their hypothesis that a certain constant in the universe is 1.65. the uncertainties in the experiment result in a relative uncertainty of no more than 2%. After several experimental trials, the scientists obtained an average value of 1.7 for the constant. What can be said about the scientists hypothesis? Hint calculate the percent error and compare it to the relative uncertainty.

Use the Widmark Equation, , to solve this question. Recall that r = 0.68 for men and r = 0.55 for women. B = percentage of BACN = number of “standard drinks” (A standard drink is one -ounce beer, one -ounce glass of wine, or one -ounce shot of liquor.) N should be at least one.W = weight in poundsr = the distribution rate for alcohol through the body (this value is a constant),  for males and  for femalest = number of hours since the first drink     A male student had four glasses of wine at a party. He weighs 172 pounds. How long will it take before his BAC falls to 0.05​​​​​​​? 3.14 hours 3.57 hours 1.00 hours 4.29 hours

The elliptical galaxy NGC 4889 is the largest galaxy in the Coma Cluster (shown in the image below taken by the Hubble Space Telescope). After analysing the spectrum of NGC 4889, an astronomer identifies a spectral line as being CaII (singly ionised Calcium) with a measured wavelength of 401.8 nm. The true, rest wavelength of this spectral line, measured in a lab, is 393.3 nm.  Using a Hubble constant of ?0 = 70 km/s/Mpc, find the distance to this galaxy cluster. Give your answer in megaparsecs and in light-years.
