5. The magnification of a telescope is the effective focal length (efl) of the telelscope optics divided by the focal length of the eyepiece, and the results should be unitless (ie
magnification does not have things like mm or inches in it). Calculate the magnification
of the following systems. Show your work. (note eyepieces are interchangeable, so
astronomers generally don't care about the magnification - if it doesn't look good, we just
change the eyepiece.)
a. efl: 80 inches, eyepiece: 40 mm
|
b. efl: 80 inches; eyepiece 25 mm
c. efl: 325 cm; eyepiece 35 mm

Models are non-visual ways of coummincating how someone thinks about something in the natural world

Nhumans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? in humans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? a, b, ab, and o ab and o a, b, and o a and b

Diabetes is often suspected when glucose shows up in urine tests. use the model to explain how glucose could be present in urine. why do you think this symptom is especially concerning for young people?
