Could I please have some help with these?
A11)
Ephoton = Ebind + Ekin
hc/delta = Ebind + 0.5mv^2/
I subbed in values provided and rearranged to find velocity.. It
gave me a negative value.
(Ebind = 206000 J, h= 6.6261x10^-34, c= 2.99x10^8, delta = 215 x
10^9m)
A19) & A33) How would I go about these?
Thank you

Check my work John Fleming, chief administrator for Valley View Hospital, is concerned about the costs for tests in the hospital's lab. Charges for lab tests are consistently higher at Valley View than at other hospitals and have resulted in many complaints. Also, because of strict regulations on amounts reimbursed for lab tests, payments received from insurance companies and governmental units have not been high enough to cover lab costs. Mr. Fleming has...
please answer these and please make it clear for my
understanding
