Which of the following radioisotopes is used as anticancerous? (a) Na -24 (b) C -14 (c) U -235 (d) Co -60

Which of the following radioisotopes is used as anticancerous?

(a) Na -24

(b) C -14

(c) U -235

(d) Co -60

Expert Solution

Answer : (d) Co -60

Explanation :

Co-60 is used as anti-cancerous among the given radioactive isotopes. It emits β− particles and energetic gamma rays, for which reason it is used in radiation therapy. Cobalt 60 (60Co) is often the ideal mode of radiation for treating laryngeal cancer. For primary treatment of laryngeal cancer, 60Co allows adequate dosing of the superficial tissues.

d) Co-60

Use the following to answer questions 11-14: Suppose that firms A, B, C and D are Bertrand duopolists in the salt industry. The market demand curve can be specified as Q=100-3p, Q=qA+qB+qC+qD. (The firms choose prices simultaneously.) The cost to firm A is C(qA)=7qA. The cost to firm B is C(qB)=3qB. The cost to firm C is C(qC)=7qC The cost to firm C is C(qD)=3qD Firm A will earn? (piA=?)

a) U = xy b) U = (xy)^1/3 c) U = min(x,y/2) d) U = 2x + 3y e) U = x^2 y^2 + xy 4. All functions except c) are differentiable. Do these functions exhibit diminishing marginal utility? Are their Marshallian demands downward sloping? What can you infer about the necessity of diminishing marginal utility for downward- sloping demands?
