for the parame variable does it represent? [10 marks] Question 3 (9 marks) It is known that the sun, and many other stars undergo some mode of dscillation. a. How does the frequency of oscillation,, depends on the density of the star,p, its radius, R and the gravitational constant, G? Given the dimensions of the variables are: [w] = T-1, [p] = ML-3, [R] = L, [G] = M-iL3 T'2 [5 marks] b. Verify your model using the fact that the sun's density is 1400kgm-3, the gravitational constant is 6.67408 x 10-1l m3 kg s-2 and the period of oscillation is approximately 1 hour. [2 marks] c. Predict the frequency of oscillation for the neutron star with density 7 x 10likgm-3 [2 marks] Page 2 of 3 J Labadin
