Please answer all the question, I will definitely give thumb up Thank you

Question 5 (2 points) The expression "black holes are fussy eaters" refers to the fact that O material forms an accretion disk rather than falling straight into the black hole black holes do not swallow much of the matter supplied to them O black holes are unable to swallow dark matter O radiation pressure creates jets that squirt out the rotational axis of the black hole Save Question 6 (2 points) We can infer so much about the properties of the jets in the source SS 433 because O we know the magnetic field topology in the accretion disk around the black hole O we can constrain its distance very well and hence we know its luminosity ( the donor star has a well-known age and spectral type, which allows us to determine the accretion rate onto the black hole O the source exhibits redshifted and blueshifted emission lines that vary periodically

Explanation / Answer

5] option b is corrected. Black holes do not swallow much of the food given to eat. Although many theories oppose this, but it is the meaning of the given statement.

6] option d is correct.

We measure the sources redshift and blueshifted emission lines periodically and also look at the emission spectra we get off the jet in many wavelengths including optical and radio.

7] optio d is correct. All of the above
