Question 1 In an optically thick source the observed flux is dependent on the projected area and the excitation temperature with a given velocity Vobs (Shaw et al., 2013). Consequently, optically thin sources are also dependent on projected area and excitation temperature, but their flux is calculated by obtaining an integration of the emissivity line over the volume. Therefore, in this case the observed flux will be given by fv=1-e-t2hv4 c31ehv/kTex-14πr2/d2 EQ 1 Where Tex represents the excitation temperature. In an optically thin source Tv << 1 J(k)T which is the emission coefficient can be given by hvk÷ehvkt-1Therefore, the middle equation in EQ 1 can be represented with Jv assuming...

Question 1 Triiodothyronine and Thyroxine, T3 and T4 respectively, are the hormones normally produced by the thyroid gland. Generally, these hormones increase the body metabolic rate which as a result leads to a rise in body temperature (Garcia-Reyero, 2017). In order to sustain this, more oxygen is required resulting in increased heart rate. The growth of muscles, bones, connective tissues and growth of the nervous system also requires thyroid hormone. Question 2 An overactive thyroid causes the metabolic rate to rise above normal. This causes a rise in body temperature, hence the sweating and increase in heart rate. Since her calorie intake doesn’t increase, it results in weight loss. The...

question is systematic risk 11.4 a. A change in the systematic risk as a result of high inflation announcement leads to the prices in the market falling. b. When Big Widget’s earnings fell within analysts’ expectations, then there is no change in unsystematic risk, which mean that price of Big Widget will probably remain constant. c. When government reports an expansion of the economy, prices in the bourse will probably remain spike. d. The sudden death of the company’s directors qualifies as unsystematic risk, which means that the prices of Big Widget will probably fall. e. The increase in corporate taxes is part systematic and unsystematic risks as it affects the calculation of...

Question 1. The current ratio for Potz and Pans has been calculated as 5.00:1 whereas the current ratio for WannaBees has been calculated as 1.76:1. Based on these results, it is prudent to assume that Potz and Pans is most likely to get the loan, although WannaBees also has good results. This is because the ratio is a measure of a company's capacity to meet its financial obligations. Both companies have current ratio figures greater than 1 to indicate that their assets are greater than the liabilities. Given that Potz and Pans has the highest ratio, it can be inferred that this is an indication that the company is financially well off. Still, the figures must be approached with caution since the...
