A satellite floats in deep space with very high velocity. It will continuously lose heat by Correct Answer Radiation

Explanation:

Heat transfer

The science that deals with the determination of the rate of such energy transfer due to temperature difference are known as heat transfer.

Mode of heat transfer:

  1. Conduction​
  2. Convection
  3. Radiation

Radiation

  • Radiation is the energy emitted by matter in the form of electromagnetic waves.
  • Unlike conduction and convection, heat transfer in radiation doesn’t require a medium.
  • The heat from the sun reaches the earth via a radiation mode of heat transfer.
  • A satellite floats in deep space with very high velocity. It will continuously lose heat by Radiation.
  • The governing equation for radiation is given by:

Q̇  = σAT4

where σ = Stefan-Boltzmann constant = 5.67 × 10-8 W/m2K4 ​

Read the following passage carefully and then choose the right word to complete the sentence that follows. Rockets are very expensive as it can be used only once. Appled scientists have therefore develped a reusable space craft called a space shuttle which takes off like a rocket; however, does no get destroyed as it returns to earth. It can also be used to lunch satellired into space, retrieve them from space if any repairing os required and allow around 8 scientists to crryout experiments in space. The space shuttle does not get.
A Carnot heat engine receives heat at 750 K and rejects the waste heat to the environment at 300 K. The net work output of the heat engine is used to drive a Carnot refrigerator, whose COP is 6.14.

The following sentences form a paragraph. The sentences are numbered as P, Q, R, S and T. These sentences are not given in their proper order. Read the sentences and choose the alternative that arranges them in the correct order. P- Anorexia is a very serious eating disorder and mental health condition which can be life-threatening if it is not recognised and treated in time, it has a huge negative impact on both the mind and the body. Q- ‘Anorexia nervosa is interchangeable with the term anorexia, which refers to self-starvation and lack of appetite’. R- Someone who suffers from anorexia struggles to maintain a healthy weight, because of the psychological impact it has on an individual they will experience the extreme need to continuously lose weight, S- they develop a very negative perception of self-image and can experience extreme anxiety at the fear of gaining weight. T- The most common age for anorexia to start developing is adolescent years, sadly for some who are anorexic, it becomes a way of life with no endpoint which has resulted in very young deaths as a result of starvation and the body shutting down.
