Thermoforming process involves injecting of molten plastic into a mould cavity by application of compressed air. Correct Answer False

In thermoforming process, a sheet of plastic is used which covers the shape of any die by heating it to the desired temperature and then it is stretched over the die using vacuum, thus it is also called as vacuum forming. Then the pressure is applied to the plastic sheet by using pressurized air.

Given that the wave number of a circular cavity resonator is 151 (TE011 mode), and the length of the cavity is twice the radius of the cavity, the radius of the circular cavity operating at 5GHz frequency is:
Read the paragraph and answer the question that follows: Incessant combustion of fossil fuels emits toxic gases, polluting the air; urbanization results in deforestation and hence poor air quality; littering of plastic waste damages the productivity of soil and pollutes water bodies. Environmental pollution results in more serious consequences like – global warming, unexpected climatic changes, depletion of natural resources, species depletion, and various other adverse effects leading to a lowered sustainability of life on earth. Another prime contributor to the pollution of the environment is plastic pollution. Plastic bags those are not disposed of properly, reach the soil and water bodies, polluting them and damaging dependent lives. Being non-bio degradable plastic lingers around for years, rendering them useless. What is the prime contributor to pollution?

When a pattern is to be withdrawn from the mould, it is first shaken, by striking over it from side to side, so that its surface may be free of the adjoining sand wall of the mould. That causes the size of the mould cavity increases a little and a negative allowance is to be provided in the pattern to compensate the same, is known as:
At the mould exit of a continuous caster, the metal consisting of a solidified shell with a liquid metal core exits at the rate of 35 kg S-1. Given that the latent heat of fusion is 3 × 105 J kg-1 and the total rate of heat removal by the mould is 4.2 × 106 W, the mass fraction of solid at the mould exit is . . . . . . . .
