Explanation:
Answer: Annealing
Explanation:
In the manufacturing of glass, Processes such as expansion when glass heats and cooling when it contracts are involved. These build up random internal stresses which can cause cracks and breakage when finally cooled at room temperature. To relieve these stresses, Annealing is carried out on glass during the manufacturing process.
Annealing is the process whereby the temperature during the process of the manufacturing of glass is reduced and maintained at a uniform rate so that it undergoes a gradual cooling process. so as to make the glass tough and reduce internal stress.
Answer:
120 Hz
Explanation:
Given that a 60 Hz sinusoidal voltage is applied to the input of a half-wave rectifier, what will be the output frequency ?
Ideally, the supply frequency will be equal to the ripple frequency.
But in a half - way rectifier, the out put frequency is twice the input sinusoidal voltage frequency.
The output frequency = 2 × 60
Output frequency = 120 Hz
Therefore, When a 60 Hz sinusoidal voltage is applied to the input of a half-wave rectifier, the output frequency is 120 Hz.
