Answer: b)All substances emit radiation
Explanation: This is a universal statement that all bodies emit radiations . The radiations are usually in the form of electromagnetic radiations that are being emitted in accordance with temperature that varies from body to body.Even human bodies along with any other body emit radiations These radiations are absorbed by the black body.Therefore the correct option is option(b).
Answer:
Explanation:
A multipurpose transformer can act as step up as well as step down transformer according to the desired setting by a user.
When the voltage at the output is greater than the voltage at the input of the transformer then it acts as step-up transformer and vice-versa acting is a step down transformer.
Given that:
input (primary) voltage of the transformer,
no. of turns in the primary coil,
- When the output voltage is 5.60 V:
turns compensating the losses
- When the output voltage is 12.0 V:
turns compensating the losses
- When the output voltage is 480 V:
turns compensating the losses
