The vibrations created by noise can be converted to electrical energy through the principle of magnetic Induction, for example by using transducer.
Answer:
Option 4
Explanation:
During heating actually heat transfer takes place from a body at higher temperature to a body at lower temperature and the heat transfer takes place until both attain the same temperature
Therefore heat transfer depends on the temperature of the systems
Now while comparing the thermal energies of the systems, if both the systems have same mass then the system which is at higher temperature has greater thermal energy when compared to the system which is at lower temperature
So in this case assuming that both the systems have same mass then the energy will leave the system with greater thermal energy and go into the system with less thermal energy as the system with greater thermal energy in this case will be at higher temperature and we are considering this assumption because thermal energy not only depends on temperature but also depends on mass of the system
Answer:
I = 1.944 A
Explanation:
<u>Given the following data;</u>
Charge, Q = 3.5C
Time, t = 1.8 secs
Charge of a substance is given by the formula;
Where;
Q is the amount of charge measured in Colombs.
I is the current measured in Amperes.
t is the time measured in seconds.
Making I the subject of formula, we have
I = 1.944 A
Therefore, the current in the circuit is 1.944 Amperes.
