2. What happen to the electrical signal as it reaches radio receiver? A. it generates low frequency electrical signal and low voltage.
B. It generates high frequency electrical signal and high voltage.
C. It generates low frequency electrical signal but high in voltage.
D. it generates high frequency electrical signal but low in voltage

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
