Answer:
Explanation:
a ) Current remains the same throughout the whole of a closed circuit if all the resistances are in series. So current will remain the same in both these conductors as they are in series.
b ) If the two wires are switched or exchanged mutually , there will not be any change in the current are they will still remain in series and total resistance remains the same . so current will remain the same . Hence the current through the bulb will remain unchanged . The brightness too will remain the same.

Answer:
for question no.4,
time =6 secs
acceleration due to gravity (g)= 9.8 m/s^2
velocity=gt
=6×9.8
=58.8m ans...
for question no .5,
time taken = 4seconds
aacceleration due to gravity (g)=9.8 m/s^2
distance=12gt
=12×9.8×4
=470.4meter answer...
Answer:
In some fields of physics, they are distinguished by their origin: Gamma rays are created by nuclear decay, while in the case of X-rays, the origin is outside the nucleus.
Explanation:
It is true that as the frequency of sound waves increases, the wavelength of the sound waves decreases.
