a) 0.321 ly
b) 0.321 light years is not far in astronomical terms. Alien life would need to transmit at tremendous power in order for their radio transmissions to be detectable. Their radio signal also needs to be stronger than background noise in order to be distinguishable. Therefore it is unlikely that radio transmissions from alien life will ever be detected.
By adding up all the individual forces of the object
As frequency decreases , the wavelength will increase !!
frequency= speed of light ÷ wavelength
( inverse relationship )
Answer:
space , small amount of gravity is found in the space ,infact we can say that there is no gravity in the space
