Answer:
B. 5.9 X 10^9
Explanation:
For this question, we assume the following:
•2.3 x 1014 inches is actually 2.3 x 10^14 inches.
•3.9 x 104inches is actually 3.9 x 10^4inches
We now calculate thus;
The average distance in km would be 2.3 x 10^14/3.9 x 10^4
= 0.59 X 10^10.
Therefore, we have;
5.9 X 10^9km.
one of the property of radio waves is that they have long wavelength. due to their long wavelength , they undergo diffraction around the mountains and thus the waves spread around the mountain. this makes them eligible to be used for long distance communication. they can coded and decoded also . that is why they are used in television and radio system
Answer:
30 m/s
Explanation:
Vf = ?
Vi = 0 m/s
a = 20 m/s^2
t = 1.5 s
Plug those values into the equation: Vf = Vi + at
Vf = 0 + (20)(1.5)
Vf = 30 m/s
Birth happens very quickly, so it is hard to "catch" stars in the act. - most stars are born inside dusty clouds, which block any light that may be coming from the stars.
