Power = (energy) / (time)
= (60 joules) / (4 seconds)
= 15 joules/second
= 15 watts

Answer : The speed of waves along the wire is, 1.2 m/s
Explanation :
Formula used :
where,
= frequency = 
= wavelength = 
c = speed of wave = ?
Now put all the given value in the above formula, we get the speed of waves along the wire.
Thus, the speed of waves along the wire is, 1.2 m/s
Answer:
actually quantity of matter present in a body is its mass.
Answer:
C. All planets orbit the Sun in the same direction.
E. The orbits of the planets are evenly distributed in distance from the Sun.
F. All planets orbit the Sun in a roughly flat plane.
Explanation:
As we can see that due to big bang theory of planet formation we can say all planets revolve around the sun in circular orbit with almost in same plane
Size of the planets are unevenly distributed and they all revolve around the sun in same directions
so here correct options are
C. All planets orbit the Sun in the same direction.
E. The orbits of the planets are evenly distributed in distance from the Sun.
F. All planets orbit the Sun in a roughly flat plane.
