Answer:
Im pretty sure that it applys
KE=1/2mv^2
So the 3kg ball rolling at velocity of 3m/s has a KE=1/2(3)(3^2)=27/2=13.5J
The 2kg ball only has a KE=1/2(2)(3^2)=9J
So we can see the 3kg ball has more KE than the 2kg ball because they are moving at the same velocity so the bigger mass has more KE
Solar energy is one of the renewable energy sources that is invested around the world because of its large potential. the sun as a free source can sometimes bring a drawback. one of the drawbacks is that it cannot be harnessed when storms or rains are present in the weather. it is also expensive and young.
Answer:
Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm
Explanation:
Given ;
Average speed = 3.5cm/year
Time= 1 s
Distance = speed × time
Number of seconds in a year = 31536000 sec/year
Distance = 3.5 cm/year × 1/31536000sec/year × 1 s
Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm
