6,000 Joules. The formula for KE is KE=1/2mv^2. 20^2= 400. 400 x 30=12,000. 12,000/2=6,000. :)
Yes this true because Someone moves forward for 5 seconds and moves back for 5 seconds
Which 5+5=10
so you would have in ten seconds
Answer:
The average surface temperature decreases the further you get from the Sun because the more distant planets receive less energy/heat/sunlight per square meter of their surface. This is because the energy from the Sun spreads out (becomes less concentrated) as you travel further from the source/Sun.
Explanation:
Answer:
B
Explanation:
Heat flows from hot to cold to lower the temperature of hot areas and increase temperature of cold areas. The end result is that the 2 areas have the same temperature, thus increasing entropy.
Its fake some of its real like the space part and the traveling through space part but not the multi dimensional stuff
