Cause earth orbits around the sun in a year and we have 24 hours in a day
Kinetic energy = 0.5*M*V^2
Q7-
0.5*3*(2^2)= 6J
Q8a-
0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J
the second ball has more kinetic energy.
Q8b-
at the max height, all the kinetic energy is converted to potential energy,
gravitational potential energy is = M*g*h
that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:
First ball:
2kg*9.81(g)*10m = 196.2J
Second ball
4kg*9.81*10m= 392.4J
The second ball has more potential energy
You can't really expect to find water stored as a gas, as it cools to a liquid at room temperature. You could easily find evaporated water on a stovetop by boiling water, though.
This is a question that you would have to answer
for example: i found a small and colorless bear looking animal(sight). When i touched it was fuzzy and soft(touch). It smelled like dirt and lavender(smell). The creature was sleeping and it was breathing slowly(hearing). I took one of its hair’s and it was like human hair(taste)
BUT REMEMBER since it’s a species it could be an animal or human or a plant.
hopefully I could help!!
