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
The basic unit of life is a cell. Have a great day!

The right option is Courtship
Courtship is a behavior in which different
species interact and select their partners for mating which leads to
reproduction. Most times, the female specie chooses the desired male to mate with before
copulation. Various behaviours such as display
of strength, dancing and vocal utterance are often used during courtship. For the question given above,<span>the type of behavior displayed by the species of balloon flies is an example of courtship.
