Answer:
Since Alice has a greater density it will also have a greater mass
Density = mass / volume
The potential energy at the surface of Alice will be greater and a higher kinetic energy will be required to escape the planet's gravitational pull.
PE = K M / R potential at surface is greater because mass is greater
KE = 1/2 M v^2 greater velocity required to overcome PE
This could be a problem because then the gardener can't control where they want the plants to grow because the seeds can go anywhere from the different ways the plants distributes them.
The answer to the question that is being presented above would be musical instruments. These instruments are used to create sounds of different pitches and tones by musicians. They operate through being striked or 'sawed' to create vibrations that produce sound.
Power is calculated by dividing energy with time (J/s) or Watts
In this case, The energy is given by mgh where mg is the weight and h is the vertical height.
Thus, Energy = 600 × 4 = 2400 Joules
Power = Energy /time
Time will therefore be Energy/power
= 2400 J/ 200
= 12 seconds
