<span>A. Natural selection
Able to find more food means more likely to survive - survival of the fittest i.e. natural selection.</span>
The answer is Club fungi. I hope this helps!
The formulas that will be used are:
Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.
Gravitational force = GMm /r²
Centripetal force = mv²/r
Equating,
GMm/r² = mv²/r
v² = GM/r
The first scenario will use the formula v² = GM/r
Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.
v = 2rπ/t
<span><span>What is the distance covered by a vehicle
moving in a straight line during 20 s if the vehicle changes its speed from 10
m/s to 16 m/s during that time interval? In order to calculate the distance of
the boat we first have to identify the suited formula for acceleration in this
scenario. </span>
<span>Hence, a = vf – vi / t. Vi = 10 m/s Vf = 16 m/s T
= 20 seconds </span>
<span>Solution: </span>
distance = velocity x time</span>
Distance = 16 + 10 m/s / 2 x 20 seconds
Distance = 260 meters
