It takes the moon about 27 days to revolve on its axis.
Answer: 1479watts
Explanation:
Power is defined as the energy expended or work done in a specific time.
Mathematically,
Power = Workdone/time taken
Since work done is force × distance
Power = force × distance/time
Force = Mary's weight = 87N
Distance = height of the flight = 102meters
Time = 6.0seconds
Substituting in the formula we have;
Power = 87 × 102/6
Power = 1,479watts
Note that the time must be in seconds before usage. If its given in minutes, you will have to convert to seconds
Potential energy is energy stored due to its position. Thermal energy is energy released as heat

The ones with pH greater than 7
Explanation:
A pH scale is a scale for expressing the level of acidity or alkalinity of aqueous solutions.
This scale is called a pH or pOH scale. The pH is the common one.
pH of a solution is the negative logarithm to base 10 o the hydrogen ion concentration of the solution.
- The scale ranges from 1 through 14.
- An acidic solution has a pH value less than 7. Neutral solutions have pH of 7 and basic solutions have pH greater than 7.
