We preserve the important events and people in our lives. The ceremonies of birth and birthdays, marriages and anniversaries, holidays and new houses are all recorded because they matter. Photographs are our personal story, a timeline of our lives filled with faces and places that we love.

B

Explanation:

Because if we will mental it... Think The ball a is thrown upward even it can pull downward by the gravity ball b is the fastest because the ball b has already force to hit the ground and when the gravity pull it the force that has the ball b much be faster than its original force

Sorry, if you dont understand ask

me I'm glad to help you thanks

Explanation:

Given the formula for Potential Energy, PE = mgh,

*where PE = 22.5 J, g = 9.8 m/s^2 & h = 10 m

We will just substitute the given (& hidden) values to the formula in order to find out the mass of the fruit.

Since we are solving for mass, then we will use the formula: m = PE/gh

m = PE / gh

m = (22.5 J) / (9.8 m/s^2)(10 m)

m = 22.5 J / (980 m^2/s^2)

m = 22,050 kg
