Answer:
Ep = 0.6095 [J]
Explanation:
As defined in the problem statement, potential energy is defined as the product of mass by gravity by height. But first we must convert all the values given to measures of the international system (SI)
g = gravity = 10 [m/s^2]
h = elevation = 40 [ft] = 12.19 [m]
m = mass = 5 [g] = 0.005 [kg]
Ep = potential energy [J]
Ep = 0.005*10*12.19 = 0.6095 [J]
There are many forces that make an object move.
· An Unbalanced force acting on an object
· Energy applied to an object.
Probability of both Lucy and Zaki hitting the target = 1/4
When Zaki or Lucy throw a ball at the target there are only two outcomes for each of them ( i.e Hit or miss )
Therefore :
The probability of Lucy hitting the target = 1/2
The probability of Zak hitting the target = 1/2
<h3>Analysis </h3>
Probability of both Lucy and Zaki hitting the target
P(Lucy ) + P(Zaki ) = 1/2 + 1/2 = 1/4
Hence we can conclude that Probability of both Lucy and Zaki hitting the target = 1/4

<u><em>Your question lacks some information but I have provided a general answer. </em></u>
Answer is: 124135 J.
m(water) = 55g.
T(water) = 100°C.
Q = ?
Q - heat needed to convert water to steam.
∆Hvap = 2257 J/g
∆Hvap - enthalpy of vaporization is the amount of energy <span> needed to transform the liquid substance into a gas.
Q = </span>∆Hvap · m(water) = 2257 J/g · 55g = 124135 J.
