Power is the RATE of use, flow, or transfer of energy.
1 watt = 1 joule PER SECOND.
The correct choice is ' <em>a</em> '.
the equation of the line allows us to find the answer is
y = -27.8 t + 97.4
The equation of a line in a linear relationship between two variables, its general expression is
y = A x + B
in this case the slope is the quantity that the independent variable in this case A = -27.8 m / s
The cut-off point that is the value of the dependent variable for x = is b = 97.4 m
In this case we see that the slope has a unit of [m / s] and the dependent variable is a unit of length, therefore the independent variable must have a unit of time [s] so that the entire equation is in units of length
y = -27.8 t + 97.4
[m] = [m / s] [s] + [m]
[m] = [m]
The other two magnitudes with are necessary to write the equation r is the mean square root and gives an idea that the values also fit the line, the best value is 1
In conclusion, the equation of the line allows us to find the answer is
y = -27.8 t + 97.4

Im think its A. A release of a large amount 9f energy
Answer:
(c) at point 2, the ball is at its highest height do its PE is max. Also at ms height, velocity is zero therefore KE is zero.
Answer:
The maximum height reached by the water is 117.55 m.
Explanation:
Given;
initial velocity of the water, u = 48 m/s
at maximum height the final velocity will be zero, v = 0
the water is going upwards, i.e in the negative direction of gravity, g = -9.8 m/s².
The maximum height reached by the water is calculated as follows;
v² = u² + 2gh
where;
h is the maximum height reached by the water
0 = u² + 2gh
0 = (48)² + ( 2 x -9.8 x h)
0 = 2304 - 19.6h
19.6h = 2304
h = 2304 / 19.6
h = 117.55 m
Therefore, the maximum height reached by the water is 117.55 m.
