Answer:
20.85 years
Explanation:
2.61 km = 2610 m
2.07 kW = 2070 W
First we need to calculate the potential energy required to take m = kg of rain cloud to an altitude of 2610 m is
With a P = 2070 W power pump, this can be done within a time frame of
or 658037739/(60*60) = 182788 hours or 182788 / 24 = 7616 days or 7616 / 365.25 = 20.85 years

Answer:
The football must be launched whit an angle of 20,487 degrees to reach a maximum height of 10 meters.
Explanation:
To solve this problem we use the parabolic motion equations:
We define:
: total initial speed =
:initial speed component in vertical direction (y)
=
: vertical speed at any point on the parabolic path
g= acceleration of gravity= 9,8
= angle that forms the total initial velocity with the ground
Equation of the speed of the football in the vertical direction :
Equation (1)
We replace, in the equation (1):
Equation(2)
Angle calculation
The speed of the football in the vertical direction gradually decreases until its value is zero when it reaches the maximum height.
We replace , in the equation (2)
°
Answer:The football must be launched whit an angle of 20,487 degrees to reach a maximum height of 10 meters.
As with all wave interactions, you just add the wave's amplitudes together. Resonance occurs when the two waves which meet are of the same frequency, so they add together constructively, making it much larger than either of the independent waves.
