There are two forces acting on a rocket at the moment of lift off: Thrust pushes the rocket upwards by pushing gases downwards in the opposite direction.Weight is the force due to gravity pulling the rocket downwards towards the centre of the earth.So I'm thinking the answer is THRUST.
The length of the inclined plane is approximately 12 ft
The situation forms a right angle triangle.
<h3>Right triangle</h3>
Right triangle have one of its angle as 90 degrees.
Therefore,
The length of the inclined plane is the hypotenuse of the triangle. The length of the inclined plane can be found using trigonometric ratios.
height = 4 ft
angle(∅) = 19.45°
sin 19.45 = 4 / h
h = 4 / 0.33298412235
h = 12.0125847796
h = 12 ft
Therefore, the length of the inclined plane is approximately 12 ft

Explanation:
Let us assume that the question says,"In a shower connected in summer and winter positions, with the following characteristics: 220V - 2200W / 4400W. Calculate the electric current that circulates at the lowest (summer) and highest (winter) power, with the same voltage. Tip: isolate the electric current in the expression P = Ix V
"
It is given that,
In a shower connected in summer and winter positions, with the following characteristics: 220 V - 2200 W / 4400 W.
It means lowest power is 2200 W and highest power is 4400 W
For lowest power,
I = electric current for summer
For highest power,
I' = electric current for winters
