The drag force acting on the rocket is 80N.
<h3>Give an explanation of drag force?</h3>
The divergence in velocity between the fluid and the item, also known as drag, exerts a force on it. Between the liquid and the solid object, there should be motion. Drag is absent in the absence of motion.
The air molecules are more compressed (pushed together) on the surfaces that are facing the front while being more dispersed (spread out) on the surfaces facing the back. Turbulent flow, which occurs when air layers split from the surface and start to swirl, is what causes this.
The drag force acting on the rocket F = ma
Given,
m = 4kg, a = 20ftm/s²
Substituting m and a values in the above formula,
The drag force acting on the rocket F = 4×20
The drag force acting on the rocket F = 80N.

You can describe the location of any event ... past, present, or future... with
four numbers, representing the four dimensions of the universe we live in.
The numbers are the three space coordinates of the event ... the 'x', 'y', and 'z'
of its physical location ... and the 't' of its location in time.
They eat rice, chicken, beef, cereal they eat what we eat in a daily basis I guess
This is true. they have numbers on the side that help to determine the volume.
This so that astronauts can study the chemical atmosphere of a planet better. We will know whether the atmosphere will be toxic to our lungs or not. Astronauts need to have a deeper understanding of a planet before going there. For example, before going to the Moon, humans relatively understood what the Moon had no atmosphere, so if you walked in there like you walk down here on Earth, you'd die to shortness of breath. We understood that before landing because these different telescopes help us put light rays not within the visible light spectrum into visible light in images. Hope this helps ;)
