Why is there no drag in space?????? Help me please!!! Thanks!!!

astraxan [27]

It is beacuse of fluid If there is no fluid, there is no drag. Drag is generated by the difference in velocity between the solid object and the fluid. If this statement is correct then how can there be drag in space if there is no air?

As a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk. It so happens th

MA_775_DIABLO [31]

Answer:

Watermelon is going at a speed of $13.33\ \rm m/s$ in downward direction

Explanation:

Given

Height of the Empire State building = 320 m
Speed of the superman = 24 m/s

since both the motion of both watermelon and the superman is under gravity. The acceleration of both is g in downwards direction. So the relative acceleration between them is zero and when they meet the relative distance covered by them will be the height of the Empire State building.

so let t be the time when they meet given by

$\dfrac{320}{24}\\t=13.33\ \rm s$

Now let v be the velocity of the the watermelon when they meet given by

$v=gt\\v=9.8\times13.33\\v=130.63\ \rm m/s$

An electric motor is traversed by 3.10²º electrons in 6 seconds. Determine the intensity of the current passing through the moto

Effectus [21]

Current is the amount of charged passed divided by elapsed time.

I = Q/Δt

I = current, Q = charge, Δt = elapsed time

We also know an electron has a charge of 1.6×10⁻¹⁹C, so let us find the total charge by multiplying this unit of charge by the total number of electrons:

Q = 1.6×10⁻¹⁹(3×10²⁰) = 48C

We also have Δt = 6s, so let's plug these values in to solve for I:

I = 48/6

I = 8A
