(from ohanian): a spaceship of frontal area 15 m2 moves through a large dust cloud with a speed of 2 x 106 m/s. the mass density of the dust is 7 x 10-18 kg/m3. if all the particles of dust that impact the spaceship stick to it, find the average decelerating force that the impacting particles exert on the ship. (you may assume that the mass of dust which sticks to the spacecraft is negligible compared to the mass of the spacecraft.)

Explanation:

Recognizing the data we have to,

So in this way we proceed first to decompose the variables,

The density is given by the formula

We also know that the Volume is given by

Where

Through this we relate volume to density

The momentum would be given as follows

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea

explanation:

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
