Answer and Explanation:
The explanation is attached below
Answer: 5.36×10-3kg/h
Where 10-3 is 10 exponential 3 or 10 raised to the power of -3.
Explanation:using the formula
M =JAt = -DAt×Dc/Dx
Where D is change in the respective variables. Insulting the values we get,
=5.1 × 10-8 × 0.13 × 3600 × 2.9 × 0.31 / 4×10-3.
=5.36×10-3kg/h

notes from the speaker because notes are not visual aids. hope this helped :)
Answer:
The correct response is "$275,275".
Explanation:
The given values are:
Sales,
= 400,000
Gross margin,
= 120,000
Beginning Inventory goods,
= 150,475
Finished inventory goods,
= 145,750
Now,
The cost of goods sold will be:
=
On substituting the values, we get
=
=
As we know,
⇒

⇒ ($)
Answer:
The space station must turn at 0.24 rad/s to give the astronauts inside it apparent weights equal to their real weights at the earth’s surface.
Explanation:
In circular motion there’s always a radial acceleration that points toward the center of the circumference, so because the space station is spinning like a centrifuge it has a radial acceleration towards the center of the trajectory. To imitate the weight of the passengers on earth, they should turn the station in a way that the radial acceleration equals earth gravitational acceleration; this is:
And radial acceleration is also defined as:
with v the tangential velocity of the station and R the radius of the ring, solving for v:
We can find the angular velocity using the following equation:
That is the angular velocity the space station must turn.
