ps what kind of person would drink water after you put salt in it lol.
Answer:
1) The car is slowing down
2) A = 40N forward & B = 25N up
Explanation:
Whenever you're dealing with forces on moving objects, it is important to look at each of the numbers and the directions they're going in.
With the racecar, we see it has four forces on it, 2,000 N up and down, 8,000 back, and 6,000 N forward. Now, each of these forces are going in their respective directions, but they are most in comparison with the force going in the opposite direction (vertical axis, horizontal axis). The two 2,000 N forces will cancel each other out since there is an equal force in both directions, causing a net force of <u>0 N on the vertical axis</u>. This is because the car is most likely moving on a flat surface. As for the horizontal axis, we simply subtract 6,000 & 8,000 to get a net force of <u>-2,000 N in the backwards direction</u>, telling us that the car is slowing down.
As for the boxes, we see the same vertical and horizontal axes, but separated to each box. Box A has a net force of <u>40 N in the forward direction</u> and Box B has a net force of <u>25 N in the upward direction</u>.
Answer:
333.5 MJ
Explanation:
ΔV = m·g·Δh
= 8500 · 9.81 · (15000-11000)
= 8500 · 9.81 · 4000
= 333 540 000
≈ 333.5 ·10⁶J = 333.5 MJ
Using the appropriate arithmetic operation, the amount of potatoes and cabbage require for the voyage are 19998 and 26664 respectively.
- <em>Number</em><em> </em><em>of</em><em> </em><em>men</em><em> </em><em>=</em><em> </em><em>47</em>
- <em>Number</em><em> </em><em>of</em><em> </em><em>women</em><em> </em><em>=</em><em> </em><em>32</em>
- <em>Number</em><em> </em><em>of</em><em> </em><em>children</em><em> </em><em>=</em><em> </em><em>22</em><em> </em>
- <em>Number</em><em> </em><em>of</em><em> </em><em>voyage</em><em> </em><em>days</em><em> </em>
Total number of passengers = (47 + 32 + 22) = 101
1.)
If each person gets 3 potatoes per day :
Number of potatoes needed per day = (3×101) = 303
Number of potatoes needed for entire voyage = (303 × 66) = 19998 potatoes.
2.)
If each person gets 4 cabbage per day :
Number of cabbage needed per day = (4×101) = 404
Number of cabbage needed for entire voyage = (404 × 66) = 26664 cabbages.
Hence, the number of cabbage needed for the voyage would be 26664 cabbages.

Planetary Nebula is a shell of glowing ionized gas surrounding a dying star.
Explanation:
Planetary Nebula is a shell of glowing ionized gas surrounding a dying star.
It shows the that star is dying or or is reaching its final stage of life. This term is associated with red giant stars. They are at the verge of dying and glow which is the ionized gas.
