It’ll be 200 meters West because 500-300=200 and The west direction has the greatest force you could say ... Anytime you have a question asking about displacement you subtract then use the direction with the greatest number ..
These are the reactants because they are on the left side of the equation.
Answer: Oblique impact
Explanation:
When the motion of one or both of the particles is at an angle to the line of impact, the impact is said to be oblique impact.
On the other hand, when the directions of motion of the two colliding particles are moving along a line of impact, then it's refered to as central impact.
A mercury barometer is a device that is used to measure atmospheric pressure at a location. :)
Answer:
6 bricks
Explanation:
For the bricks system to NOT fall over, then the center of mass of the system must lie within the touching area of the bottom brick.
Let the reference line be at the left end of the base brick, and the bricks are being stacking to the right direction.
- The 1st brick would have a center of mass at 20/2 = 10 cm or 10 + 0, this is < 20 cm so it stays
- 2 stacked bricks would have a center of mass at (10 + 14)/2 = 12 cm or 10 + 2, this is also < 20 cm so it stays
- 3 stacked bricks would have a center of mass at (10 + 14 + 18) / 3 = 14 cm or 10 + 2*2, this is also < 20 cm so it stays
- 4 stacked bricks would have a center of mass at (10 + 14 + 18 + 22)/4 = 16 cm or 10 + 2*3, this is also < 20 cm so it stays
- 5 stacked bricks would have a center of mass at (10 + 14 + 18 + 22 + 26)/5 = 18 cm or 10 + 2*4, this is also < 20 cm so it stays
- 6 stacked bricks would have a center of mass at (10 + 14 + 18 + 22 + 26 + 28)/5 = 20 cm or 10 + 2*5, this is also <= 20 cm so it stays before tipping over.
- The 7th brick would make everything fall down.
