Answer:
• riding on a Ferris wheel whose entrance and exit are the same
• walking around the block, starting from and ending at the same house
• running exactly one lap around a racetrack
Explanation:
Displacement simply means the.change in position of an object. In a situation whereby the initial and final position are thesame, the displacement will be zero.
The statements that describe a situation with a displacement of zero include:
• riding on a Ferris wheel whose entrance and exit are the same
• walking around the block, starting from and ending at the same house
• running exactly one lap around a racetrack
You are sitting at the center of a large turntable at an amusement park as it is set spinning freely. You decide to crawl towards the edge of the turntable. Rotational speed will decrease
There is no external torque
hence , the angular momentum of the table is conserved
L (initial) = L ( final)
since , L = m*v*r
where
m = mass
v = velocity
r = radius
If the person is crawled towards the outer rim, then the rotational inertia of the turntable will increase. In order to conserve the angular momentum , its rotational speed will decrease as mass and radius cannot be altered .

The following enumeration is the list of actions which are
considered to be illegal when operating your boat:
1
Operating
the boat in a harsh or inconsiderate manner
2
Operating
the boat in the absence of safety equipment
3
Actual
weight exceeds the carrying capacity of the boat
4
Not
prohibiting the riders to sit on gunwales,
transom, stern, sides, bow or decking over the bow sides when the boat is
underway, except when sufficient guards or railings are provided
5
Operating
the boat or giving permission to other people to operate the boat while drunk
or under illegal substances
6
Operating
the boat and the wash or wake endanger any property or person
7
Operating
the boat in an area designated for swimming
8
Operating
the boat beyond a slow, no wake
speed in locations marked as no wake zones
We can see that in this case, the rule # 6 is being trespassed.
Therefore under Minnesota Boating Laws, we have committed an Illegal Operating
Practice.
yes
Explanation:
because if a car is 100 pounds then it will have less force than a 250 pound car
