Hello dear readers, welcome back to another Solve it Sunday riddle. I hope you are enjoying these puzzle-solving posts. I don’t think they attract a lot of attention, but I like trying to figure out the puzzles as I write them
I wish you luck in solving this one and, as always, the answers are in the comments!
Several statements are given below. You may assume – for the duration of this problem – that they are absolutely truein all particulars. From that assumption, you should be able to provide an answer to the question that follows.
No one goes to a party without brushing his or her hair.
Untidy people are never fascinating.
Alcoholics have no self-control.
People with brushed hair look fascinating.
No one wears white gloves, unless he or she is going to a party.
A person is always untidy if he or she has no self-control.
A pendulum is a very simple machine, but a highly interesting one none the less. A pair of identical pendulums suspended in a vacuum jar will, naturally enough, move in perfect synchrony once set swinging. If you lengthen the string of one of the pair, it will slow down, falling behind the other. Similarly if you instead shortened the string, it would speed up.
What would happen if you kept the strings the same length, and instead replaced one of the weights with a similarly sized bob made of substantially lighter material?
Best of luck in solving this! Sometimes trusting your gut helps.
This puzzle may require a certain amount of thought.
Imagine that you have a pair of perfectly elastic balls, one very much larger and heaver than the other. You place the lighter ball on top of the heavier one, and then drop them a distance of 1ft onto a perfectly rigid floor.
How high will the lighter ball bounce?
It may help to bear in mind that kinetic energy is: (mass x (speed x speed)) / 2.
It is likely that you have walked around a cold house barefoot at some time or another in your life. If so, you will probably have noticed that under such conditions, carpeted floors feel warmer to walk on than tile.
It should be clear that this is the case even when there is absolutely no difference between the actual temperatures of the various stretches of flooring. So why do we perceive a difference?
Try sitting straight on a chair, with your back and lower legs vertical, and your thighs horizontal. You will discoed that if you neither move your feet nor bend your torso forward, it is impossible to stand up.
Feel free to try it. You will be unable to stand until you either move your feet back, or your chest forward.
