C. Both because the It physical change is caused by a medical one
The system of two rods will lie on the table as show in the figure
The center of first rod will lie exactly at the edge of first rod and then the center of mass of two combined rods will lie at the edge of the table.
So now the whole system will rest on the rod and it will not tipping off.
Since both rods are identical so we can say that the system will have its center of mass at the mid point on the line joining the two centers
So the value of x will be at mid point of line joining the two points on rod
So total length over the edge will be given as
Answer:
The Internet (social media to be precise)
Explanation:
False science are purported scientific conclusions drawn without any scientific data or procedures followed to arrive at such conclusions. These purported conclusions would have been irrelevant or not widespread without the internet or social media but the easy accessibility to social media globally has made "everyone" to be a scientist or even a publisher without scientific steps.
Some innocent individuals also help share (on the internet) these false science because of the inability to differentiate between the real scientific process and the ones done without any/some due scientific processes hence assisting in promoting these false science unknowingly. If there were no internet, these false sciences would not be this widespread as information will not travel this fast.
Set it up as a direct proportion:
2.0lb/9hb = x/100hb
solve x (100hb •2.0lb)/9hb = 22.2lb
22.2lbs
The answer is Kevin's weight may change between Planet X and Planet Y.
<u>Explanation</u>:
- The mass is the amount of matter contained in our body and it does not vary with other planets (remains constant). But the weight on the planet is the strength of gravity on the planet and result of mass which will vary with different planets. Your weight is a measure of the pull of gravity between the person and the planet.
- Every object in the universe will attract each other object with the same mass. When the gravity is high, your weight will be high because your weight will be depending on the gravitational pull of planets.
- For example, if an astronaut travels from Earth to Mars, his mass remains unchanged and he floats with the same size and mass but his weight will vary due to varying gravity. Thus your mass doesn't affect other planets it's only the weight that may change due to the varying gravitational pull or no gravity.
