A 0.094 kg meter stick is supported at its 40 cm mark by a string attached to the ceiling. A 0.62 kg object hangs vertically from the 6.77 cm mark. A second mass is attached at another mark to keep it horizontal and in rotational and translational equillibrium. The acceleration of gravity is 9.8 m/s^2. If the tension in the string attached to the ceiling is 20.1 N, find the value of the second mass.

In order to experience earth like gravity (one G) on its inter- surface, what would the rotational period of a cylinder with a diameter of 10 miles (17 kilometers) be? The cylinder is 25 miles long (40 kilometers) and is rotating in space outside the influence of other gravatational influences. The cylindar has a mass of 18,247,680,000 metric tons. Would you notice coriolis forces while walking in such a cylindar?

T or F determine if the word with ** makes the phrase true or false. if false what's true?

1. If movement is constant,it is *possible* to determine whether you or another object is moving.

2. There is only *1* frame of reference.

3. Speed that does not change is called *constant speed*

4. When you write the velocity of a hurricane you need to write the *direction*

5.Velocities that have the same direction combine by *subtraction*

6. A rocket going to the moon is an example of *deceleration*

7. In circulat motion the velocity is *continuosly changing*

8. *all* moving objects have momentum.

9. A bullet has a large momentum because of it's *velocity*

10. A total momentum before and after a collision is *unchanged*.

11. A *distance time graph* is shown with a curve.


thanks so much for the help
sorry i know it's a lot of questions

its said that in the large hadron collider- CERN when experiment starts later this year miniblack holes will be produced.

If im not wrong there miniblack holes wont last for long and will evaporate due to Hawking radiation.

Can you please explain why the creation of these miniblack holes are important in the collider? what role do they play?
