Answer:
Explanation:
The centripetal acceleration requirement must equal gravity at the top of the circle
mg = mv²/R
v = √Rg
v = √(1.0(9.8))
v = 3.1304951...
v = 3.1 m/s
Answer:
Amazing Thanks. What about u?
Explanation:
Answer:
O pH is a measure of the concentration of H+ ions in a solution of an acid or base. The pH plots
the concentration of solutions in a range from 0-14.
Explanation:
pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral.
Answer:
Explanation:
First of all, we analyze the system of blocks before starting to move.
Hence, the incline angle θ for which both blocks begin to slide is 10.20°.
Now, if we do a free body diagram of block A we have that after the block moves, the spring force must be taken into account.

Where:



Therefore, the required stretch or compression in the connecting spring is 0.10 ft.
I hope it helps you!
