Answer:

About 3.06 seconds

Explanation:

v_f=v_o+at

Since at the peak of its trajectory, the ball will have no velocity, you can write the following equation:

0=30+(-9.81)t\\\\-30=-9.81t\\\\t\approx 3.06s

Hope this helps!

Let's say you have two tuning forks which are supposed to produce the same frequency, 512 Hz. One is of good quality, but the ot
solong [7]

Answer:

= 2 beats per seconds

Explanation:

  • From |f -f'| = modulus of the difference between the frequency given.
  • f = 510Hz and f' = 512Hz
  • Difference between the frequency will give us the number of beat per seconds.
  • i.e 2 beats per seconds

These also shows how to get the period of the tuning forks.

If a neutral metal comb is held near an object with a negative charge, the Como become charged by
LenKa [72]
The local charging of the comb is due to induction. The negative object's charge pushes electrons in the comb away from the side close to the charged object causing that part to be positively charged. Note that the comb's net charge is still zero provided it doesn't touch the object. When you move the comb away its electrons will redistribute.

What will happen if you put a usb drive and a magnet too closely together?
kakasveta [241]
<span>If you put a magnet right next to a USB drive, depending on the strength of the magnet and the amount of steel, nickel or cobalt used in the construction of that particular model of USB drive, the drive would either adhere to, or not adhere to, the magnet. This would cause no other significant effects. The storage of data in solid state form (as in USB drives) is not magnetic in nature, so no deletion or any other damage of the stored data would occur.</span>
