Answer:
Mass of 17.854 kg is only attached to the spring
Explanation:
We have given time period in first case is 22 sec
Let initially mass is m
After 22 kg are added the period becomes 33 sec
Time period of spring mass system is
, here m is mass and k is spring constant
From the relation we can see that


Squaring both side


m = 17.584 kg
So mass of 17.854 kg is only attached to the spring
Answer: D. Tantalum pentoxide
Explanation:
It has the highest dielectric constant at 26
The given question is incomplete. The complete question is as follows.
Two identical balls each have a mass of 35.0 grams and a charge of q = 3.50 \times 10^{-6}C[/tex]. The balls are released from rest when they are separated by a distance of 6.00 cm. What is the speed of each ball when the distance between them has tripled? Use k =
.
Explanation:
According to the conservation of energy, the formula will be as follows.

or, ![\frac{kq_{1}q_{2}}{r_{1}}[1 - \frac{1}{3}] = mv^{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bkq_%7B1%7Dq_%7B2%7D%7D%7Br_%7B1%7D%7D%5B1%20-%20%5Cfrac%7B1%7D%7B3%7D%5D%20%3D%20mv%5E%7B2%7D)
Putting the given values into the above formula as follows.
![\frac{kq_{1}q_{2}}{r_{1}}[1 - \frac{1}{3}] = mv^{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bkq_%7B1%7Dq_%7B2%7D%7D%7Br_%7B1%7D%7D%5B1%20-%20%5Cfrac%7B1%7D%7B3%7D%5D%20%3D%20mv%5E%7B2%7D)
= 23.333
v = 4.83 m/s
Thus, we can conclude that speed of each ball when the distance between them has tripled is 4.83 m/s.
