The problem is missing some parts but nevertheless here is
the answer:
Given:
1.7 m long barbell with 23 kg weight on the left and 34 in
the right end.
Solution:
Calculating from the left side:
Center of gravity = ΣM/ΣW = [23*0 + 9*(1.7/2) + 34*1.7]/[23+9+34]
Center of gravity = .992 m from the left end
Answer:
19
Explanation:
The mass of an atom is found in the nucleus: number of protons + number of neutrons; 9 + 10 = 19
The mass number of fluorine is 19
Conductors, type SIS, for switchboard wiring, have a maximum operating temperature of: 194 degree Fahrenheit.
<u>Explanation:</u>
A Panelboard or Switchboard wire is known as SIS.This type of SIS, have tin coating and it is manufactured with a copper conductor insulation. It is helpful for facilitating solder and also it will be easy to fix them in tighter spaces because for their flexible nature.
As they are insulated with XLPE they can be used at a voltage operating at 600 V and can be used at a temperature of 194 degree Fahrenheit or 90 degree Celsius. of The XLPE(Cross-Linked Polyethylene) insulation is rated for use at 90°C in either wet or dry locations at an operating voltage of 600 V. They can be used for distribution, panel and switch board wiring.
Answer:
The decrease in decibels is 0.1 dB.
Explanation:
Let the intensity of one chorus is Io.
let the intensity of 1000 vocalist is dB.
The intensity of 1000 vocalist is 1000 Io.
..... (1)
let the intensity of 999 vocalist is dB'.
..... (2)
So, the change is
= dB - dB' = 30 - 29.9 = 0.1 dB
