Answer:
d = 3.56 x 10⁻⁴ m = 0.356 mm
Explanation:
The diameter of the aperture can be found using the following formula:
where,
y = distance between dark rings = 1.65 mm = 1.65 x 10⁻³ m
λ = wavelength = 490 nm = 4.9 x 10⁻⁷ m
L = distance between screen and aperture = 1.2 m
d = diameter of aperture = ?
Therefore,
<u>d = 3.56 x 10⁻⁴ m = 0.356 mm</u>
The disadvantages of shared decision making are:
Adopting a wrong advice from a member can lead to a big risk to the company and the business.
Further, increased number of advice also confuses the person, about which to follow and which to ignore.
There is also diffusion of responsibility and lowered efficiency.
Answer:
the answer would be strongest because just took this question
Explanation:
The voltage in the extension cord is 30 V.
The problem above can be solved using ohm's law
⇒ Formula:
V = IR.................. Equation 1
⇒ Where:
- V = Voltage in the extension cord
- I = Current flowing through the extension cord
- R = Resistance of the extension cord.
From the question, I think there was a slight error in the value of the current given it suppose to be 500 A, and not 5.00 A
⇒ Given:
⇒ Substitute these values into equation 1
Hence the voltage in the extension cord is 30 V
