A certain part of a computer chip has a length of 1.5 micrometers. How many meters is this ?

1 answer:

4 0

When you're working with units of measure, "micro" almost always means "millionth", or 1 x 10⁻⁶ . And that's exactly the case in this example.

"1.5 micrometer" = 1.5 millionths of a meter, or 1.5 x 10⁻⁶ meter.

Answer:

488.6KN

Explanation:

Hello!

the first step to solve this problem we must find the pressure exerted at the bottom of the tank (P) which is the sum of the external air pressure (P1 = 92kPa), the pressure inside the tank (P2 = 100kPa) and the pressure due to the weight of the water (P3), taking into account the above we have the following equation

P=P1+P2+P3

to find the pressure at the bottom of the tank due to the weight of the water we use the following equation

$P3=\alpha gh$

where

α=density=1 g/cm^3=1000kg/M^3

H=height=14.1m

g=gravity=3.71m/s^2

solving

P3=(1000)(14.1)(3.71)=52311Pa=52.3kPa

P=P1+P2+P3

P=100kPa+92kPa+52.3kPa=244.3kPa

finally to solve the problem we remember that the pressure is the force exerted on the area

$P=\frac{F}{A} \\F=PA\\F=(244.3kPa)(2m^2)=488.6KN$

What does it mean when white light is diffracted and at a particular location the color seen is blue? Please use 2 content relat

Brilliant_brown [7]

When white light is diffracted and blue color is seen is due to the absorbance of wavelength of all other color except blue.

Explanation:

The white light diffracts into rainbow colors which are the 7 colors present in form of VIBGYOR.
VIBGYOR is the violet, Indigo, Blue, Green, Yellow, Orange and Red.
When the blue color is seen denotes the shortest wavelength being reflected and all other being absorbed at the specified location.
