GenaCL600 [577]

Answer:

\rho=1.8\times 10^{-8}\Omega.m

Explanation:

Given:

width of the wire, w=1.8\ mm=1.8\times 10^{-3}\ m

thickness of the flat wire, d=0.12\ mm=1.2\times 10^{-4}

length of the wire, l=12\ m

voltage across the wire, V=12\ V

current through the wire, I=12\ A

Now the net resistance of the wire:

using ohm's law

R=\frac{V}{I}

R=\frac{12}{12}

R=1\ \Omega

We have the relation between the resistivity and the resistance as:

R=\rho.\frac{l}{a}

where:

a = cross sectional area of the wire

\rho = resistivity of the wire material

1=\rho\times \frac{12}{1.8\times 10^{-3}\times 1.2\times 10^{-4}}

\rho=1.8\times 10^{-8}\Omega.m

Answer:

Good morning! It's D. all of the above

Explanation:

Social backgrounds, culture, politics, education and economic reasoning might equally contribute to uncontrolled settlements. People live in disaster-prone areas partly for economic reasons. In the case of Semarang, where tidal flooding submerges houses, people stay due to economic factors.

What is the concentration of H+ ions at a pH = 2? mol/L What is the concentration of OH– ions at a pH = 2? mol/L What is the rat
densk [106]

Answer:

In Step 5, you will calculate H+/OH– ratios for more extreme pH solutions. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide for a solution at a pH = 2. Then divide the H+ concentration by the OH– concentration. Record these concentrations and ratio in Table C.

What is the concentration of H+ ions at a pH = 2?

0.01   mol/L  

What is the concentration of OH– ions at a pH = 2?

0.000000000001   mol/L  

What is the ratio of H+ ions to OH– ions at a pH = 2?

10,000,000,000 : 1

I LITERALLY spent 40 MINUTES trying to figure out this question, so please, use my VERY CORRECT answers!

I hope this helps!

What occurs when water droplets in the atmosphere become heavier than the air surrounding them can hold?
Anon25 [30]
The water droplets then became precipitation, and depending on the climate/weather, it could turn into rain, snow, sleet, or even hail.

A light wave travels through air in equals 1.00 at an angle of 35 degrees what angle does it have when it passes from the air in
lyudmila [28]

Answer: Angle 59 degree

Explanation: Given that the

n1 = 1.0

n2 = 1.5

Øi = 35 degree

From Snell law, which says that

n1/n2 = sinØ1/ sinØ2

Substitute all the parameters into the formula

1/1.5 = sin 35/sinØ2

Cross multiply

Sin Ø2 = 1.5 sin35

SinØ2 = 1.5 × 0.573 = 0.860

Ø2 = sin^-1(0.860)

Ø2 = 59.36 degree

Ø2 = 59 degree ( approximately)

It has angle 59 degree when passing from air to glass
