-- The total distance between the towns = 460 km.

-- For the first 3 hours, he travels at an average speed of 60 km/hr.  During that time, he covers (60 km/hr) x (3 hrs) = 180 km.

-- At that point, he still has (460km - 180km) = 280 km to go.

-- If he drives that 280km at an average speed of 70 km/hr, it'll take him (280km)/(70km/hr) = 4 hrs to cover it.

-- His total time for the whole trip is (3 hours for the first part) + (4 hours for the last part) = <em>7 hours</em>.

A charge Q is uniformly spread over one surface of a very large nonconducting square elastic sheet having sides of length d. At
Umnica [9.8K]

Answer:

Explanation:

Given

Charge Q is uniformly spread over large non-conducting Elastic sheet      

Electric field due to non-conducting Elastic sheet

E=\frac{\sigma }{2\epsilon }

where \sigma =surface charge density=\frac{q}{d^2}

E=\frac{\frac{q}{d^2}}{2\epsilon }

for side 2d Electric Field is given by

E'=\frac{\frac{q}{2d^2}}{2\epsilon }

E'=\frac{1}{4}\times \frac{\frac{q}{d^2}}{2\epsilon }

E'=\frac{E}{4}

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
