Consider the retaining walls in Figures la and lb.
(i) The retaining wall in Figure la is unyielding (i.e. the wall does not translate or rotate) and
there are no lateral strains in the ground. Draw the Mohr Circle that represents the stress
state of Soil A. Be sure to label your plot and include the Mohr-Coulomb failure envelop.
(ii) The retaining wall in Figure Ib moves away from the backfill. Based on Rankine's earth
pressure theory, derive the coefficient of earth pressure for Soil A. Draw the Mohr Circle
for this new stress state of Soil A on the same plot from (i),

- The number density of air in a child's balloon is roughly the same as sea level air, 1019 particles/cm3. If the balloon is now 26 cm in diameter, to what diameter (in km) would it need to expand to make the gas inside have the same number density as the ISM, about 1 particle/cm3?

- Bushfires in Australia have been worsening for more than two decades as escalating drought places pressure on forest resilience and recovery. Bushfires are likely to occur across Australia through at least March 2022 and are a typical feature of the summer and early fall in the country, particularly after long dry spells or during spans of extremely high temperatures. One time, there’s a bushfire occurred in Southeast Australia and the local government will put the fire out before it burns more land. They send an airplane used to drop water on brushfires and is flying horizontally in a straight line at 475 mi/h at an altitude of 630 ft. Determine the distance d at which the pilot should release the water so that it will hit the fire at B.arrow_forwardHow does the greenhouse effect work? Is it beneficial or harmful to humans?arrow_forwardHow many hours of sunlight does it take to capture the same amount of energy stored in 1 L of petrol, if instead of using a tree we use a solar panel?Assume: a tree takes up around 30 m2 of land area; we have a solar panel with the same area as that taken up by the tree; 1 L of petrol contains 34.2 MJ of energy; a solar panel captures energy at an average rate of 50 W/m2 for 12 hours a day. How many hours does it take to capture the required amount of energy? Give your answer to one significant figure.arrow_forward
- The recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be? B) Assuming your change in energy is negative (hint-it should be), where does your body get the extra energy to maintain it's temperature?arrow_forwardWhat percentage of the total radiation absorbed by the earth’s surface comes directly from the atmosphere and clouds?

- Question 5. Assume the amount of sunlight falling on the land where the owl pellets were collected is: 6 kilowatt hours/ m² / day, which is the equivalent of 4500 kcal / m² / day.

Assume efficiencies of 40 % for power plants. The current CO2 level in the atmosphere is 370 ppm by volume. Assume that all of the atmosphere's mass is within 11 km of the planetary surface. Is this a reasonable value? If it is not, state some reasons. State all your assumptions. NOTE: PLEASE DO NOT ANSWER IF YOU ARE GOING TO SOLVE PARTIALLY!!!arrow_forward
