QUESTION 2 Which of the following is an accurate statement? O A. It is possible to add a scalar quantity to a vector. O B. Even though two vectors have unequal magnitudes, it is possible that their vector sum is zero. OC. Rotating a vector about an axis passing through the tip of the vector does not change the vector. OD. The magnitude of a vector is independent of the coordinate system used. O E. The magnitude of a vector can be zero even though one of its components is not zero.

According to the LA Times news report, a moderate magnitude 3.6 earthquake centered near the Granada Hills neighborhood occured on Jan 22, 2020. Use scientific notation in your final results to a) Refer to the Mercalli scale above to identify the intensity level, shaking and description/damage of the earthquake. b) Draw a cross sectional sketch of the earth identifying the FOCUS and epicenter of the earthquake. c) Determine the amount of energy released in ergs and d) Joules.

2. If the sun's output of solar radiation increased by 20%, how would this impact the temperature of Earth's mantle? Why?

What fraction of the iceberg lies below the water level?

8. The energy released đuring an earthquake can be calculated using the formula E(M) =(10'")“, where E is the energy in kWh (kilowatt hours) and M is the magnitude of the carthquake. a. The magnitude 9.5 earthquake in Southern Chile on May 22, 1960 is thought to be the strongest earthquake that has ever occurred. Use the formula above to caleulate the energy released during this earthquake. Express the answer in scientific notation, to the nearest tenth. b. An earthquake of magnitude 3 may not be felt or noticed by most people. Calculate the energy, to the nearest tenth, that is released during an earthquake of this strength. ( c. Compared to a magnitude 3 carthquake, how many times greater was the energy that was released during the 1960 earthquake in Chile? d. An earthquake that occurred in Central Canada in 2010 released approximately 30 000 000 kWh energy. Find the magnitude, to the nearest whole number, associated with this carthquake.
