Academics

Q1. The average rate at which energy is conducted outward throughout the ground surface in a certain region is 54.6 mW/m2, and an average thermal conductivity of the near-surface rocks is 3.49 W/m•K. Assume a surface temperature of 3.75°C, find the temperature (in Celsius) at a depth of 35.0 km (near the base of the crust). Ignore the heat generated by the presence of radioactive elements.

Q2. An 8,000 rocket is shot straight up from the Earth's surface with the initial speed of 800 m/s. How high does it go?
