If a tectonic plate moved 234 km in 23.7 my, what was the speed of this plate motion?9.87 km/my55.45 km/my9.357 km/my19.873 km/hr9.123 km/my The Correct Answer and Explanation is : To find the speed of the tectonic plate motion, we can use the formula for speed, which is: [\text{Speed} = \frac{\text{Distance}}{\text{Time}}] Given: First, we calculate

How to increase Plant Plant Utilization in Capsim Capstone in rounds? A closed cycle consists on an expansion at constant pressure, then a heat loss constant volume and finally at isentropic compression. The working fluid is air. Initial pressure and initial specific volume are 1000K Pa and 0.1 m/kg respectively and the final volume is
