Only the smartest person in science can help me right now...Look at the screenshot! 1. Use the given soil triangle. What percentage of sand does loam have?

2. Use the given soil triangle. What percentage of silt does loam have?

3. Use the given soil triangle. Look for the letter B in Sandy Clay Loam. What percentage of clay does "B" have?

4. Use the given soil triangle. Look for the letter B in Sandy Clay Loam. What percentage of silt does "B" have?

Current enters a circuit at a: 1.positive terminal 2.negative terminal 3.low potential side 4.resistor

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
