I figured it out: Pic for reference Based on what you have learned about the units for measuring thermal energy, complete the following passage The unit often used in chemistry and physics to measure energy, such as for work or electrical current is the ✓ joule We can also use this unit, as we did in this lab, for measuring specific heat This is a property that is quantified by the energy needed per ✓ gram of material to raise the temperature by one ✓ degree Celsius The unit for this measure is therefore ✓ degree Celsius

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

Which car has the most kinetic energy? a. a car of mass 1000 kg with a speed of 3 m/s b. a car of mass 2000 kg with speed 7 m/s c. a car of mass 1000 kg with speed 7 m/s d. a car of mass 2000 kg with speed 3 m/s

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?
