You lift a 45-n bag of mulch 1.2 m and carry it a distance of 10 m to the garden. how much work was done?

Abeam of light shining from water to air strikes the surface at an angle greater than 48 degrees and produces total internal reflection. if the incident beam is at a 50 degree angle what angle is the reflected beam 13 25 50 100

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)

The temperature of a solution can change the solubility of a substance. the chart shows the solubility of the same solute at different temperatures in water. based on the chart, which solution was at the optimal temperature to allow for the greatest solubility? w x y z
