Bo learns about the law of inertia. it states that objects at rest tend to stay at rest, and objects in motion tend to stay in motion the state of motion changes only when another force acts on an object. bo wants to use this law to predict how a soccer ball will roll on the grass after he kicks it. which statement best describes the motion of the ball(answer choices in picture)

Why do electron microscopes have higher resolving power than light microscopes?

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.

Simple machines can a. increase force only b. decrease force only c. increase or decrease force
