How simple machines achieve mechanical advantage?

to what circuit element is an ideal inductor equivalent for circuits with constant currents and voltages?

You come across an open container which is filled with two liquids. Since the two liquids have different density there is a distinct separation between them. Water fills the lower portion of the container to a depth of 0.

What are two things that characterize a biome

Pluto orbits the Sun at an average distance of 5.91 * 10^12 meters. Pluto's diameter is 2.30 * 10^6 meters and its mass is 1.31 * 10^22 kilograms. Charon orbits Pluto with their centers separated by a distance of 1.96 * 10^7 meters.

Can you think of any common ""real-life"" situations in which an understanding of conservation would allow a concrete operational child to react differently than a preoperational child? Provide several examples in the space below.

Nikolas, the fire extinguisher, and the skateboard have a combined mass of 50 kg. What force would the fire extinguisher have to produce to propel Nikolas if he wanted to accelerate at a rate of 1.

A set of data is collected from a simple circuit with a 20 resistor and is represented in the table

A skydiver of mass m jumps from a hot air balloon and falls a distance d before reaching a terminal velocity of magnitude v. Assume that the magnitude of the acceleration due to gravity is g. a.

8. What happens to force when mass is increased?

Give an example of ionic and covalent bond, and explain and make an example for each.
