The ceiling in your new bedroom is slanted. Still, you want to attach a wooden shelf to it. In your plan, the 70.0 cm, uniform, 50.0 N shelf is supported horizontally by two vertical wires attached to the sloping ceiling A shelf is supported horizontally by two vertical wires attached to the inclined ceiling. The left wire is 25.0 centimeters long and it is attached to the left edge of the shelf. The right wire is 75.0 centimeters long and it is attached to a point on the shelf 20.0 centimeters to the left of its right edge. A tool is placed on the shelf midway between the points where the wires are attached to it. Installing the shelf, you forget a very small 20.0 N tool midway between the points where the wires are attached to it.

Which term best describes the phrase “something that happens”?

Chapter 23, problem 075 the figure shows a geiger counter, a device used to detect ionizing radiation (radiation that causes ionization of atoms). the counter consists of a thin, positively charged central wire surrounded by a concentric, circular, conducting cylindrical shell with an equal negative charge. thus, a strong radial electric field is set up inside the shell. the shell contains a low-pressure inert gas. a particle of radiation entering the device through the shell wall ionizes a few of the gas atoms. the resulting free electrons (e) are drawn to the positive wire. however, the electric field is so intense that, between collisions with gas atoms, the free electrons gain energy sufficient to ionize these atoms also. more free electrons are thereby created, and the process is repeated until the electrons reach the wire. the resulting "avalanche" of electrons is collected by the wire, generating a signal that is used to record the passage of the original particle of radiation. suppose the radius of the central wire is 24 âµm, the inner radius of the shell 2.3 cm, and the length of the shell 14 cm. if the electric field at the shell's inner wall is 2.8 ă— 104 n/c, what is the total positive charge on the central wire?

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20
