Select the correct text in the passage. Which phrases describe the proper way to hold a chef knife?
Holding a Chef Knife
The Culinary School of Spain has a school newspaper where students can publish articles about their research. One of the articles mentioned
that 80 percent of the students said the proper way to hold a chef knife was to be gentle and tap on the edge slowly when cutting. The article
also indicated that 20 percent of students said another way to hold a chef knife was to be firm and use a one or two-finger pinch grip around
the top of the blade. The professors at the school were amused by the findings and decided to hold a demonstration at the cafeteria. During the
demonstration, the students learned how to use a chef knife with either hand,

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

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?
