Hi bobbym,

The Answers #5321 and #5322 are correct. Excellent!

#5323. Name the moving part of a rotary electrical switch in certain types of electric motors or electrical generators that periodically reverses the current direction between the rotor and the external circuit. They have two or more softer metallic brushes in contact with them to complete the other half of the switch. In a motor, it applies power to the best location on the rotor, and in a generator, picks off power similarly.

#5324. Name the device for measuring growth in plants. It was invented in the early 20th century by Sir Jagadish Chandra Bose - an Indian polymath, physicist, biologist, botanist, archaeologist. It uses a series of clockwork gears and a smoked glass plate to record the movement of the tip of a plant (or its roots) at magnifications of up to 10,000. Marks are made on the plate at intervals of a few seconds, demonstrating how the rate of growth varies under varying stimuli. Bose experimented with temperature, chemicals, gases and electricity.

Hi bobbym,

The Answer #5323 is correct. Excellent!

#5325. Name the instrument/appliance : A type of particle accelerator in which charged particles accelerate outwards from the center along a spiral path. The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying (radio frequency) electric field.

#5326. Name the instrument/appliance : It is a simple manual capacitive generator used to produce electrostatic charge via the process of electrostatic induction. A first version of it was invented in 1762 by Swedish professor Johan Carl Wilcke, but Italian scientist Alessandro Volta improved and popularized the device in 1775, and is sometimes erroneously credited with its invention.

#5327. Name the instrument/appliance : It is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first of its type, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600. They were used by the Austrian scientist Victor Hess in the discovery of cosmic rays.

#5328. Name the instrument : (Chemistry) A graduated glass tube used in the study and volumetric analysis of gas reactions.

#5329. Name the instrument : A device consisting of a spinning mass, typically a disk or wheel, mounted on a base so that its axis can turn freely in one or more directions and thereby maintain its orientation regardless of any movement of the base.

#5339. Name the instrument/device : An instrument used to measure the index of refraction of a substance in any one of several ways, such as measurement of the refraction produced by a prism, measurement of the critical angle, observation of an interference pattern produced by passing light through the substance, and measurement of the substance's dielectric constant.

#5340. Name the instrument/device : A communications device that amplifies (analog) or regenerates (digital) the data signal in order to extend the transmission distance. Available for both electronic and optical signals, repeaters are used extensively in long distance transmission.

Hi,

#5341. Name the instrument/gadget : An instrument that produces brief flashes of illumination at a variable frequency. The frequency can be synchronized or asynchronized with the frequency of a moving object, which can be made to appear stationary, to rotate slowly or to rotate in the opposite direction to its real rotation.

#5342. Name the instrument/gadget : Teleommunications) a telegraph apparatus consisting of a keyboard transmitter, which converts a typed message into coded pulses for transmission along a wire or cable, and a printing receiver, which converts incoming signals and prints out the message. US name: teletypewriter.

Hi bobbym,

The Answer #5341 is correct. Marvelous!

#5343. Name the insrument/gadget : In 1896, the first U.S. patent for an addressing machine, it was issued to Joseph Smith Duncan of Sioux City, Iowa. It was a development of the invention he had made in 1892. His earlier model consisted of a hexagonal wood block onto which he glued rubber type which had been torn from rubber stamps. While revolving, the block simultaneously inked the next name and address ready for the next impression.

#5344. Name the scientist : In 1852, he became the first person to make an engine-powered flight when he flew 27 km (17 mi) in a steam-powered airship (8 February 1825 – 14 April 1882). He was a French engineer. In 1852, he invented the steam injector and the powered airship. He was granted a patent for the injector on 8 May 1858. Unusually, he had thoroughly worked out the theory of this invention before making any experimental instrument, having explained the idea in 1850. Others had worked on using jets, particularly Bourdon who patented a very similar device in 1857

#5346. Name the U.S. inventor, entrepreneur and philanthropist (March 17, 1849 – June 15, 1929) . Born in Euclid Township, Ohio, he was raised on a farm about 10 miles from downtown Cleveland. He had a great interest in science, particularly with Humphry Davy's experiments with the arc light; he tinkered with and built simple electrical devices such as a static electricity machine at age 12, experimenting in a workshop on his parents farm. He attended Central High School in Cleveland where he built his first arc light, and graduated there with honors in 1867.
