Answer:

Here you go!

Explanation:

Gamma rays have the highest energy radiation and have the smallest wavelength in the electromagnetic spectrum.  They are formed by the hottest and most energetic objects in the world, with nuclear explosions, lightning and far less radioactive decay activity producing gamma rays. It can be both useful and dangerous, gamma rays are used in medicine to treat cancer with radiation when exposed to them, radiology, sterilization and much more.

Answer:

Gamma Rays

Explanation:

Gamma rays have the highest energy radiation and have the smallest wavelength in the electromagnetic spectrum. Gamma rays are ionizing electromagnetic radiation, obtained by the decay of an atomic nucleus. Gamma rays are more penetrating, in matter, and can damage living cells to a great extent. Gamma rays are used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry.

The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer.

notka56 [123]

Answer:

Velocity(v) = frequency(f) × wavelength

f = 0.3165

Wavelength = 2×length(L)

L = 157cm

Convert the length in centimetres to metre = 1.57m

v = 2×1.57 × 0.3165

v = 0.99m/s

Approx. 1m/s

Explanation:

The velocity of a wave is the product of its frequency and it's wavelength. The frequency is already known. The wavelength is the distance between two successive wave crests which is formed by sloshing water back and forth in the bath tub. Sloshing water to one end of the tub will produce a wave crest first at that end then the other completing a cycle. The wavelength will be twice the length of the bath tub as it is the distance that both crests are formed.

Wave crest is the highest point of a wave, and in this case is where the water rises to a high point in the bath tub

Los ácidos nucleicos y las proteínas comprenden una red de biomacromoléculas que almacenan y transmiten información que sustenta la vida de la célula. El estudio de estos mecanismos es un campo llamado biología molecular. El desarrollo de esta ciencia siempre ha ido acompañado de avances técnicos que permiten romper barreras metodológicas para probar hipótesis novedosas. Entre los métodos disponibles para los biólogos moleculares, destacan cinco: electroforesis, secuenciación, clonación, transferencia y reacción en cadena de la polimerasa. Su impacto llega a la genética, la medicina y la biotecnología. Aquí, se revisan la relevancia histórica, los fundamentos técnicos y las tendencias actuales de estos cinco métodos esenciales. La revisión pretende ser útil tanto para estudiantes como para científicos profesionales que buscan adquirir conocimientos avanzados sobre el valor de estos métodos para investigar los mecanismos moleculares que sostienen la vida.

Which type of motion does a wooden block NOT have when sliding down a hill? Question 1 options: A. Vibrational B. Rotational C.
nlexa [21]

Answer - the correct option is option B rotational

Explanation-  

A block that is sliding Downloads on inclination can have vibrational movement due to certain ups and downs or inequalities on on the surface. It will have frictional force due to the aberrations present in the surfaces of both block and Road and it will have transitional motion acting as the block's position is changing from one point to another the only motion.

It doesn't have is rotational because rotational  movements happen with circular objects only.
