Which of the following statements correctly describes the relation between frequency, wavelength energy and velocity of a wave t

Sedbober [7]

The statement that correctly describes the relation in the question is ; ( A ) As wavelength decreases, frequency increases, energy increases and the speed remains the same.

The Frequency of a wave travelling in a medium is directly proportional to the energy produced by the wave and inversely proportional to the wavelength of the wave.

Changes in the wavelength and frequency of a wave has no effect on the wave speed. but has an effect on the energy produced by the wave. therefore the wave speed remains constant regardless of the changes in wavelength and frequency

Hence we can conclude that As wavelength decreases, frequency increases, energy increases and the speed remains the same.

RoseWind [281]

Answer: (The question is incomplete) The human body is made up of different organs. An organ is a group of tissues in a living organism that have been adapted to perform a specific function. The different organs in the body can work together to perform a similar function. These groups of organs performing a common function constitutes an organ system. For example, the circulatory system which is responsible for transporting blood throughout the body, consists of the heart and blood vessels known as veins, arteries and capillaries.

Explanation:

The hypothalamus which is part of the endocrine system organ synthesizes and secretes regulatory hormones.

The skeleton which is part of the Skeletal system supports Body and Anchors Muscle.

The blood which is part of the Circulatory (cardiovascular) system transports substances throughout the body including the heart.

The respiratory system exchanges Oxygen and CO₂ between body and air.

The Muscular system is an organ system consisting of muscles which permits movement of the body.

The immune system of the body defends the body against diseases.

The lymphatic system functions to keep body fluid levels in balance and to defend the body against infections. It includes thymus and spleen.

The excretory system rids body of liquid waste. It includes the skin, the kidney and urethra, the bladder, and two ureters.

The digestive system which includes the stomach, the liver, anus, large and small intestine,e.t.c, breaks down food and absorbs nutrients.

The nervous system processes sensory information and controls responses. It includes the brain & spinal cord which form a part of the nervous system called the central nervous system (CNS)
