Explanation:
The density of a rope, d = 7.5 g/cm³
The cross-sectional area of the rope, A = 2 cm²
The tension in the rope, T = 100 N
One end is vibrated up and down with a frequency of 25 Hz.
(a) The velocity of the transverse wave in the rope is given by :
Mass per unit length will be :
So,
(b) Let is the wavelength of the rope. So,
So, the velocity of the transverse wave in the rope is 2.58 m/s and the wavelength is 0.103 m.
Answer:
The correct answer is D. Nose and thyroid cartilages.
Explanation:
During puberty, many changes occur in the body of both males and females due to the change in hormonal balance and secretion. During adolescence, the male height is increased abruptly and their body starts becoming muscular.
In males during the puberty days, nose and thyroid cartilage enlarges disproportionately. The reason for disproportionate nose in males is that male requires more oxygen for muscles than females. In males, the thyroid cartilages enlarge more than females and responsible for vocalization in them. So the correct answer is D.
Answer:
Not enough personal income
Explanation:
Malnutrition refers to deficiencies, excesses or imbalances in a person's intake of energy and/or nutrients. The term malnutrition addresses 3 broad group of conditions:
- undernutrition, which includes wasting (low weight-for-height), stunting (low height-for-weight) and underweight (low weight-for-age);
- micronutrient-related malnutrition, which includes micronutrient deficiencies (a lack of important vitamins and minerals) or micronutrient excess; and
- overweight, obesity and diet-related noncommunicable diseases (such as heart disease, stroke, diabetes and some cancers).
In 2012, it was estimated that, using a poverty line of $1.25 a day, 1.2 billion people lived in poverty. Given the current economic model, built on GDP, it would take 100 years to bring the world's poorest up to the poverty line of $1.25 a day. UNICEF estimates half the world's children (or 1.1 billion) live in poverty.
Aspiration of Urine can be obtained by catherization. This procedure is performed by using a sterile urinary catheter inserted into the urethra into the bladder where gravity will pull the urine into a collection device. There is another type of aspiration that can be done using a very long needle inserted via puncture into the bladder but this is more invasive & not the first choice.
