<u>5. False</u>
Explanation:
1. Indeed, many health experts often recommend that when children reach the age of adolescents (between ages 10 and 19) they should eat a variety of foods daily in other to have enough energy and nutrients needed for development.
2. Having regular meals (mornings, afternoon, and evenings) has for long been encouraged by medical professionals in other to provide the body its fuel.
3. Some skin problems have long been associated with too much consumption of sweets and desserts since these products often contain sugars, and excess processed sugar intake is said to increase acne and eczema.
4. Just as the name suggests, the food pyramid is a visual representation that contains how many servings from each food group in other be healthy.
5. This is false because throughout the growth stages of life it is essential to get the needed food nutrients such as calcium, iron, protein, and energy foods.
<span>1 pound is equal to .454 kilograms.
115 pounds equals
115 x .454 kilograms = 52.163 kg.
The total dose is equal to the dose per kilograms multiplied by the total mass in kilograms.
6.00mg/kg x 52.163kg = 312.978mg.
The total dose is 313.0 mg</span>
The new speed of the glider is 42.2 m/s.
The new speed of the glider can be calculated using the principle of the law of conservation of energy.
Note: Total energy of the glider before the dive = Total energy of the glider after the dive.
<h3> Formula:</h3>
- mv²/2+mgh = mV²/2 +mgH................ Equation 1
Simplifying the equation above,
make V the subject of the equation.
- V = √[(v²/2)+gh]-gH]............... Equation 2
<h3>Where:</h3>
- V = New speed of the glider
- v = initial speed of the glider
- h = initial height of the glider
- H = New height of the glider
- g = acceleration due to gravity.
From the question,
<h3>Given:</h3>
- v = 40 m/s
- h = 300 meters
- H = 200 meters
- g = 9.8 m/s²
Substitute these values into equation 2.
- V = √[(40²/2)+(9.8×300)-(9.8×200)]
- V = √(800+2940-1960)
- V = √1780
- V = 42.2 m/s.
Hence, The new speed of the glider is 42.2 m/s.
