The formula for finding the kinetic energy of an object is:
KE = 0.5MV^2,
Where:
M= Mass
V = Speed
From the information given above,
M = 21 kg
V = 3 m/s
KE = 0.5 * 21 * 9 = 94.5
Therefore, the canoe's kinetic energy is 94.5 J
Answer:
One gram of protein has 4Kcal of calories. Proteins should represent between 10 and 15% of daily energy intake. An adult needs daily 0.8 grams of protein per kilogram of body weight. Children, pregnant women, nursing mothers, athletes, and older adults need a little more protein.
Explanation:
<span>You needed a quick boost of energy - MONOSACCHARIDE
You wanted to grow strong nails, you haven't eaten in days - PROTEIN
You wanted to grow healthy hair - PROTEIN
You had a race tomorrow afternoon - POLYSACCHARIDE
You were getting ready for hibernation - LIPIDS
You wanted to get bigger muscles - PROTEIN
Your meal will be in a week - LIPIDS
CARBOHYDRATES include monosaccharide and polysaccharides. They provide immediate energy boost or short term energy storage for animals as well as long term energy storage for plants.
PROTEIN s</span>peeds up chemical reactions by lowering activation energy. It is used to form bones and build muscles. It is m<span>ade up of an amino group, a carboxyl group, and an R group.
LIPIDS can be saturated or unsaturated fatty acids. They are not soluble in water however they provide long-term energy storage for animals. </span>
Answer:
True
