What supplies the body with energy for building and repairing tissues?

What supplies the body with energy for building and repairing tissues?

Your digestive system changes carbohydrates into glucose (blood sugar). Your body uses this sugar for energy for your cells, tissues and organs. It stores any extra sugar in your liver and muscles for when it is needed. There are two types of carbohydrates: simple and complex.

What is the most essential nutrient for building and repairing cells and tissues?

Proteins

Which of the following nutrients is responsible for repair and tissue building?

Protein is a nutrient used to make and repair our body cells (like blood and muscle cells). About 1/2 of your dry body weight is protein. If you do not eat enough carbohydrates, protein will be changed to carbohydrates so that you can get energy.

How do you calculate the energy content of food?

The equation for calculating the energy content of a food source via calorimetry is as follows: Energy (joules) = Mass of water (g) × 4.2 (J/gºC) × Temperature increase (ºC)

How do we calculate energy?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

How do you calculate time with mass and distance?

Work is the force exerted on an object times the distance over which the force is exerted: W = Fx, where W is the work in Nm = Joule. Work done to lift an object of mass m a height h: W = Fgh = mgh.

What should my weight be for my height and age?

Measure your waist-to-height ratio To calculate the WtHR, a person should divide their waist size by their height. If the answer is 0.5 or less, the chances are that they have a healthy weight. A woman who is 5 feet and 4 inches tall (163 cm), should have a waist measurement below 32 inches (81 cm).

What is the formula to calculate mass?

What Is The Formula For Mass?

  1. mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume.
  2. mass=force÷acceleration (m=F/a).
  3. mass=weight÷gravitational acceleration (m=W/g).

What is your mass on Earth?

To find an object’s mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G).

How do you convert n to mass?

Divide the newtons by the rate of acceleration, which will give you the mass of the object. The mass will be in kilograms, because a single newton represents the amount of force needed to move one kilogram one meter. For our example, we will divide 10 N by 2 m/s/s, which give us a mass of 5 kg.

How would your mass on the moon compare to your mass on Earth?

It is also defined as the force of gravity acting on the object. Therefore, the mass of an object on the Moon remains the same as its mass on Earth. But its weight gets less because the gravity on the moon is less than on the Earth.

Is KG a weight or a mass?

The kilogram is the SI unit of mass and it is the almost universally used standard mass unit. The associated SI unit of force and weight is the Newton, with 1 kilogram weighing 9.8 Newtons under standard conditions on the Earth’s surface.

How much is your true weight if the scale shows 100 kg?

Newtons. The correct unit for force is the Newton (=1 kg·m/s2) which is abbreviated N. So a 100 kg mass really weighs about 980 Newtons on Earth.

How does mass affect weight?

As your body grows, you will have more mass, which also means you will weigh more. That’s because when you’re on the earth, the amount of gravity that pulls on you stays the same. So when your mass changes, so does your weight!

Why kg is used for weight?

In other words, the weight(force) of one kg is equal to one kgf, or 9.8N. Since there is no practical easy way to measure mass, in everyday life we use the kilogram as a unit of weight assuming that the gravitational field is fairly constant around earth.

How many pounds means 1 kg?

What is your weight in kg?

Pounds to Kilograms conversion table

Pounds (lb) Kilograms (kg) Kilograms+Grams (kg+g)
0 lb 0 kg 0 kg 0 g
0.1 lb 0.045 kg 0 kg 45 g
1 lb 0.454 kg 0 kg 454 g
2 lb 0.907 kg 0 kg 907 g

What does weight in kg mean?

A dictionary has a mass of about one kilogram. Kilograms are often written as kg (that is a “k” for “kilo” and a “g” for “gram), so “10 kg” means “10 kilograms”. Scales measure our weight using kilograms. An adult weighs about 70 kg.

What is a 100 weight in kg?

The short hundredweight or cental of 100 pounds (45.36 kg) is used in the United States. The long or imperial hundredweight of 8 stone or 112 pounds (50.80 kg) is defined in the imperial system.

What does 4 kg mean in pounds?

8.8184905 Pounds

How do I convert kg to lbs?

There are 2.lb in 1 kilogram. To convert kilograms to pounds, multiply your figure by 2

Which is more 1kg or 1 lb?

1. Pound is an imperial unit of mass or weight measure while kilogram is a metric unit of measurement. One kilogram is approximately equal to 2.2 pounds. So a kilo is 2.2 times heavier than a pound.

What is 12 lbs 8 oz to the nearest kg?

5.675 Kilograms

What does 10 kg mean in pounds?

Pounds

What does 72 kg mean in pounds?
