The radius of Earth is maximum at the equator. So 'g' is minimum at equator. Hence the weight of a body is minimum at equator.
The weight of a body at the centre of earth is zero because value of g is zero. As we move a body closer to the centre of the earth, the mass of the earth between the centre of the earth and the body keeps decreasing.
In vacuum, there is no force of buoyancy, therefore weight is maximum in vacuum.
We know that weight depends on acceleration due to gravity 'g' and 'g' is inversely proportional to the radius of Earth. The radius of Earth is minimum at the pole. So 'g' is maximum at pole. Hence, the weight of the body is maximum at pole.
So the weight of the body is maximum at the poles and minimum at the equator on the surface of the earth.
For example, if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That's because Mercury weighs less than Earth, and therefore its gravity would pull less on your body.
There's fat inside our bodies in places you may not be aware of, like the brain, nerves, and surrounding organs. "It is impossible to have zero percent body fat," says Dr. Sutterer.
“I've never really seen anyone who really had zero body fat,” he said. “You just can't be. You wouldn't survive.” But it is possible to get down to so little body fat it becomes unmeasurable by standard methods, Columbia's Garber said.
Your body can meet the majority of your calorie requirements from stored fat, but total starvation is fatal in 8-12 weeks, regardless of initial body weight. Within one or two days of your last meal, your body will have exhausted all the glycogen stored in the liver and muscles.
Health Risks and Dangers of Low Body Fat in Adult Men and Women. Men who have less than 6 percent body fat and women with less than 16 percent body fat are considered too low.
A woman of average build, who exercises moderately intensively every day, burns about 2,000 kilocalories a day, and a man around 2,500 kilocalories. This means that you can live off your fat reserves for an average of 66 days (for a woman) or 53 days (for a man), as long as you don't become more active.
In general, the total body fat percentage (essential plus storage fat) is between 12% and 15% for young men and between 25% and 28% for young women {Lohman, 1993 #4151} (see also table 13.1). Average percentages body fat for the general population and for various athletes are presented in table 13.2.
Overdosing on HGH and insulin medications, or eating a very high-calorie diet, are two common ways that bodybuilders try to gain weight quickly. Insulin usage leads to increased fat accumulation inside and around the abdominal cavity, which in turn increases abdominal swelling.
Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s2, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s2. “Nevado was a bit surprising because it is about 1000 kilometres south of the equator,” says Hirt.
If you moved further toward its center, perhaps by venturing down into Death Valley, you'd be a fraction of a percent heavier. But the effect is much less than the difference between being on the equator and a pole. The Earth's radius at the equator is 6,378 kilometers.
Sri Lanka and south India has least gravity level on the earth. As you say this is almost the equatorial region and this area has minimal gravity as measured by the Sri Lankan government. The point on the Earth's surface with the lowest gravity is Hiriwadunna in Sri Lanka.
What % Body Fat Percentage is Needed to Reveal Your Abs? Having a six-pack requires a leaner physique - typically within the athletic range. The body fat percentage needed to see your pack of abdominal muscles falls somewhere around 14 to 20% for women and 6 to 13% for men.
For men, if you're around six to 17 percent body fat, your abs should be noticeably visible. For women, the range is 14 to 24 percent body fat. Definition will start to show on the higher end (17 percent for men, 24 percent for women), and your abs will become more sculpted as that number lowers.
The answer is yes, since even if the body could break down the fat deposits efficiently, there would be insufficient vitamins, minerals, and useful proteins for the body to sustain itself.
Altogether, it seems possible to survive without food and drink within a time span of 8 to 21 days. If a person is only deprived of food, the survival time may even go up to about two months, although this is influenced by many factors.
The recommended ranges for healthy men are between 10-20% body fat, and for women, the ranges are 18-28%. If your body fat exceeds these ranges, but you have a normal weight when you stand on the scale, you may be skinny fat.
The normal amount of body fat is between 25 and 30 percent in women and 18 and 23 percent in men. Women with more than 30 percent body fat and men with more than 25 percent body fat are considered obese.
