# If a student has a mass of 90 kg what is the students weight?

A mass of 90 kg weighs 882 newtons (198.4 pounds) on the earth. (rounded)

### What is gravity like on your planet using your mass in kg?

On my planet a man with a mass of 90 kg has a weight that is also 90 kg. On the Moon the same 90 kg man has a weight of 15 kg because the Moon is smaller and has less gravity. We distinguish between mass (amount of matter) and weight (a downward force) so that mass stays the same wherever the man is, even if his weight changes. Since Isaac Newton's time we know…

### What is the ratio to ninety students who ate hot dogs to the number of students who did not eat the hot dogs?

Fact: 90 students ate hot dogs Let Y be the number of students who DID not eat hot dogs (which is the unknown) Let Z be the total number of students in the universe (which is another unknown). Thus the ratio to ninety students who at hot dogs to ones that did not is generally provided by the following: z = 90 + y Thus 90+y:90 The answer is 90+Y to 90 Emre O

### What is the relation ship between mass and weight?

Mass is a quality of matter (apparently a construct of the Higgs field, but that's probably a little more answer than you were looking for). Weight is mass acted on by gravity. Mass is usually stated in units of kilograms. Weight can also be stated in kilograms, but is sometimes expressed in newtons. The mass stays constant, while the weight can change. If you are 90 kg, then on the moon your mass would still…

### What is 90 liters equal to in pounds?

A liter is a unit of volume, not a unit of mass (or weight) like the pound. To convert between mass and weight, you need to know the density of a substance. The formula that relates volume and mass is: mass = volume x density You'll probably find density in units such as kilogram / liter (or the equivalent gram/cubic centimeter); if you use this in the formula, you'll get the mass in kilograms. You…

### How does technology impact teachers?

My mother is a cooking teacher and she always complains about how every student brings their laptops in. she constantly has to set tasks on the computers and has changed her whole entire year plan to work on computers. every lesson a student asks "can we listen to music" but most of the time the students don't even ask! Most students do not realise that teachers are here to help them learn, even when the…

### Is 188 pounds a good weight for a 5' 7 13-year-old?

No, 188 pounds is not a good weight for you. According to BMI (Body Mass Index) standards, you are either very close to overweight, or obese (depending on your gender). For males, those statistics are considered obese (91 out of 90 percentile, 90 being obese), and for a female, it is just below obese (85 out of 90 percentile, 90 being obese).

### Why is the accurate molecular mass of many element not a whole number?

The atomic mass shown on the periodic chart is the weighted average of the naturally occurring isotopes of that element. It works like this: What is the average weight of 4 people where three weigh 120 and one weighs 90? (In this group, the most common weight is 120 so the average will be close to 120) The weighted average is: 75% x 120 + 25% x 90 = 90 + 22.5 = 112.5 All…
