A mass of 1.5 kg weighs 14.7 newtons (3.31 pounds) on the surface of the earth,
and 2.4 newtons (8.6 ounces) on the surface of the moon.

No. That would be a very light bicycle
15 cubic feet of what? - Different substances have different densities. There is no general conversion between volume and mass (or volume and weight).
Density equal to mass over volume, so you would have to divide 15 over 5 equal to 3 grams per cubic cm

The mass of 14 books in a box would depend on the individual weight of each book and the weight of the box itself. Without specific weights to provide an accurate calculation, we would need more information to determine the total mass.
This cannot be sensibly answered. A litre is a measure of volume, kg is a measure of weight or mass.
about 35 pounds ---- Kilometers is a measure of DISTANCE (say, how far is it from Paris to London), not weight (say, an apple weighs more than a ping-pong ball). If you meant "how much weight is 15 kiloGRAMS" than that would be equivalent to roughly 15 x 2.2 = 33 US pounds. If you meant "how much DISTANCE is 15 kilometers than that would be 15 divided by 1.6 = 9.375 miles. Best wishes! Tom
Kilograms are a measure of mass, as opposed to 'weight.' You would weigh 35 pounds, or 155 newtons, on the moon. This would feel like 15 kilograms on earth.
No, milligrams is a measure of mass, mililitres is a measure of volume15 ml of water would weigh 15 milligrams.====================================Oops ! 15 ml ofr water would weigh 15 grams
While mass can be a measure of weight in day to day use (ie The box weighed 15 kg) technically it is actually a measure of how much gravitational force an object exerts. This is how the term mass is used in physics.
Gravity (acceleration) is equal to Force divided by mass. So, 126 / 15 = 8.4m/s^2
You need mass (weight is commonly used and will work just about OK) and volume. A 5000 kg mass with a volume of one cubic metre has a density of 5000 kg/m3, and this would convert to 5 kg/litre. A 15 pound mass with a volume of one cubic foot has a density of 15 lb/ft3.
The ideal weight for a female of 15 years old 5'5" would be 122 lbs. The ideal weight for a male of 15 years old 5'5" would be 125 lbs. The current person's BMI is at 15 A healthy BMI (Body Mass Index) would be between 19 - 25 This suggests that the person is under weight But every individual is different and unique and depending on said persons medical conditions it can affect one's weight. One should consult their physician before being any diets or other plans.
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 be 90 kg, but your weight would be one sixth of that, 15 kg. Weight is the force of attraction exerted on you by the moon or the earth, whichever you happen to be standing on. In science and engineering mass is described in kilograms, while weight (force) is measured in Newtons which goes back to Newton's second law of motion: force equals mass times the rate of change of momentum. In most cases that can be simplified to force equals mass times acceleration. A force of 1 Newton causes a 1 kg mass in free motion to increase its speed by 1 meter per second every second. In practice on the earth's surface a 1 kg mass has a weight of 9.81 Newtons, but in everyday language we say its weight is 1 kg because that works for everyone who is not an astronaut :).
If your mass is 40kg on Earth, you would weighabout 392 Newtons depending on your location. This is because the Earth exerts 9.8 Newtons of gravitational force on a body per kilogram of that body's mass. In the US, you would say you weighed about 88 pounds.On Mars, a 40 kg person would weigh about 148 Newtons, or about 33 pounds.Because many countries now use SI units inappropriately, there is some confusion about the difference between mass and weight. If you are asking this question for a physics assignment, the answer is 40 kg, but that would be your mass, not your weight. If you are asking because you want to know what it would be like on Mars, you could say that you would feel like you were 15 kg on the equator of Mars...but actually you would feel heavier because you wouldn't have exercised your legs at all in about 6 months.Sources: High school physics, Wikipedia (Mars article) and Cornell.edu
