What is the mass in kilograms of 1 l of water? what is its weight in newtons? Weight: In physics, weight is equal to the force due to gravity acting on an object and it is measured in Newtons (N). The weight of an object can be found by multiplying its mass ...
Considering that the whole universe has originated from a sphere with a big bang, I will give you the diameters of popular astronomical objects in our solar system as well as the Universe. You can have an idea how big the universe is.Earth's Moon - 3500 KmMercury -4900 kmMars - 6800 ...
If the concentration of mercury in the water of a polluted lake is 0.33 micrograms per liter, what is the total mass of mercury in the lake, in kilograms? The lake has a surface area of 10.0 km^2 and a...
Ganymede is a Jovian moon, Jupiter's largest satellite, and the largest satellite in the solar system. With a diameter of 5262 km, it is larger than Mercury, although with only half Mercury's mass. Along with Io, Europa, and Callisto, Ganymede is a Galilean moon, meaning it was ...

In summary, mass is the quantity of matter per unit volume and is the cause of the force of gravity. It can be defined as the product of density and volume, but this definition can be circular and does not fully clarify the nature of mass. Einstein's theory of special relativity equate...
A wind with a velocity of 37km/hr blows toward 67.0 degrees. What is the wind's velocity towards 90.0 degrees? If you divide velocity by acceleration what would the units of the result (in metric) be? If you are driving 55.0 miles per hour, what is your speed in meters per second?

With a mean radius of24,622 ± 19 km, Neptune is the fourth largest planet in the Solar System. But with a mass of1.0243 × 1026kg –which is roughly 17 times that of Earth – it is the third most massive, outranking Uranus. Due to its smaller size and higher concentrations of vola...
science team member david thompson of nasa's goddard space flight center said in a nasa statement. related: what is a black hole event horizon (and what happens there)? how do neutron stars form? the life of a star, no matter its size, is a balancing act between the inward "push" ...
