Answer:
The molecules of different liquids have different size and mass. The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid. Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter.
Explanation:
Weight = (mass) x (acceleration of gravity) .
Acceleration of gravity on a planet's surface is proportional to
(planet's mass) / (planet's radius)² .
On Earth's surface, acceleration of gravity is 9.8 m/s² .
Weight of 10 kg mass = (10 kg) x (9.8 m/s²) = 98 newtons.
On the surface of a planet with twice the Earth's mass
all stuffed into the same radius, the acceleration of gravity
would be 19.6 m/s² ... double what it is on Earth.
Weight of 10 kg would be (10 kg) x (19.6 m/s²) = 196 newtons ...
double its Earth weight.
Answer:
0.25 m
Explanation:
a = v² / r
4.0 m/s² = (1.0 m/s)² / r
r = 0.25 m
The percent complete is calculated by dividing the quantity of material progressed at a point in time by the total quantity required for the project. The resulting percent is multiplied by the current agreed committed value of the material item to obtain the VOWD for that item.
The calculation of the centripetal acceleration of an object following a circular path is based on the equation,
a = v² / r
where a is the acceleration, v is the velocity, and r is the radius.
Substituting the known values from the given above,
4.4 m/s² = (15 m/s)² / r
The value of r from the equation is 51.14 m.
Answer: 51.14 m
