Sink. It's density will be greater than water, which is 1 kg per litre.
On Earth, 20kg is 196 newtons or 44.1 lbs.
If an object with a mass of 20 kg is on the surface of the earth or near it, then the object and the earth are attracting each other with a force of 196 newtons (44.1 pounds).

The mass of a 20kg object is 20 kilograms. This means that the object has a certain amount of matter that exerts a gravitational force of about 196.2 Newtons (assuming acceleration due to gravity is 9.81 m/s^2).
20kg on earth has a force of 196N
The force exerted by the floor of the lift on the object will be the sum of the gravitational force acting downwards and the force necessary to accelerate the object downwards with the lift. The magnitude of the force will be the sum of the object's weight (mg) and the force due to acceleration (ma), which equals (20kg * 9.81 m/s^2) + (20kg * 4 m/s^2) = 196.2N + 80N = 276.2N.
On Earth, 20kg is 196 newtons or 44.1 lbs.
If an object with a mass of 20 kg is on the surface of the earth or near it, then the object and the earth are attracting each other with a force of 196 newtons (44.1 pounds).
PE=mgh 980=mx9.81x5 m=20kg
The density of the object is calculated by dividing its mass by its volume. In this case, density = mass/volume = 20kg / 50l = 0.4 kg/l.
20x G(gravitational constant 9.81ish) 20x9.81=196.2 Newtons
An object with a mass of 20 kg weighs about 196 Newtons (44 pounds) on earth.
Momentum is the product of the mass and velocity of an object. Momentum= Mass x Velocity. When the object weighs 20kg and is traveling at 20m/s North it will have a momentum of 400kgm/s North.
About 20kg of force.
This depends greatly on how dense the solid product is, since some solids have a greater amount of air-pockets than others. A 20kg solid with lots of air pockets (so not very dense) will lead to a smaller amount of liquid than a 20kg solid with very few air pockets (a dense solid).
