to find the answer what you need to do is use a scale to measure how much the both objects shape that is how you can find your answer.
Put weight on it
The weight of the object causes gravity to take the object falling
It depends on the density of the water and the weight of the object.
You can't compare WEIGHT with MASS - those two are used to measure quite different things. It doesn't make sense to say that they are the same, or that they are different. You can only compare mass with mass, or weight with weight.
If an object's mass is exactly zero, then the object does not exist. No mass means no atoms. However, an object can have no weight and still have a mass. The weight depends on the gravitational force.
weight of object in water = (Mass of object) time acceleration of gravity - Mass of an equal volume of water times acceleration of gravity. note weight of object in water can be a negative value.
No. Density is a factor of weight and volume.
Yes it does make it easier by using a fulcrum Yes it does make it easier by using a fulcrum
Because of buoyancy ; something that acts in the opposite direction to the force of gravity to make the object feel lighter.
No, the object pronoun "EN" is invariable. You could compare it to the English "some / any".
You can't compare the mass and the weight. They are different types of things, so comparing them is like comparing, say, a unit of length (like the meter, or foot) with a unit of time (like the second, or hour). Therefore, it doesn't make sense of saying that the mass is "equal to" or "different from" the weight.
Because the weight on the object is a force that is measured in newtons (N) and that is gravitational force x mass / mass x 10. Basically, the weight is pushed down on the object which causes the object to move slightly faster than it normally would.
