They must have mass. This is not a particularly stringent or discriminatory requirement.
A probability must needs be a number between 0 and 1 (often expressed as 0% and 100%), inclusive.
x and y must both be positive.
Weigh your self. For some reason people seem to think Stone and KG are your weight however weight does not exist, it only exists because of gravity hence must be measured in Newtons (N). See the link if you want to work out your weight from your mass.
To get to five, there must be more than two objects. However, there are only two objects being added to two other objects. That answer is four, not five.
he believed if you can doubt it, it must not exist.
To reduce the force of gravity for any given pair of objects, the objects must be at a greater distance from each other.
No, that would mean the Earth didn't exist any more. The fact that the Earth is spinning is not the cause of its gravity. Every object has gravity that pulls other objects towards it - even a pen, a desk or a house (but they only have tiny amounts). If gravity "stopped" the Earth must have shrunk or disappeared.
Gravity pulls them down. Newtons Law of Gravity: what goes up must come down. objects fall to the ground because of gravity
In order for that to happen, one object must be positive mass and the other one must be negative mass. Negative mass has never been observed yet, so gravity has never been observed to push objects apart.
Two objects must be touching and it has to transfer heat

He didn't. The word gravity was in use in the English language by about 200 years before Newton developed his theory of gravity. People already knew that gravity made objects fall, Newton just gave a highly accurate insight into how gravity works. Newton was 44 years old when he published is Principia in which He laid out his theory. These are his main contributions:described gravity as an attractive force between all objects with mass that is directly proportional to the objects and inversely proportional to the square of their distances.He proposed that gravity not only made objects fall on Earth but was the attractive force that kept the various celestial objects in their orbits.Newton's formulation of gravity is so accurate that it is even used to plot the trajectories of spacecraft. It is only in instances of extreme speed or density or when extreme precision is needed that scientists must use general relativity to describe gravity.
They believed an agreement must exist between the people and their leaders
air resistance
1. The two objects are to be in thermal contact. This means that everything between the two objects must be a conductor. 2. There is to be a temperature difference between the two objects. One must be hotter than the other. Given these two conditions, heat will pass from the hotter to the cooler object. That is one of the fundamental laws of thermodynamics.
Um... "block wave"? Do you mean "black hole," and if so how did you manage that typo?Anyhow, they're predicted by theory, and these things predicted by theory would have certain characteristics, and lo and behold there are objects out in space that appear to have exactly those characteristics. Ergo, black holes must exist, and these objects must be them.
