3.Halley
4. Halley urged newton to write Principia mathematica and when the Royal society declined to pay the cost of publishing Halley paid for it out of his own pocket
5.Through using a telescope Galileo Galilei was able to prove the theories of sciences Isaac newton
6. He believe that the speed of an object motion is proportional to the force being applied and inversely proportional to the density of the medium he reason that the object moving in a void would move in definitely fast and thus any and all objects
7. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force

Answer:
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest) or a push and pull motion.
Explanation:
Answer:
Option E
RbCL<CH3OH< CH3Cl< CH4
Explanation:
The boiling temperature of an organic compound increases with the increase in number of carbon atoms and hence as the length of the hydrocarbon chain increases the boiling temperature also increase due to increase in force of attraction between the molecules. Also presence of strong molecules such as OH – COOH also increases the boiling temperature while Cl and other elements with high electronegativity reduces the boiling temperature
Hence, the correct order of increasing boiling temperature is option E
RbCL<CH3OH< CH3Cl< CH4
Answer:
Protons
Explanation:
Typically protons cannot be removed from the atom. Removing protons from an atom will completely change the atom as it will become another element entirely.
In an atom, protons are held by strong nuclear forces.
- Within an atom, protons are the positively charged particles.
- Together with the neutrons, they are found in the nucleus of an atom.
- The number of protons within an atom is the atomic number of the atoms and it determines the nature and type of atom it is.
- Protons cannot be removed from an atom due to the strong binding force holding them together in place.
