Gravity works on tiles.
Gravity or gravity is the attraction that occurs between all particles that have mass in the universe. Sun's gravity causes celestial bodies to be in their respective orbits around the sun. Modern physics describes gravity using Einstein's Theory of General Relativity, but Newton's simpler universal law of gravity is a fairly accurate estimate in many cases.
For example, the earth which has a very large mass produces a very large gravitational force to attract objects around it, including living things, and objects that exist on earth. This gravitational force also attracts objects in space, such as the moon, meteors, and other celestial bodies, including man-made satellites.
Kinetic energy or motion energy (also called kinetic energy) is the energy possessed by an object because of its motion.
The kinetic energy of an object is defined as the effort needed to move an object with a certain mass from rest to a certain speed.
The kinetic energy of an object is equal to the amount of effort required to express its speed and rotation, starting from the others.
Modern research in the theory of gravity began with the work of Galileo Galilei in the late 16th century and early 17th century. With the results of his experiments dropping the ball from the Tower of Pisa, and then also measuring the ball sliding through the slope, Galileo showed that the magnitude of gravitational acceleration was the same for all objects. This is a big advance from Aristotle's earlier belief that heavier objects have greater gravitational acceleration.

Astronomers give stars names so that they're able to identify and keep track of them more easily.
atoms are made of particles that have a negative charge.
electrons in atoms must have varying amounts of energy.
electrons are only found in the nucleus.
Using a cathode ray tube, Thomson confirmed that atoms are made of particles that have a negative charge., therefore the correct answer is option B
There are some models that are used to explain the arrangements of subatomic particles inside the atom based on the atomic theory of atom are known as the atomic models.
J.J. Thomson discovered using cathode ray tubes that something emits from the negative plate (referred to as the cathode) and travels towards the positive plate (referred to as the anode), and that when zinc sulfide (also known as a phosphor) coating is applied to the perforated anode, it exhibits green fluorescence at a specific pressure and temperature values.
Thus,by using a cathode ray tube, Thomson confirmed that atoms are made of particles that have a negative charge., therefore the correct answer is option B

Option (B) is correct .i.e. atoms are made of particles that have negative charge.
Further explanation:
Using cathode ray tube, J.J Thomson found that something emits from the negative plate (called as cathode) and goes towards the positive plate (called as anode), and on applying zinc sulfide (also called phosphor) coating on the perforated anode, it shows green fluorescence at some particular values of pressure and temperature.
William Crookes called them the cathode rays as were originated from cathode. Further, Atoms are overall neutral having equal amounts of positive and negative charge as he explained in his plum pudding model.
Although, electrons in atoms have varying energy but this was not confirmed by J.J. Thomson, also electrons can’t be inside nucleus because this would make atoms very unstable.
Some of the properties of those cathode rays are as follows:
(1). They are made up of material particles (they made the light wheels rotate that come in their path).
(2). The green fluorescence was also observed when he putted two more plates perpendicular to the earlier path and the rays followed a curved path towards the new anode.
(3). They has an ionizing property (they ionizes the gas present in the cathode ray tube, through which they pass).
Thus, Option (B) is correct because the cathode rays are emitted from the metallic plate which’s atoms have particles having negative charge.
