As accurately described by Einstein's theory of relativity, gravity is not necessarily a force, but a consequence of the curvature of space time that is caused by the uneven distribution of mass. But this could also be approximated by Newton's Law of Universal Motion. Gravity is a force acting upon two objects with masses at a certain amount of distance. So, the greater the mass, and the closer the objects are, the greater is the force of gravity.

Now, gravitational force in Earth is equal to 9.81 m/s². But its value on the moon is different: 1.622 m/s². In this case, your weight changes depending on where you are because the gravitational force will vary. According to Newton's Second Law of Motion, F = mg. Weight is describe as the force that pulls you toward the center of an object. So, weight = mass × gravity. Mass is constant, but gravity is not. Thus, that is how weight changes when gravity also does.

When the temperature of a sample of liquid increases , what else increases ?
Lubov Fominskaja [6]

Answer:

Its kinetic energy.

Explanation:

In a liquid, the molecules are so close together that there is very little empty space. A liquid also has a definite volume, because molecules in a liquid do not break away from the attractive forces. The molecules can, however, move past one another freely, and so a liquid can flow, can be poured, and assumes the shape of its container.

An increase in the temperature of a liquid causes an increase in the average speed of its molecules. As the temperature of a liquid increases, the molecules move faster thereby increasing the liquid's kinetic energy.

Describe what happens to a carbon-11 atom when it undergoes positron emission.
atroni [7]

Answer:C11 -----^boron+positron

Explanation:the above reaction is nuclear reaction.

Positron emission causes the decrease in atomic number by one.

As in above example carbon-11is converted into boron isotop which has atomic number of 5.

Why is it unnecessary to include an aluminum trihalide in electrophilic aromatic bromination reaction of acetanilide wih molecul
Helen [10]
Many electrophilic aromatic halogenations require the presence of an aluminum trihalide as a catalyst. We generally acetylated the amino group as protection. Now, this acetanilide can be brominated at Ortho or para position. An atom that is attached to an aromatic system usually hydrogen is replaced by an electrophile is an organic reaction which is called Electrophilic aromatic substitution. There are what you called important electrophilic aromatic substitutions they are aromatic nitration, aromatic sulfonation, aromatic halogenation and acylation and alkylating Friedel-Crafts reaction. Aromatic bromination is an electrophilic aromatic substitution (EAS) reaction, which will require benzene to act as a nucleophile to acquire an electrophile. Therefore, any directing groups that activate the ring will make it react more quickly with respect to aromatic bromination. Acetanilide is a moderately-activated ring <span>having a decent EWG.</span>
