<u>Answer:</u> Electron has almost no mass.
<u>Explanation:</u>
Mass is defined as the actual matter that is contained in a substance. At an atomic level, it is expressed in atomic mass units.
The given options are the 3 subatomic particles.
Mass of the given subatomic particles are:
Proton = 1.007276u
Neutron = 1.008664u
Electron = 0.0005485u
Mass of neutron is slightly more than the mass of proton.
From the above information, it is visible that electron has a negligible mass.
Hence, the correct answer is electron.
The density is the ratio between mass and volume. So the mass is the product between density and volume. But! You have to control the units of measure.
7.85 g/l = 0.00785 kg/l
41.25 ml = 0.04125 l
Mass = (0.00785) x (0.04125) = 0,00032381 kg ---> 0,32381 g
(I hope this is right )
The magnetic field is believed to be generated by electric currents in the conductive material of its core, created by convection currents due to heat escaping from the core. So your answer is A
Answer:
Released
Explanation:
When particles that attract each other come together, energy is usually released. The combination of the two particles is expected to result in a lower energy system. This lower energy system will be more stable than the different individual particles.
Hence, as this lower energy system is formed, the excess energy originally possessed by the particles is evolved hence energy is released when particles that attract each other are allowed to come together.
Answer:
5
Explanation:
The image attached shows the different monochlorination products obtained when chlorine gas is heated with methylcyclobutane.
We must keep in mind that the reaction occurs by free radical mechanism as shown in the image attached. The proportion in which the products are formed depends on the stability of the free radical intermediate leading to that particular product.
