Which Of The Following Comparisons Correctly Describes Subatomic Particles?, A. An Electron Has A Negative Charge And A Mass Larger Than The Mass Of A

Which of the following comparisons correctly describes subatomic particles?

A. An electron has a negative charge and a mass larger than the mass of a proton.

B. A neutron has a negative charge and a mass smaller than the mass of a proton.

C. A neutron has a neutral charge and a mass larger than the mass of an electron.

D. A proton has a positive charge and a mass smaller than the mass of an electron.

 

The following comparisons correctly describes subatomic particles :

C. A neutron has a neutral charge and a mass larger than the mass of an electron.

Further explanation

An atom is the smallest material consisting of a nucleus, which contains protons, neutrons, and electrons that surround it  

Protons are positively charged (+1), electrons are negatively charged (-1). and neutrons are uncharged (neutral)  

While the mass of 1 proton is equal to the mass of 1 neutron, equal to 1 amu and the electron has a mass smaller than both.  

The hydrogen atom is the lightest atom whose mass is 1.67 x 10⁻²⁷kg (measured using a mass spectrometer) and simplified to 1 amu (atomic mass unit).  

1 amu = 1,66.10⁻²⁴ grams  

The mass of each basic particle :

  • electron mass = 9.11.10⁻²⁸ grams  
  • proton mass = 1.6726.10⁻²⁴ grams  
  • neutron mass = 1,675.10⁻²⁴ grams

So electrons have the smallest mass compared to protons and neutrons

Then the correct answer should be :

A. An electron has a negative charge and a mass smaller than the mass of a proton.

B. A neutron has a neutral charge and have the same mass as a proton.

D. A proton has a positive charge and a mass larger than the mass of an electron

Ano Ang Ibig Sabihin Ng Nagbubuhat Ng Sariling Bangko

Ano ang ibig sabihin ng nagbubuhat ng sariling bangko   Ang pag-upo sa gitna ng publiko ay isang kapakumbabaa yamang binigyan mo ng pagkakataon ang iba na magsalita o manguna. Ngunit ang isa na nagbubuhat ng bangko ay ang isang na hindi naman binigyan ng pagkakataon upang magsalita ngunit nagmamataas o nagyayabang. Kadalasan na maroon naman siyang masasabi, pero ang paraan ng pagsasalta ay nauuna o naiiba siya mula pa sa iba.

The length, width and diagonal of a rectangular parallelepiped are 13.4ft., 15.2ft., and 35ft. respectively. Find the volume of the solid.   Answer: The answer to this problem is V = 5813.03 Step-by-step explanation: First, a drawing is needed to full understand the problem. See attached photo. Figure 1 shows the dimensions of the rectangular parallelepiped including the variable h for height and x for the hypotenuse of the length and width. In  order to calculate the volume of this solid, we need to find h. But before we get h, we must first calculate the x. Refer to figure 2. We can see that it forms a right triangle. Since x is the hypotenuse of the length and width, we will use Pythagorean theorem to solve it. Now refer to figure 3. Since the diagonal, the height and x is forming a right triangle, we can also use Pythagorean theorem to solve h. Finally, we can solve the volume of the solid.
