Answer:
The mass of an electron is actually 9.11x10-31
The proton is bigger (heavier) by about 1836 times
All forces of energy are useful at home, like friction, friction can let us grip to the ground, or mechanical energy, used in cars because cars move, and computers same thing you move the mouse, type and do way more. Energy is always around us.
Answer:
The correct option is: a. Photosphere
Explanation:
Sun is the brightest star in the sky of our planet Earth and the principle component of the Solar System. It is a <u>gaseous object</u> that is made up of hot plasma and contributes 99.86% to the total mass of our Solar System.
<u>The Sun does not have a clearly defined surface.</u> The <u>visible surface of the Sun is known as the Photosphere</u>, which is the deepest visible portion of the Sun.
Answer:
Explanation:
Step 1
The question is based on the concept of PH and pOH calculations.
pH is defined as negative logarithmic of hydronium Ion concentration.
while pOH is defined as negative logarithmic of hydroxide ion concentration of the solution.
Step 2
[H+] = 7.7*10-7 M
pH = -log[H+]
= -log ( 7.7*10-7 )
= 6.12
Step 3
pOH = 14 - pH
= 14 - 6.11
= 7.89
