Because electrons are the only piece of the atom that is outside of the nucleus. the protons and neutrons are inside the nucleus.
then also the electrons itself have the charge to begin with
Answer:50%
Explanation: put it you are in a hurry
At 1.70 atm, a gas sample occupies 4.25 liters. If the pressure in the gas increases to 2.40 atm, what will the new volume be?
Answer:
3.01L
Explanation:
Given parameters:
Initial pressure, P1 = 1.7atm
Initial volume, V1 = 4.25L
Final pressure, P2 = 2.4atm
Unknown:
Final or new volume, V2 = ?
Solution:
To solve this problem, we use Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".
P1 V1 = P2 V2
P1 is the initial pressure
V1 is the initial volume
P2 final pressure
V2 final volume
1.7 x 4.25 = 2.4 x V2
V2 = 3.01L
Answer:
Explanation:
Distance traveled by light = 2 x 550 m = 1100 m
time taken by light to travel this distance = 1100 / 3 x 10⁸
= 366.67 x 10⁻⁸ s
angle between two consecutive slots = 2π / 500 rad
= .004π
angular velocity of wheel = angle moved / time taken
= .004π / 366.67 x 10⁻⁸
= 1091π radian / s
b ) linear speed of a point on the edge of the wheel
= ω R , r is radius of wheel , ω is angular velocity.
= 1091π x 5 x 10⁻²
= 1712.8 m /s
A eclipse starts when one object in space is blocking an observer. Most commonly known as the moon blocking the sun. For us having a visual on eclipses we normally have two eclipses. We have the solar eclipse and the lunar eclipse. These are both very important on the timing and the cycles of the moon. A solar eclipse happens when the moon moves in front of the sun. This will cause a shadow to fall on only a few certain places on earth. Then a lunar eclipse is when the Sun, moon, and earth are perfectly aligned. With the earth being the middle the Sun casts its rays and causes a huge shadow on the moon.
Hope this helped!
