Correct me if I’m wrong but I think it’s C
Answer:
Explanation:
0.2 rev/s = 0.2 rev/s * 2π rad/rev = 0.4π rad/s
Since the angular acceleration is assumed to be constant, and the wheel's angular speed is increasing from rest (0 rad/s) to 0.4π rad/s within 23.8s. Then the angular acceleration must be
The french revolution led to many deaths and impacted history because of the amount of life lost
Kirchhoff's circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff. This generalized the work of Georg Ohm and preceded the work of Maxwell.
. The formula for methane is CH4. There are 8 total valence electrons - 1 each for the hydrogen atoms, and 4 for the carbon atom. There are four single bonds, and no lone electron pairs in the methane molecule. With 8 valence electrons and 4 single bonds, we get 8/4=2 electrons per bond.
<span>2. The methane molecule contains four single, or sigma, bonds. Each sigma bond is formed between the 1s orbital of a hydrogen atom, which contains one electron, and one of the four hybrid sp3 orbitals of the carbon atom, each of which contains one electron. That gives us 2 electrons per bond.
