You’ll need 4H20 molecules to balance the equation.
Explanation:
The angular momentum is given by the moment of inertia, multiplied by the angular speed of the rotating body:
The angular speed is given by:
Now, we calculate the angular momentum:
The average torque is defined as:
is the angular acceleration, which is defined as:
We have to calculate :
Now, we calculate the angular acceleration:
Finally, we can know the average torque:
¡Hola!
For this problem, first, lets recabe information:
v = 0 m/s
t = 3 s
g = 9,82 m/s²
v' = ?
d = ?
First, for calculate the final velocity:
v' = v + g * t
v' = 0 m/s + 9,82 m/s² * 3 s
v' = 29,46 m/s
Now, for calculate how far did it fall:
d = v * t + g * t^2 / 2
Like v = 0 m/s, we can simplificate equation:
d = g * t^2 / 2
d = 9,82 m/s² * (3 s)^2 / 2
d = 9,82 m/s² * 9 s² / 2
d = 88,38 m / 2
d = 44.19 m
¡Buena suerte!
As opposed to ionic bonding in which a complete transfer of electrons occurs, covalent bonding occurs when two (or more) elements share electrons. Covalent bonding occurs because the atoms in the compound have a similar tendency for electrons (generally to gain electrons).
Answer:
0.253 m
Explanation:
Given that, the mass of the particle, .
Charge of the particle, .
Speed of the particle, .
Magnetic field is, .
The radius of the particle's circular path when the speed of the particle is perpendicular to the magnetic field is,
.
By putting all the values in the above equation.
.
Therefore by further solving,
Therefore the radius of the particle in a circular path is 0.253 m
