Vi = 4 m/s
vf = 22 m/s
t = 3s
a = ?
vf = vi + a * t
vf - vi = a * t
a = (vf - vi) / t
a = (22 - 4) / 3
a = 6 m / s^2
The correct answer is A. The strands are different. Hope this helps! :)
Answer:
Drift velocity in m/s is 
.
Explanation:
<em>Formula for Drift Velocity is</em>:
Where I is the current
n is the number of electrons in 1 
or the electron density
A is the area of cross section and
q is the charge of one electron.
We are given the following:
n = 
I = 1 A
A = 0.40 
= 40 
We know that q = 
Putting all the values to find drift velocity:
So, <em>drift velocity in m/s</em> is .
Explanation:
Noise is sound with a continuous structure. Music is composed of sounds with a fundamental frequency and overtones. Noise is composed of sounds with frequencies that range continuously in value from as low as you can hear to as high as you can hear — not necessarily at equal intensity, however.
Answer:
True
Explanation:
In a chemical reaction, if the reactants have more potential energy than the products have, the extra energy is released to the surroundings as heat. This type of reaction is exothermic.
The activation energy is the difference between the energy of the reactants and the maximum energy (the activated complex).
The activated complex is the complex that exists as the bonds in the products are forming and the bonds in the reactants are breaking. This Complex exists when the energy of the system is at its maximum.
