what? Is there a picture you can show us with this question
The formula for weight is
W = mg = 9.81m, where m is the mass
Now, according to Newton's 2nd Law of motion,
F = ma
Since it is mentioned that the weight is now 0.66 of the original,
0.66W = ma
0.66(9.81m) = ma
Cancelling out m,
a = 0.66(9.81)
a = 6.47 m/s²
Since the weight is only a fraction of the original, it means that some of the weight is lifted off through the action of the elevator moving down. Thus, the direction of the acceleration is moving down.

Both the magnet and the coil moving toward each other at 10 cm/s each
A reversed polarity magnet moving away from the coil at 20 cm/s

Explanation:
![\omega _{0} = 82\ rad/s](https://tex.z-dn.net/?f=%5Comega%20_%7B0%7D%20%3D%2082%5C%20rad%2Fs)
![\alpha = - 1.4\ rad/s^{2}](https://tex.z-dn.net/?f=%5Calpha%20%3D%20-%201.4%5C%20rad%2Fs%5E%7B2%7D)
![\Theta = ?](https://tex.z-dn.net/?f=%5CTheta%20%3D%20%3F)
![\omega _{f} = 0\ rad/s](https://tex.z-dn.net/?f=%5Comega%20_%7Bf%7D%20%3D%200%5C%20rad%2Fs)
![2*\alpha *\Theta = \omega _{f}^{2}-\omega _{0}^{2}](https://tex.z-dn.net/?f=2%2A%5Calpha%20%2A%5CTheta%20%3D%20%5Comega%20_%7Bf%7D%5E%7B2%7D-%5Comega%20_%7B0%7D%5E%7B2%7D)
![2*-1.4*\Theta = -82^{2}](https://tex.z-dn.net/?f=2%2A-1.4%2A%5CTheta%20%3D%20-82%5E%7B2%7D)
![\Theta = 2401.429\ radian = 2401.429*\frac{\pi }{180}\ degree = 41.91\ degree](https://tex.z-dn.net/?f=%5CTheta%20%3D%202401.429%5C%20radian%20%3D%202401.429%2A%5Cfrac%7B%5Cpi%20%7D%7B180%7D%5C%20degree%20%3D%2041.91%5C%20degree)
Each number in the wheel spans 360/12 = 30 degree
Therefore 41.91 degree corresponds to the number 29 on the wheel when the wheel spins clockwise.
Answer:
Option B
Explanation:
Maintenance-free battery uses Recombination Electrolyte in order to limit the oxygen and hydrogen formation during charging.
Each plate of the battery uses a glass micro-fiber separator that absorbs the whole liquid electrolyte in its pore thus resulting in no free acid.
As the battery charges to its fullest, the oxygen produced at the positive plate moves via the pores of the separator to the negative plate.
Initially it reacts and forms
, i.e., Lead Sulphate, then on further charging it gets converted to Pb, i.e., lead.
Due to this, the negative plate is not able to reach the correct potential in order to liberate hydrogen, and hence no water formation takes place.
Thus technician B is correct.
