Complete Question
A parallel-plate capacitor, with air dielectric, is charged by a battery, after which the battery is disconnected. A slab of glass dielectric is then slowly inserted between the plates. As it is being inserted,
A :
a force repels the glass out of the capacitor.
B :
a force attracts the glass into the capacitor.
C :
no force acts on the glass.
D :
a net charge appears on the glass.
E :
the glass makes the plates repel each other.
Answer:
The correct option is B
Explanation:
Generally when the glass dielectric is slowly inserted between the plated,
The positive plate of the capacitor will induce a negative charge on the glass while the negative plate of the capacitor will induce a positive charge on glass which a electric field that posses an electric force that will attract the glass
Answer:

Explanation:
= Emissivity of the panel = 1
= Stefan-Boltzmann constant = 
T = Temperature = (273.15+6)
Area of the panel is given by
The power radiated is given by
The power radiated from each panel is 4462.0927 W
Answer:
3a, 2b,4c,1d
Explanation:
what do I need to explain just something you know
Each vegetables and fruits will have different response to the varying temperature and atmospheric condition of the surrounding. Some may become rotten in a shorter period of time. In this regard the price would get lower in order for the goods to get sold easily.
