Calculate the electric field (in V/m) between two parallel plates connected to a 45 V battery if the plates are separated by a)

Sonja [21]

Answer:

Explanation:

Given

Voltage of battery $V=45\ V$

electric field(E) is given by

$E=|-\frac{dV}{dx}|$

i.e. Change in Potential over a distance x

(a)When Plate are separated by 3 cm apart

$E=|\frac{45}{3\times 10^{-2}}|$

$E=1500\ V/m$

(b)When Plates are 5 cm apart

$E=|-\frac{45}{5\times 10^{-2}}|$

$E=900\ V/m$

Force on electron is given by

$F=charge\times Electric\ Field$

$F=q\times E$

For case a

$F=1.6\times 10^{-19}\times 1500$

$F=24\times 10^{-17}\ N$

(b) $F=1.6\times 10^{-19}\times 900=14.4\times 10^{-17}\ N$

Answer:

e. Decreased; Increased

Explanation:

The market equilibrium refers to the condition in which the price and the quantity are in equilibrium if the conditions of supply (what the producers offer) and demand (what the consumers buy) don't change.

In this case we have that as the other kids decide to sell more lemonade the amount of lemonade is going to increase (equilibrium quantity) and because of this the price is going to decrease (equilibrium price).

Then when the other kids open theirown lemonade stand, the equilibrium price descreased and the equilibrium quantity increased.
