Answer:
A. .
Explanation:
By definition of Electric Capacitance, the capacitance of the system (), in farads, is described by the following formula:
(1)
Where:
- Electric charge, in coulombs.
- Voltage, in volts.
If we know that and
, then the capacitance of the system is:
The correct answer is A.
Answer:
E = 1.64 x 10⁶ V/m
Explanation:
The electric field in the region between the plates can be given by the following formula:
where,
E = Electric Field = ?
ΔV = Poetential Difference across the plates = 23 KV = 23000 V
d = distance between plates = 1.4 cm = 0.014 m
Therefore, using these values in the equation, we get:
<u>E = 1.64 x 10⁶ V/m</u>
Answer:
mass = 0.44 Kg
Explanation:
given,
Calories contain in the strawberry yogurt = 255 calories
1 Calorie = 4186 J
latent heat of vaporization = 2.42 x 10⁶ J/Kg
mass of perspiration = ?
Energy = 255 calories
Energy = 255 x 4186
= 1067430 J
Energy = mass x latent heat of vaporization
mass = 0.44 Kg
