Answer:
25 cm²
Explanation:
Meters and centimeters are both the units for measuring length. The SI unit of measuring length is meters.
Area is the quantity which measures the cross-section occupied by the object.
Thus,
Given that = Area = 0.0025 m²
To convert into cm²
1 m = 100 cm
So, 1 m² = 10000 cm²
So,
<u>Area = 0.0025 × 10000 cm² = 25 cm²</u>
Answer:
w= p∆v 50000 ( 0.55-0.40) and calculate and you get it
Answer:
1.925 μC
Explanation:
Charge: This can be defined as the product of the capacitance of a capacitor and the voltage. The S.I unit of charge is Coulombs (C)
The formula for the charge stored in a capacitor is given as,
Q = CV ................... Equation 1
Where Q = charge, C = Capacitor, V = Voltage.
Note: 1 μF = 10⁻⁶ F
Given: C = 0.55 μF = 0.55×10⁻⁶ F, V = 3.5 V.
Substitute into equation 1
Q = 0.55×10⁻⁶×3.5
Q = 1.925×10⁻⁶ C.
Q = 1.925 μC
Hence the charge on the plate = 1.925 μC
