A vector A~ has a negative x component 2.89 units in length and a positive y component 3.17 units in length. The vector A~ can b
1 answer:
Answer:
a1 = -2.89 units
a2 = 3.17 units
magnitude = 4.2896 units
direction = 132.35 degrees
Explanation:
We can write the vector in component form as: <-2.89, 3.17>
That means that its i and j components are:
a1 = -2.89 units
a2 = 3.17 units
The magnitude of the vector is given by:
The vectors direction can be found from the tangent function, ad noticing that the vector must reside on the Second Quadrant:

Complete question:
An air-filled parallel-plate capacitor has plates of area 2.90 cm2 separated by 2.50 mm. The capacitor is connected to a(n) 18.0 V battery. Find the value of its capacitance.
Answer:
The value of its capacitance is 1.027 x 10⁻¹² F
Explanation:
Given;
area of the plate, A = 2.9 cm² = 2.9 x 10⁻⁴ m²
separation distance of the plates, d = 2.5 mm = 2.5 x 10⁻³ m
voltage of the battery, V = 18 V
The value of its capacitance is calculated as;
Therefore, the value of its capacitance is 1.027 x 10⁻¹² F
