Answer:
a) The magnitude of the current is 24.19 A
b) The angle is 90°
Explanation:
a) Given:
B = magnetic field = 44 µT = 44x10⁻⁶T
r = distance = 11 cm = 0.11 m
The current is:
b) Because the current flows from the west to the east, therefore, the angle is 90 degrees from the north.

A____is a grid that shows the potential offspring of two parents.
Punnett Square
B? I'm just guessing and I hope I'm right
Answer: A)C= 0.066F
B)Q= 23100C
C)Uc= 4×10³*³j
Explanation:
A) capacitance of a spherical capacitor
C =4 πϵ. R1 R2 ÷ R2 - R1
Where:
C: Capacitance
R1: radius to the earth surface which is 6400× 10³ m
R2: radius to the ionosphere is 6400 + 70 = 6470 × 10³ m
ϵ. : permittivity of free space is given as 8.85 × 10¹/¹² C²/N.m²
Potential difference a cross the capacitor is 350,000V
C= 4 π×8.85 × 10¹/¹² (6400× 10³ ×6470 × 10³ / 70×10³) = 0.066F
C= 0.066F
B) Total charge of the capacitor
C= Q/V
C: is the capacitance
Q: is the charge
V: P.d a cross the capacitor
Since we are solving for the total charge Q= CV
Q= 0.066 × 350000 = 23100C
Q= 23100C
C) the energy stored in the system
Uc = 1/2 QV
Uc = 1/2 ×23100 × 350000 = 4×10³*³j
Uc= 4×10³*³j
