A 20.0 Ω, 14.0 Ω, and 6.00 Ω resistor are connected in parallel to an emf source. A
current of 8.00 A is in the 14.0 Ω resistor Calculate the equivalent resistance of the
circuit.
Answer in units of Ω.
b) What is the potential difference across the
source?
Answer in units of V
c) Calculate the current in the 20.0 Ω resistor.
Answer in units of A.

D) Calculate the current in the 6.00 Ω resistor.
Answer in units of A.

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.

total distance/total time

(85 + 82)/(5+3)

20 just over

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
