Answer:
A1 = 3A, A2 = 1.5A
Effective resistance = 2Ω
Explanation:
When the switch is closed, the voltage across each resistor is 6V, so the current through it (A2) is ...
A2 = 6V/(4Ω) = 1.5A
There are two parallel paths, each with that current, so the current from the battery is ...
A1 = A2 +A2 = 1.5A +1.5A = 3.0A
Then the effective resistance is ...
Reff = 6V/(3.0A) = 2.0Ω
The solution to the circuit is ...
A1 = 3A, A2 = 1.5A
Effective resistance = 2Ω

Answer:
E > A = B > C > D
Explanation:
On a semicircular curve, the magnitude of force is given by the formula as :

Here, m is the mass of the vehicle
Case A : R = 60 m v = 16 m/s

Case B : R = 15 m v = 8 m/s

Case C : R = 30 m v = 4 m/s

Case D : R = 45 m v = 4 m/s

Case E : R = 30 m v = 16 m/s

The order of the magnitude of the force of the roller-coaster track on the cart from largest to smallest is :
E > A = B > C > D
