Answer:
Current is half
Voltage is half
Explanation:
according to Ohms law V = IR
Case 1
I₁ = V / R
I₂ = V / (R+R) = V / 2R
∴ I₁ / I₂ = (V/R) / (V/2R)
=> I₁ / I₂ = (V/R) * (2R/V)
=> I₁ / I₂ = (2VR / RV)
I₁ / I₂ = 2
I₂ = I₁ / 2
The current through each resistor in the two-resistor circuit is half the current through the resistor in the one-resistor circuit (the circuit in Part A).
The voltage across each resistor in the two-resistor circuit is half the voltage across the resistor in the one-resistor circuit.
Answer:
let us use the expression v = ./2gS in both the cases.
a) In the first case g = 9.8 m/s^2 and S = 10.3 m.
So v = 14.21 m/s
b) in the second case, g = 1.64 m/s^2 and S = 4.2 m = 3.71 m/s

Explanation:
They compare the structure of the organisms, and they use the information about the chemical makeup of the organisms cells.
Answer:
Equations for speed, velocity and acceleration depend on change of position over time. Average speed uses the equation "speed equals distance traveled (d) divided by travel time (t)," or average speed = d ÷ t. Average velocity equals speed in a direction
We also learned that speed is a scalar quantity, which is one that requires only a magnitude, while velocity is a vector quantity, which is one that requires a magnitude (also mph) and a direction. The rate of change for velocity is acceleration, which is measured in displacement over time over time (e.g., m / s^2).

Answer:
90 ohms
Explanation:
1/r = 1/180 + 1/180
1/r= 2/180
take the reciprocal of 2/180 which is 180/2 and its 90 ohms
