I would say D. all of the above
It's called a concave lens.
Answer:
-27.3 m/s
Explanation:
Given:
y₀ = 38 m
y = 0 m
v₀ = 0 m/s
a = -9.8 m/s²
Find: v
v² = v₀² + 2a (y − y₀)
v² = (0 m/s)² + 2 (-9.8 m/s²) (0 m − 38 m)
v = -27.3 m/s
Or, you can solve with energy.
PE = KE
mgh = ½ mv²
v² = 2gh
v = -27.3 m/s
Answer:
0.536 A
Explanation:
From the question,
The combined resistance of the parallel connection is given as
1/Rt = 1/4+1/6+1/10
Rt = 120/15
Rt = 8 ohms.
Since the the combination is connected in series with a 10 ohms resistor,
Rt' = 8+10 = 18 ohms.
Current flowing through the series circuit
I = V/Rt'
V = 12 V, Rt' = 18 ohms
I = 12/18
I = 0.67 A.
Therefore voltage across the combined resistor
V' = 8(0.67)
v' = 5.36 V.
Since the resistors a connected in parallel, the same voltage drop across them.
Therefore, current through the 10 ohms
Ix = 5.36/10
Ix = 0.536 A
