Answer:
Perceptual
Explanation:
This is the level of awareness that is needed to know position and movement by the five senses.
Answer:
37.7 Ω
Explanation:
The resistance in each lamp is:
P = IV = V²/R
R = V²/P
R₁ = (110 V)² / (150 W)
R₁ = 80.67 Ω
R₂ = (110 V)² / (200 W)
R₂ = 60.5 Ω
Their combined resistance in parallel is:
1/R = 1/R₁ + 1/R₂
1/R = 1/(80.67 Ω) + 1/(60.5 Ω)
R = 34.57 Ω
So the current that goes through them is:
V = IR
I = V/R
I = (110 V) / (34.57 Ω)
I = 3.182 A
We need the same current in the new circuit.
V = IR
230 V = (3.182 A) (R₃ + 34.57 Ω)
R₃ = 37.7 Ω
We can check our answer by finding the voltage drop across this resistor:
V = I R₃
V = (3.182 A) (37.7 Ω)
V = 120 V
230 V − 120 V = 110 V, the correct voltage for the lamps.

Answer:
the answer is C
Explanation:
i took the test just now so i am glad i can help someone in the future❣❣❣❣
<u><em>Also here is the explanation</em></u>
Note that the magnitude of acceleration (a) is given by a =
v2
R
, where v is the speed and R is the radius. Because acceleration is the same for both bikers, the ratio 
v2
R
, also has to be the same for both. Given that Kevin’s speed is higher, the radius of his path must also be higher to maintain the same ratio. Therefore, Kevin’s circular path has a bigger radius than Linda’s path.
Answer:
The answer to your question is below
Explanation:
T = °K
Kinetic energy
Temperature is the measure of the kinetic energy of molecules, the higher the temperature the higher the kinetic energy.
When the temperature is 0°K the molecules will not move and the kinetic energy will be zero.
If the temperature is 373°K the molecules will move fast and the kinetic energy will also be high.
