As series resistors are added, the resistance is added directly so the total resistance will be equal to
Since the power is determined as
We have there that
The power is inversely proportional to the increase in resistance, so it will tend to decrease as more resistors are added in series.
The correct answer is: C.

Answer:
Free fall and air resistance
Answer:
259.274 kW
Explanation:
Given:
Area of the lava, A = 1.00 m²
Temperature of the surrounding, T₁ = 30.0° C = 303 k
Temperature of the lava, T₂ = 1190° C = 1463 K
emissivity, e = 1
Now,
from the Stefan-Boltzmann law of radiation the rate of heat loss is given as,
u = σeA(T₂⁴ - T₁⁴)
where,
u = rate of heat loss
σ = Stefan-Boltzmann constant = 5.67 × 10⁻⁸ W/m²∙K⁴
on substituting the respective values, we get
u = 5.67 × 10⁻⁸ × 1 × 1 × (1463⁴ - 303⁴)
or
u = 259274.957 W
or
u = 259.274 kW
Answer:
False
Explanation:
When a driver is impaired the brain will need an extra second or two to wake up, after it does wake up it tends to drift off regularly.
