Answer:
Violet
Explanation:
Wavelength spectrum of visible light for the range of 390nm to 460nm is seen as violet. So the violet colour will be seen and reflected as what the eyes will see
Layer F was formed earlier than Layer A
It is a because it is inversely proportional
Answer: 15.83 m^3
Explanation:
This problem is about ideal gases.
Given that volumen, pressure and temperature, you must think about using the combined law of gases.
This is how you solve the problem.
1) Data:
V1 = 10m^3
p1 = 760 mmHg
T1 = 27°C = 27 + 273.15 K = 300.15K
p2 = 400 mmHg
T = - 23°C = - 23 + 273.15 K = 250.15 K
V2 = ?
2) Formula
pV/T = constant =>
p1 * V1 p2 * V2
---------- = -----------
T1 T2
3) Solution
=> V2 = p1 * V1 * T2 / (T1 * p2)
V2 = 760 mmHg * 10m^3 * 250.15 K / (300.15K * 400 mmHg)
V2 = 15.83 m^3.
Answer:
Resistance become infinite
Explanation:
In series circuit when switch is closed then a current is flow which is equal to 
, here V is voltage and R is resistance
But when switch is open then no current is flow in the circuit
So 
, this is possible when resistance become infinite
So when switch is open then resistance of the circuit will become infinite
