3x + 1 ≤ 1
Subtract 1 from each side: 3x ≤ 0
Divide each side by 3 : <em>x ≤ 0</em>
Explanation:
The total resistance Rt is given by
1/Rt = 1/Ra + 1/Rb + 1/Rc = 1/5 + 1/4 + 1/7 = 0.593
or Rt = 1.69 ohms
The total current I running through the circuit is
I = V/Rt = 2.37 A
Explanation:
For North America,
Power, P = 26 W
Voltage of AC razor, V = 120 V
For Europe,
Voltage of AC razor, V' = 220 V
The power of razor in North America is given by :
Let P' is the power consumed by razor in Europe. Now,
So, the razor consumed 87.38 watts of power as it is ruined.
Answer:
Use the principle of momentum
Initial momentum = final momentum
Momentum formula = Mass * Velocity
Explanation:
Answer:
It looks yellow because that is the only (major) color reflected.
Visible spectra is from about 4000-7000 Angstroms (10^-10 m).
Red are longer wavelengths and blue are the shorter wavelengths.
The Sodium doublet (yellow) occurs around 5900 Angstroms.
