The general trend is that electronegativity increases as you go up and to the right on the periodic table
The total resistance of several resistors in series is their sum.
In this series circuit, it's (20 + 30 + 40) = 90 ohms .
Current = (voltage) / (resistance
Current = (20 V) / (90 ohms)
Current = 2/9 Ampere (0.222... A)
Refractive index of a medium = speed of light in vacuum

speed of light in that medium
Answer:
Explanation:
ω = 2π/ T = 2π/ 3.01 = 2.087 rad/s
x(t) = 0.290sin2.087t
v(t) = 0.290(2.087)cos2.087t
a(t) = -0.290(2.087²)sin2.087t
With these three equations, you should be able to plug in what you know to find other values
Answer:
Momentum of car = 1200 kg * 10 m/s = 12000 kgm/s Momentum = Force * time 12000 kgm/s = Force * 20s Force = 600 N
