He produced the first orderly arrangement of known elements, he used patterns to predict undiscovered elements
Answer:
8.97 Watt
Explanation:
Resistance, R = 20 ohm
Inductance, L = 10 mH
V(t) = 20 Cos (1000 t + 45°)
Compare with the standard equation
V(t) = Vo Cos(ωt + Ф)
Ф = 45°
ω = 1000 rad/s
Vo = 20 V
Inductive reactance, XL = ωL = 1000 x 0.01 = 10 ohm
impedance is Z.


Z = 22.36 ohm



Apparent power is given by
P = Vrms x Irms
P = 14.144 x 0.634
P = 8.97 Watt
<em>Another key factor that determines a star's colour is its temperature. As stars become hotter, the overall radiated energy increases, and the peak of the curve changes to shorter wavelengths. To put it another way, when a star heats up, the light it produces moves toward the blue end of the spectrum.</em>
The answer is, "B", "Ammonia".
Many firms develop a formal marketing plan to answer the question: who is your target market and how do you plan to reach them. A marketing plan is a comprehensive document which sets out an organization's overall marketing strategy. A marketing plan will include digital media, print media as well as product development strategies. The marketing plan takes the organization's mission statement and turns it into a practical plan. Its goal is to practically implement the reason for the organization's existance.
