Answer:
The time constant τ = L/R represent the time requiered for the curent to get value of 63 % of its maximun value
Explanation:
In a circuit RL ( serie circuit with a resistor R and the inductor L ) when a voltage is applied the inductor will have a reaction, such reaction consist in the creation of an electromotive force which will prevent the current to get its maximun value. The time constant which in the case of an inductor is
τ = L/R , represent the time requiered for the crrent to be 63 % of its final value
The <u><em>voltage</em></u> at the input to the hair dryer is
V = (current) · (resistance)
V = (15 A) · (8 Ω)
<em>V = 120 volts</em>
<em>__________________________________</em>
The <em><u>power</u></em> dissipated by the hair dryer is
P = (current)²· (resistance)
P = (15 A)² · (8 Ω)
<em>P = 1800 watts </em>

Answer:
The advertisement feature that George can use is a coupon booklet with the local newspaper for delivery
Explanation:
George focus on promotion rather than using the other stores strategy of word-of-mouth. Different types of promotion: advertising, public relations, direct selling and sales promotions.A temporary reduction in the price, such as 50% off. Reduction amount may be a percentage that can be marked on the package.A coupon booklet is inserted into the local newspaper for delivery. Also on checkout the customer can be given a coupon based on products purchased. The consumer is automatically entered into the contest/event by purchasing the product.
Displays:-

There is a difference between dragand friction. Friction is relatively constant at different velocities whiledrag increases with speed. Forexample, when you rub your hands together at different speeds, the force of friction remains the same although the heat generated will vary.
