The answer is -17x-1. You have to combine like terms.
Answer:
1:Radio waves are used to carry satellite signals. These waves travel at 300,000 km/s (the speed of light).
2:The standard methods of communication are speaking or writing by a sender and listening or reading the receiver. Most communication is oral, with one party speaking and others listening. ... A mixed message occurs when a person's words communicate one message, while nonverbally, he or she is communicating something else.
3: Today means of communication has increased such a lot that we can receive or send messages from or to far off places. Various means of communication which we use in the modern world are Posts and Telegraphs, Telephone, Radio and Television, Telex, Fax, Pagers, Email, Newspapers and cinema.
The rank of the capacitors in order of the energy they store is E>A>B>D>C.
<h3>
What is capacitor?</h3>
In an electric field, a capacitor is a device that stores electrical energy. It has two terminals and is a passive electrical component.
Capacitance refers to a capacitor's effect. While there is some capacitance between any two nearby electrical wires in a circuit, a capacitor is a component made to increase capacitance. The term "condenser" or "condensator" originally applied to the capacitor. Condenser microphones, sometimes known as capacitor microphones, are a remarkable exception to the general lack of usage of this name and its cognates in English.
Practical capacitors come in a wide variety of physical shapes and constructions, and there are numerous varieties that are used often.

Answer:
coefficient of kinetic friction= 0.502
Explanation:
Given Data
Speed 47.0 m/s
radius=1.25 m
moment of inertia=110 kg×m²
weight=1.40×10⁴N
time=0.47 s
To find
The Coefficient of Kinetic Friction
Solution
First to find initial angular speed in radian per second
angular speed w₀ = 47 / 1.25 = 37.6 rad /s.......as w₀=speed/radius
v= u+at
we have to find angular acceleration
as v=0 so
0 = 37.6 + 0.47a
a = -80 rad /s² shows it moves in anti clock wise direction
torque = Moment of Inertia * angular acceleration
t= 110 * 80
t= 8800 Nm
Now for friction force
friction force=t/radius
f f = 8800 / 1.25
f f= 7040 N
And finally to find coefficient of kinetic friction between the wheels and the runway
coefficient of kinetic friction=friction force/weight
coefficient of kinetic friction= 7040 / 1.4×10⁴
coefficient of kinetic friction= 0.502
