Answer: D
Explanation: D is the most reasonable answer because it's always good to plan ahead for anything, so if you were to plan ahead for future obstacles, then you can overcome them.
Answer:
c. metallic, sub metallic, or nonmetallic
Answer;
= 0.244 seconds
Explanation;
500 rpm is equivalent to; 1500 × 2π radians per minute
= 9424.8 rad/minute
To get revolutions per second we divide by 60
= 9424.8/60
= 157.08 radians per second.
Then we divide by 64.3 rad/s^2 to get time;
= 157.08/64.3
= 0.244 seconds.
66.7 Watts
Explanation:
Let 
ohms, 
ohms and 
ohms. Since 
and 
are in parallel, their combined resistance 
is given by
or
The total current flowing through the circuit <em>I</em> is given
where
Therefore, the total current through the circuit is
In order to find the voltage drop across the 6-ohm resistor, we first need to find the voltage drop across the 1-ohm resistor 
:
This means that voltage drop across the 6-ohm resistor 
is 20 V. The power dissipated <em>P</em> by the 6-ohm resitor is given by
We know, F = k * q₁ * q₂ / r²
Substitute the known values,
F = 9 * 10⁹ * 5 * 7 / (1.2)²
F = 315 * 10⁹ / 1.44
F = 218.75 * 10⁹ N
F = 2.1875 * 10¹¹ N [ Final Answer ]
Hope this helps!
