Answer:
Explanation:
For parallel inductors , 



For series combination 
Total inductance 
= 16.67 + 20 
= 36.67 mH . 
reactance of total inductance at 300 kHz 
= ω where ω is angular frequency
 where ω is angular frequency 
= 2πf
= 2 x 3.14 x 300 x 10³ x 36.67 x 10⁻³ 
= 69.1 x 10³ ohm 
Total rms current = Vrms / reactance 
= 60 / 69.1 x 10³ A 
= .87 x 10⁻³ A 
= .87 mA

Answer:
3.42N
Explanation:
*not too sure bc i left my physics notes at school so it might not be 100% accurate :p*
Use the equation: F = (GMm)/(r^2)
F = force of gravity
G = gravitational constant (6.7x10^-11)
M = mass1 (2.5x10^30kg)
m = mass2 (1kg)
r = radius (7000m)
Plug it in: F = ((6.7x10^-11)(2.5x10^30)(1)) / (7000^2)
F = (1.675x10^20) / (4.9x10^7)
F = 3.4183673x10^12
F = 3.42N
 
        
             
        
        
        
 Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.Displacement<span> is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
</span>To calculate displacement<span>, simply draw a vector from your starting point to your final position and solve for the length of this line. If your starting and ending position are the same, like your circular 5K route, then your </span>displacement<span> is 0. In physics, </span>displacement<span> is represented by Δs.
 
 For me to solve this I would need to know the time, but I can give you a handy displacement calculator I used that helped me.

I'm quite certain the answer is "stress".
