Answer:
Xc= 17.267 Ω, Z= 415.5 Ω, I= 0.537 A
Explanation:
Em = 223 V
f= 300 Hz, R = 222 Ω, L = 147 mH, C = 23.1 μF
a)
Capacitive reactance = Xc=?
Xc= 
Xc=1/2pi *399*23.1*10^-6
Xc= 17.267 Ω
b).
Z=
Xl= 2π * f * L
Xl= 2π * 399 * 147 * 
Xl= 368.5 Ω
Z=
= 
Z= 415.5 Ω
c).
Current:
I= V / Z= Em / Z
I= 223/415.5
I= 0.537 A
Potential Energy (Initial one) = m * g * h
P.E. = 60 * 9.8 * 10
P.E. = 5880
Kinetic Energy (Final One) = 1/2 mv²
K.E. = 1/2 * 60 * (10)²
K.E. = 6000/2
K.E. = 3000
Lost Energy = 5880 - 3000 = 2880 J
In short, Your Answer would be 2880 Joules
Hope this helps!
Answer:
Acceleration will be 
Explanation:
We have given final velocity v = 21.5 m/sec
Time t = 6.75 sec
As cheetah starts from rest so initial velocity u = 0 m/sec
From first equation of motion we know that v = u+at, here v is final velocity, u is initial velocity, a is acceleration and t is time
So 
The volume of the jet fuel is 1.213 x 10⁵ cm³.
<h3>What is density?</h3>
Density is a physical property that measures the ratio of mass to volume occupied by an object.
Density = mass/volume
Volume = mass/density
<h3> Volume of the jet fuel</h3>
The volume of the jet fuel is calculated as follows;
Volume = (97500 g)/(0.804 g/cm³)
Volume = 1.213 x 10⁵ cm³
Thus, the volume of the jet fuel is 1.213 x 10⁵ cm³.

Answer:
increased by 9 times
Explanation:
As the period of a simple pendulum is defined as the following formula

where L is the length of the pendulum and g is the constant gravitational acceleration. Since L is under a square root, if you want to triple the period of vibration, L must be increased by 9 times so that
