Answer:
a. 3.0 m/s^2
b. 18N
Explanation:
force = mass times acceleration
a.
box 1
24 = 2 times acceleration
24 divided by 2 = acceleration
acceleration = 24 divided by 2
acceleration = 12
box 2
24 = 6 times acceleration
24 divided by 2 = acceleration
acceleration = 24 divided by 6
acceleration = 4
acceleration is averaged
(2+4)/2 = 3

b.
its saying
in f = ma
if you have the same m of 6
and the a of 3
what is the force?
6 times 3 = 18
18 N
Because tropical moist forests are used for agricultural, the thin soil cannot support continuous cropping, while deciduous forests can regrow quickly.
The reactance of an inductor is given by:
X = 2πfL
X is the inductor's reactance
f is the frequency of the supplied voltage
L is the inductor's inductance
The given values are:
f = 60.0Hz
L = 43.8mH (I'm assuming the value is given in milli Henries because this is within the normal range of inductors)
Plug these values in and solve for X:
X = 2π(60.0)(43.8×10⁻³)
X = 16.512Ω
Round this value to 3 significant figures:
X = 16.5Ω
The relationship between AC voltage and current is given by:
V = IZ
V is the voltage
I is the current
Z is the impedance
For an AC inductor circuit, Z = X = 16.512Ω and V is the rms voltage 120V. Plug these values in to get the rms current:
120 = I×16.512
I = 7.2673A
Round this value to 3 significant figures:
I = 7.27A
