Given that
Force (F) = 15 N ,
mass (m) = 5 Kg ,
acceleartion = ?
We know that, From Newtons II law
F = m. a
15 = 5 × a
a = 15÷ 5
a = 3 m/s²
acceleration of the ball is 3 m/s²
The answer to this question is dropping it on a hard surface.
The right answer is Q).
Explanation:
P) Depicts organ level of organization.
R) Depicts cellular level of organization.
S) Depicts Organ System level of organization.

The Capacitive reactance of a capacitor is dependent upon the frequency. The lower the frequency, the higher the reactance, the higher the frequency, the lower the reactance. The equation is
Xc = 1/(2*pi*f*C)
where
Xc = Reactance in ohms
pi = 3.1415926535.....
f = frequency in hertz.
C = capacitance in farads.
I'm assuming that the voltage and resistor mentioned in the question are for later parts that are not mentioned in this question. Reason is that they have no effect on the reactance, but would have an effect if a question about current draw is made in a later part. With that said, let's calculate the reactance.
The 120 rad/s frequency is better known as 60 Hz.
Substitute known values into the formula.
Xc = 1/(2*pi* 60 * 0.00000480)
Xc = 1/0.001809557
Xc = 552.6213302
Rounding to 3 significant figures gives 553 ohms.</span>
