An object with the mass of 2.0 kg accelerates 2.0 m/s2 when an inknown force is applied to it what is the amount of the force

Ivahew [28]

As per Newton's II law we know that

$F = ma$

here F = force applied

m = mass of object = 2 kg

a = acceleration = 2 m/s^2

now as per above formula we will have

$F = 2 \times 2$

$F = 4 N$

so here applied force on the ball will be 4 N

The secondary coil of a step-up transformer provides the voltage that operates an electrostatic air filter. The turns ratio of t

Sphinxa [80]

Answer:

The power consumed by the air filter is 9.936 watts

Explanation:

It is given that, the secondary coil of a step-up transformer provides the voltage that operates an electrostatic air filter.

Turn ratio of the transformer, $\dfrac{N_s}{N_p}=\dfrac{46}{1}$

Voltage of primary coil, $V_p=120\ V$

Current in the secondary coil, $I_s=1.8\times 10^{-3}\ A$

The power consumed by the air filter is :

$P_s=I_s\times V_s$ ...........(1)

For a transformer, $\dfrac{N_s}{N_p}=\dfrac{V_s}{V_p}$

So, $P_s=I_s\times (\dfrac{N_s}{N_p})\times V_p$

$P_s=1.8\times 10^{-3}\times (\dfrac{46}{1})\times 120$

$P_s=9.936\ Watts$

So, the power consumed by the air filter is 9.936 watts. Hence, this is the required solution.
