2. An alternating current is represented by the equation I=20sin 100mt.

Sladkaya [172]

Explanation:

The general equation of an AC current is given by :

$I=I_o sin\omega t$

Where

I₀ is the peak value of current

$\omega$ is angular frequency

$As\ \omega=2\pi f$

So,

$f=\dfrac{\omega}{2\pi}\\\\f=\dfrac{100\pi}{2\pi}\\\\f=50\ Hz$

We know that,

$I_{rms}=\dfrac{I_0}{\sqrt{2}}\\\\=\dfrac{20}{\sqrt{2}}\\\\I_{rms}=14.14\ A$

So, the frequency is 50 Hz and the maximum rms value of current is 14.14 A.

An animal-rescue plane flying due east at 49 m/s drops a bale of hay from an altitude of 66 m . The acceleration due to gravity

Gnoma [55]

Explanation:

The final velocity of the bale have vertical and horizontal components. So, we have:

$v^2=v_x^2+v_y^2(1)$

According to conservation of energy:

$\frac{mv_y^2}{2}=mgh\\v_y=\sqrt{2gh}$

Since the plane is flying due east, we have $v_x=49\frac{m}{s}$ . Replacing in (1):

$v=\sqrt{(\sqrt{2gh})^2+v_x^2}\\v=\sqrt{2(9,81\frac{m}{s^2})(66m)+(49\frac{m}{s})^2}\\v=60.78\frac{m}{s}$

Now, we calculate the momentum of the bale:

$p=mv\\p=\frac{160N}{9.81\frac{m}{s^2}}(60.78\frac{m}{s})\\p=991.32\frac{kg\cdot m}{s}$

From pythagoras theorem we know that:

$tan\theta=\frac{opposite}{adjacent}\\tan\theta=\frac{v_x}{v_y}\\\theta=tan^{-1}(\frac{v_x}{v_y})\\\theta=tan^{-1}(\frac{60,78\frac{m}{s}}{49\frac{m}{s}})\\\theta=51.12^\circ$

A man walks for 2 hours at a speed of 3m/s. How far does he travel?

Scorpion4ik [409]

First you get the data:

Velocity (v) = 3m/s
Distance (d) = ??
Time (t) = 2hr

Time conversion: hours to seconds:

1 hour = 3600 seconds

$\bf{2\not{h}*\left(\dfrac{3600 \ seg}{1\not{h}}\right)=7200 \ seg }$

We calculate the distance, using the formula:

$\bf{d=t*v }$

$\bf{d=3600\not{seg}*3\frac{m}{\not{m}} }$

$\bf{d=21600 \ m}$

Answer: I travel to 21600 meters.
