A 2000-kg sailboat experiences an eastward force of 2000 N by the ocean tide and a wind force against its sails with magnitude o

BaLLatris [955]

Answer:

The force exerted by the ocean tide is directed to the right (east).

The force exerted by the wind is directed to the northwest (45° N of W).

We should separate the x- and y- components of the wind force, and evaluate each component separately.

$F_x = 6000\cos(\pi/4)(-\^{x})\\F_y = 6000\sin(\pi/4)(+\^{y})$

We denote the direction to the right as the positive direction, so the x-component of the wind force is in the negative direction.

The resultant force is as follows:

$F_R = [2000 - 4242.64](\^{x}) + [4242.64](\^{y})\\F_R = -2242.64\^{x} + 4242.64\^{y}$

The resultant acceleration can be found by Newton's Second Law:

$F = ma\\\\a_R = F_R/m = -1.12\^{x} + 2.12\^{y}$

The magnitude of the resultant acceleration is

$|a_R| = \sqrt{(1.12)^2 + (2.12)^2} = 2.4 ~m/s^2$

The process of converting energy produced by wind turbines into electricity is about 40 percent efficient. If the transport of e

ExtremeBDS [4]

Answer: 7.2%

Explanation:

Given

Efficiency of converting energy produced by wind into electricity is about $\eta_1=40\%$

Transport of electricity efficiency $\eta_2=90\%$

Fluorescent light bulb efficiency is $\eta_3=20\%$

Overall efficiency is the product of all the efficiencies i.e.

$\Rightarrow \eta=\eta_1\times \eta_2\times \eta_3\\\\\Rightarrow \eta=0.4\times 0.9\times 0.2\\\Rightarrow \eta=0.072\ \text{or}\ 7.2\%$

Therefore, the overall efficiency is 7.2%

Two gerbils run in place with a linear speed of 0.50 m/s on an exercise wheel that is shaped like a hoop. Find the angular momen

Brilliant_brown [7]

Answer:

$L = 0.018 kg m^2/s$

Explanation:

Angular speed and linear speed is related to each other as

$v = R\omega$

here we know that

$v = 0.50 m/s$

$R = 0.08 m$

now we have

$\omega = \frac{v}{R}$

$\omega = \frac{0.50}{0.08}$

$\omega = 6.25 rad/s$

Now we know that moment of inertia of the system is given as

$I = (2M + m)R^2 [tex][tex]I = (2\times 0.22 + 0.0045)(0.08)^2$

$I = 2.84 \times 10^{-3} kg m^2$

Now angular momentum of the system is given as

$L = I\omega$

$L = (2.84 \times 10^{-3})(6.25)$

$L = 0.018 kg m^2/s$
