Light-rail systems have been tried all over the country, and they've failed. Although the people who support them have noble int

entions, sadly, the system the city proposes is doomed to fail as well. People simply enjoy their cars too much to endure any inconvenience for the sake of the environment. And I don't blame them. As the owner of Jake's Used Cars and Trucks, I have seen the joy and freedom car ownership brings people. Americans will never abandon that feeling for the sake of being slightly better citizens. I believe it is far more responsible to purchase a high-quality car with good fuel efficiency. Building an entire light-rail system from the ground up, as the city proposes to do, will be more wasteful in the end if nobody uses it — not to mention that it will take years to build and cost taxpayers millions of dollars. I encourage all city residents to vote against the light-rail system on May 1. Which statement best describes the author's point of view? A. The author thinks Americans should be more environmentally responsible. B. The author wants citizens to visit his car dealership. C. The author is opposed to the light-rail project. D. The author would like the city to implement its project successfully.

Citizens should vote against the proposed claim.

ANSWER: C. The author is opposed to the light-rail project.

EXPLANATION: The author understands the mentality and the sentiments of Americans. He knows the fact very well that people would never compromise their comfort, joy and freedom to become a good citizen. The author thinks they can be rather advised to buy high quality cars with good fuel efficiency than using the light rail system. So, to avoid taxpayers' millions of dollars, he wants the citizens to vote against it.

Currently, the Sun is thought to be located in the galactic _____________ about ____________ the center of the galaxy.
Ede4ka [16]

Answer:

a. Disk, 28 thousand light-years from

Explanation:

Since, a galactic disc is a component of disc galaxies, for instance spiral galaxies and lenticular galaxies. It consists of a stellar component and a gaseous component.

Also, the Sun lies within the galactic disk or in other words it is thought to be located in the galactic disk,

The Sun is located about 26,000 light-years away from the centre of the galaxy.

∵ From the given options 28,000 is nearest to 26,000

Hence, the sun is about 28 thousand light-years from the centre of the galaxy.

i.e. OPTION 'a' would be correct.

The freezer compartment in a conventional refrigerator can be modeled as a rectangular cavity 0.3 m high and 0.25 m wide with a
Anon25 [30]

Answer:

Thickness of Styrofoam insulation is 0.02741 m.

Explanation:

Given that,

Height = 0.25 m

Depth = 0.5 m

Power = 400 W

Temperature = 33°C

We need to calculate the area of Styrofoam

Using formula of area

A=2(lb+bh+hl)

Put the value into the formula

A=2(0.3\times0.5+0.25\times0.5+0.5\times0.3)

A=0.85\ m^2

Inner surface temperature of freezer

T_{i}=-10°C=263\ K

Outer surface temperature of freezer

T_{o}=33+273=306\ K

We need to calculate the thickness of Styrofoam insulation

Using Fourier law,

q=\dfrac{kA}{L}(T_{o}-T_{i})

L=\dfrac{kA}{q}(T_{o}-T_{i})

Put the value into the formula

L=\dfrac{0.30\times0.85}{400}(306-263)

L=0.02741\ m

Hence, Thickness of Styrofoam insulation is 0.02741 m.

Compute the dot product of the vectors u and v​, and find the angle between the vectors. Bold v equals 7 Bold i minus Bold j and
OLga [1]

Answer:

\theta = 106.3 degree

Explanation:

As we know that

\vec w = -\hat i + 7\hat j

\vec v = 7\hat i - \hat j

also we know that

\vec v. \vec w = -14

it is given as

\vec v. \vec w = (-\hat i + 7\hat j).(7\hat i - \hat j)

\vec v. \vec w = - 7 - 7 = -14

also we can find the magnitude of two vectors as

|v| = \sqrt{(-1)^2 + (7)^2}

|v| = \sqrt{50}

similarly we have

|w| = \sqrt{(7^2) + (-1)^2}

|w| = \sqrt{50}

now we know the formula of dot product as

\vec v. \vec w = |v||w| cos\theta

-14 = (\sqrt{50})^2cos\theta

\theta = cos^{-1}(\frac{-14}{50})

\theta = 106.3 degree

What is the force of gravity for a 12 kg turkey?<br><br> Please help asap
pogonyaev

Answer: 117.6N

Explanation:

By the second Newton's law, we know that:

F = m*a

F = force

m = mass

a = acceleration

We know that in the surface of the Earth, the gravitational acceleration is g = 9.8m/s^2.

Then we just can input that acceleration in the above equation, and also replace m by 12kg, and find that the force due the gravity is:

F = 12kg*9.8m/s^2 = 117.6N
