Do you think that the country that has the right to force vaccinations on the community?
Answer:
no
Explanation:
we all have the freedom to choose whether we want to have something injected in our bodies that we aren't sure about. This would be a violation of our constitutional right to force us to take the vaccine.
Work the previous problem for the line integral f (x2+y2)dx + 3xy2 dy.
Feel free to consult the details in my answer to 24438105 if you wish to compute the line integral directly. I don't see any specification of which method to use, so I'll do it the faster way.
By Green's theorem,
[tex]\displaystyle \int_C (x^2+y^2)\,\mathrm dx + 3xy^2\,\mathrm dy = \iint_D \frac{\partial(3xy^2)}{\partial x}  \frac{\partial(x^2+y^2)}{\partial y}\,\mathrm dx\,\mathrm dy \\\\ = \iint_D (3y^22y)\,\mathrm dx\,\mathrm dy[/tex]
Since D is a disk with radius 2 centered at the origin, consider converting to polar coordinates using x = r cos(t ) and y = r sin(t ). Then
[tex]D = \left\{(r,\theta) \mid 0\le r\le 2\text{ and }0\le t\le2\pi\right\}[/tex]
[tex]x^2+y^2 = r^2[/tex]
[tex]\mathrm dx\,\mathrm dy = r\,\mathrm dr\,\mathrm dt[/tex]
[tex]\implies \displaystyle \iint_D (3y^22y) \,\mathrm dx\,\mathrm dy = \int_0^{2\pi}\int_0^2 (3r^2\sin^2(t)2r\sin(t))r\,\mathrm dr\,\mathrm dt \\\\ = \int_0^{2\pi} \int_0^2 (3r^3\sin^2(t)2r^2\sin(t))\,\mathrm dr\,\mathrm dt \\\\ = \int_0^{2\pi} \left(12\sin^2(t)\frac{16}3\sin(t)\right)\,\mathrm dt = \boxed{12\pi}[/tex]
Which of the following defines context?
the ability to find new ways of thinking about a problem
the condition in which a problem exists
the study of the theoretical nature of an event
the problemsolving technique of an engineer
Answer:
The condition in which a problem exists
Explanation:
Context is the situation surrounding information, e.g. if you don't understand a word in a passge you can look for "context clues" where you use surrounding words to infer the meaning of the unknown one
Rt = R1 + R2 + R3
[tex] \frac{1}{rt} = \frac{1}{r1} + \frac{1}{r2} + \frac{1}{r3} [/tex]
If R1 = 4Ω , R2 = 6Ω and R3 = 8Ω (Ω= ohm)
Calculate: 4.1.1 Rt (series)
4.1.2 Rt (parallel)
Answer:
In series:
[tex] \frac{1}{r} = \frac{1}{r_{1} } + \frac{1}{r _{2} } + \frac{1}{r_{3} } [/tex]
[tex] \frac{1}{r} = \frac{1}{4} + \frac{1}{6} + \frac{1}{8} \\ \\ \frac{1}{r} = \frac{13}{24} \\ \\ r = \frac{24}{13} \\ { \underline{r = 1.85 \: Ω}}[/tex]
In parallel:
[tex]r = r _{1} + r _{2} + r _{3} \\ r = 4 + 6 + 8 \\ r = 18Ω[/tex]

Many vehicles use halogen light bulbs. What must you avoid when handling halogen bulbs?
Answer:
here
Explanation:
try not to touch the Glass on Halogen Light Bulbs, even when changing the bulb. This is because when you touch a Halogen Light Bulb, you leave behind a residue on the Light Bulb which can in time cause the bulb to heat up unevenly, and even cause the bulb to shatter as a result.
How does Brake system work
Answer:
To stop a car, the brakes have to get rid of that kinetic energy. They do so by using the force of friction to convert that kinetic energy into heat. This hydraulic system multiplies the force of your foot on the brake pedal into enough force to apply the brakes and make the car stop.
Express the following numbers in decimal:
(a) (11001.1011)
2
(b) (A3.C)
16
(c) (75.16)
8
(d) (ABCD)
16
(a)
11001.1011₂ = 1×2⁴ + 1×2³ + 1×2⁰ + 1×2 ⁻¹ + 1×2 ⁻³ + 1×2 ⁻⁴
… = 16 + 8 + 1 + 1/2 + 1/8 + 1/16
… = 411/16
(b) In base 16, we have A₁₆ = 10 and C₁₆ = 12, so
A3.C₁₆ = 10×16¹ + 3×16⁰ + 12×16 ⁻¹
… = 160 + 3 + 12/16
… = 2620/16 = 655/4
(c)
75.16₈ = 7×8¹ + 5×8⁰ + 1×8 ⁻¹ + 6×8 ⁻²
… = 56 + 5 + 1/8 + 6/64
… = 3918/64 = 1959/32
(d) B₁₆ = 11 and D₁₆ = 13, so
ABCD₁₆ = 10×16³ + 11×16² + 12×16¹ + 13×16⁰
… = 40960 + 2816 + 192 + 13
… = 43981

how is a electrical resistance similar to the diameter of a pipe of water
Answer:
The resistance of the flow of charges in an electric circuit (electrical resistance) is analogous to the frictional effect between water flow through a pipe and the pipe's surface
Explanation:
In comparison to its similarity to the diameter of the pipe affects the flow of water and acts a a factor affecting resistance so are there factors affecting electrical resistance.
in an electrical circuit:
the total length of the wire is to the length of a pipe of water
the crosssectional area of the wire is to the diameter of a pipe of water.
Thus, the cross sectional are affects the amount of electrical resistance. Wider wires have wider crosssectional area and vice versa. Also, water will flow (i.e. current) through a wider pipe (i.e. large diameter) at a faster rate than a narrow pipe (i.e. small diameter). This is due to the lower amount of resistance offered by the wider pipe.
in the same manner, the wider the wire, the lesser the electrical resistance to the flow of elsctric charge and vice versa for thiner wires.
The thermostat is the gauge on your dashboard for _____.
A. telling the temperature inside the cabin
B. telling the oil levels remaining
C. checking water levels
D. checking the engine's temperature
The thermostat is the gauge on your dashboard for checking the engine's temperature. The correct option is D.
What is a thermostat gauge?The temperature gauge in your car, which is often seen on the dashboard, is used to display the coolant temperature for your engine. You can use this indicator to determine whether the coolant in your engine is cold, normal, or hot.
Your car's temperature gauge is made to gauge the coolant temperature in your engine. This gauge will indicate whether the coolant in your engine is cold, normal, or overheated. It is a crucial dial that may be found on your car's dashboard.
The same thermostat generates signals, typically electrical, combined in a system that includes relays, valves, controllers, and other components whenever the temperature rises or falls below the desired level.
Therefore, the correct option is D. checking the engine's temperature.

Discuss in detail the following methods used to redistribute income and wealth in cash grants?
Answer:
Redistribution of income and wealth is the transfer of income and wealth (including physical property) from some individuals to others through a social mechanism such as taxation, welfare, public services, land reform, monetary policies, confiscation, divorce or tort law.
The term typically refers to redistribution on an economywide basis rather than between selected individuals.
Interpretations of the phrase vary, depending on personal perspectives, political ideologies and the selective use of statistics.
It is frequently heard in politics, usually referring to perceived redistribution from those who have more to those who have less. Occasionally, however, it is used to describe laws or policies that cause opposite redistribution that shift monetary burdens from lowincome earners to the wealthy.

The phrase is often coupled with the term class warfare, with highincome earners and the wealthy portrayed as victims of unfairness and discrimination.

Redistribution tax policy should not be confused with predistribution policies. "Predistribution" is the idea that the state should try to prevent inequalities from occurring in the first place rather than through the tax and benefits system once they have occurred. For example, a government predistribution policy might require employers to pay all employees a living wage, not just a minimum wage, as a "bottomup" response to widespread income inequalities or high poverty rates.
Many alternate taxation proposals have been floated without the political will to alter the status quo. One example is the proposed "Buffett Rule", which is a hybrid taxation model composed of opposing systems, intended to minimize the favoritism of the special interest tax design.
