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.
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^2-2y)\,\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^2-2y) \,\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]

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.

Two question here please answer it correctly
40. Evaluate f (x2-2xy)dx +(x2y+3)dy around the boundary of the region defined by y2 = 8x and x = 2
(a) directly, (b) by using Green's theorem. Ans. 128/5
(TT.2)
41. Evaluate f (6xy - y2) dx + (3x2 --- 2xy) dy along the cycloid x = 6 - sin 6, y = 1 - cos 6.
(40) It looks like the line integral is
[tex]\displaystyle \int_C (x^2-2xy)\,\mathrm dx + (x^2y+3)\,\mathrm dy[/tex]
where C is the boundary of the region D,
[tex]D = \left\{(x,y) \mid \dfrac{y^2}8\le x\le2\text{ and }-4\le y\le4\right\}[/tex]
(a) To evaluate the line integral directly, split up C into two paths C₁ and C₂, parameterized by
• C₁ : x = t ²/8 and y = -t, where -4 ≤ t ≤ 4
(the y component is negative to make this path have a positive/counterclockwise orientation)
• C₂ : x = 2 and y = t, where -4 ≤ t ≤ 4
Then the line integral over C is the sum of the line integrals over C₁ and C₂ :
[tex]\displaystyle \int_C = \int_C \left(\left(x(t)^2-2x(t)y(t)\right)\dfrac{\mathrm dx}{\mathrm dt} + \left(x(t)^2y(t)-3\right)\dfrac{\mathrm dy}{\mathrm dt}\right)\,\mathrm dt \\\\ = \int_{-4}^4 \left(\left(\frac{t^3}4+\frac{t^4}{64}\right)\frac t4 - \left(3-\frac{t^5}{64}\right)\right)\,\mathrm dt + \int_{-4}^4 (4t+3)\,\mathrm dt \\\\ = \int_{-4}^4 \left(4t+\dfrac{t^4}{16}+\dfrac{5t^5}{256}\right)\,\mathrm dt = \boxed{\frac{128}5}[/tex]
(b) Using Green's theorem, we have
[tex]\displaystyle \int_C (x^2-2xy)\,\mathrm dx + (x^2+3)\,\mathrm dy = \iint_D \frac{\partial(x^2y+3)}{\partial x} - \frac{\partial(x^2-2xy)}{\partial y}\,\mathrm dx\,\mathrm dy \\\\ = \int_{-4}^4 \int_{y^2/8}^2 (2xy+2x)\,\mathrm dx\,\mathrm dy = \boxed{\frac{128}5}[/tex]

(41) I assume you meant to use θ in the parameterization, and not 6, so that C is parameterized by x = θ - sin(θ) and y = 1 - cos(θ). There's no range given for θ, so I'll just assume 0 ≤ θ ≤ π.
Then ... (for some reason, the math text won't render properly. I've attached the computation as an image)

(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

The term drum brake usually means a brake in which shoes press on the inner surface of the drum. When shoes press on the outside of the drum, it is usually called a clasp brake. Where the drum is pinched between two shoes, similar to a conventional disc brake, it is sometimes called a pinch drum brake, though such brakes are relatively rare. A related type called a band brake uses a flexible belt or "band" wrapping around the outside of a drum.

Who is an engineers?An engineer is a person who designs, builds, and maintains machinery and structures like bridges, railroads, and highways using scientific knowledge.
The word engineer, from which the term engineering is derived, was first used in 1390 to refer to "a constructor of military engines." The term engine'er literally means "one who operates an engine."
In this now-outdated meaning, the term "engine" refers to a military machine, or a mechanical device employed in battle.
An engineer is someone who practices engineering, and those who are qualified to do so may hold more official titles like "Designated Engineering Representative," "Professional Engineer," "Chartered Engineer," "Incorporated Engineer," "Ingenieur," or "European Engineer."
Teams of engineers design and deploy various goods utilizing predetermined procedures.
Thus, the correct option is A.

Explain how ABS system works using a friction
Answer:
ABS makes it so that the wheels of a car do not lock and slide when the driver slams on the brakes for an emergency stop.
ABS system senses when the wheels have locked and then pumps brake fluid in bursts using a friction
What is the ABS system?An anti-lock braking system (ABS) is defined as an automobile safety system that allows the wheels on a motor vehicle to manage tractive contact with the road surface according to driver inputs by braking, preventing the wheels from closing up (ceasing rotation), and avoiding uncontrolled skidding.There are three basic types of anti-lock braking systems namely four-channel/four-sensor, three-channel/three-sensor, and one-channel/one-sensor.It has 4 components namely a speed sensor, valves, ECU, and Hydraulic Control Unit.To learn more about the ABS system refer to:
