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]

How does Brake system work
Answer:
The car brake system works in a few ways: Your foot pushes on the brake pedal and the force generated by your leg is amplified several times by mechanical leverage. ... Pressure is transmitted equally to all four brakes. The force creates friction between brake pads and disc brake rotors which is what stops your vehicle.

To calculate current you can use the following calculation
Answer:
It depends on the circuit. Many would answer with Ohm's law, but that is not accurate because Ohm's law is applicable only to a particular case:
Ohm's law I = U / R; where R is a constant linear resistance, U a voltage, I a current, and no other impedance is in the system.
Ohm's law allway applies to linear constant resistances, but there is much more to an electrical system than just plain resistances.
Besides linear constant resistances there are: inductances, couppled inductances, capacitances, non linear behaviour, voltage and current sources, radiation behaviour, etc.. They all play a role t
Explanation:
Calculating electrical current in D C circuit : I (Intensity of current) =E (electromotive force) / R (Resistance of circuit).(ohm’s law)
Calculating electrical current in A C circuit : Ohm’s law for Capacitive circuit : The current in a capacitive circuit is directly proportional to applied voltage and inversely proportional to the capacitive reactance. I = E/Xc.
If there is a resistance in series with the capacitor,then I = E/Z , Z is the total impedance of, To find Z , square root of R square + Xc square.
Calculating electrical current in A C circuit,: Ohm’s law for Inductive circuit :
I = E/ XL ; 0r square root of R square + XL square =Z impedance. I + E/Z .

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:

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.

Answer:
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.
