Gauss' Law True/False Questions (Will pick best answer ASAP)?
1. If the radius of the spherical Gaussian Surface is varied, the flux through it also varies. False. As per Gauss's law, the total electric flux through any closed Gaussian surface only depends on the net enclosed charge and the electric permittivity constant. 2. Suppose (for this statement only), that q is moved from the origin but is still within both the surfaces. The flux through both surfaces remains unchanged. True. Again, the total electric flux through any closed Gaussian surface only depends on the net enclosed charge and the electric permittivity constant. 3. The Electric Flux through the spherical surface is less than that through the cubical surface. False. Again, the total electric flux through any closed Gaussian surface only depends on the net enclosed charge and the electric permittivity constant. 4. The area vector and the E-Field vector point in the same direction for all points on the cubical surface. False. Area vectors point outward from the surface. The electric field vector points directly away from the enclosed positive charge. Only in the case of a Gaussian surface aligned with the "spread" of an electric field is this true. 5. The E-Field at all points on the spherical surface is equal due to spherical symmetry. True. I cannot comment any more than "spherical symmetry"
Any people good at the Combined gas law?
Ziggle, thats what i got to so thanks. Scarlet, your equation is right but if multiply both sides by T1 and both sides by T2 iw works out to what i stated, its the same equation. And Thanks Ron i knew how to do the problem, I just wanted to know if I was right.
What are the pros and cons of axis bank ASAP account?
i want you to tell my story of ASAP account.to start with its not ASAP account. It took more than 15 days to get my account fully activated. lot of things done wrong, and bank branches dont care coz its a online account and they treat u like dog. And customer care always give fake or wrong info.whats wrong with ASAP account.No support or anything for this account, [ coz customer care is giving nonsense info just to pass u on to next agent, and they never update u on cases]Debit card fees, as the virtual card they provide as “free” is totally useless, coz no one accepts virtual debit card as a online payment method ( eg: google payments or paypal )Debit card will only be issued to your aadhar card address not your local address and they won't even take your address even if u give proof.Fake “ reward points” delighma, U wont get any points even if u its totally useless and a marketing gimmick.Non real time account sms. You wont get sms when money got debited or credited. its anytime in midnight or some other time0 interest till 10,000, even after 10,000 it ill be a fd in multiples of 500 inr and that’s not as straight as it seemsReally a total shitty bank,from standpoint of customer loyalty.But if you are looking for a zero bal account i highly recommend KOTAK 811 which is really awesome, and no bullshit as axis bank, its very good i opened in 3 min , agent came to my place to get biometric, my card came to my address in 2 days. rate of interest is for full amount. they don't have 24/7 customer care but they have AI and ML alogos which can take up all your needs without any agents, and only con would be they have very less branches and i personally hate going to bank. so win win.Good Luck
Should I get a divorce because of my mother-in-law?
You married each other. You did not marry each other's parents, and each set of parents did not marry the other set.The very first thing to do is to stop talking to people outside your marriage about matters that are inside your marriage (unless you are consulting a professional). The next thing to do is to shut down any conversation or commentary coming from outside the marriage about the inside. Your business is yours, not theirs, and "....is not a fit topic for discussion by anyone other than me and my husband, would you like some more tea?" "Thank you for your concern. We will have to make our own decision. Isn't this cake good." If you have manipulators in your life, and you're giving them exactly what they want - reaction, feedback, drama, attention, power, control - the place to start fixing it is with you. The only people in this marriage are you and your husband. Start acting like it, and you'll see things change.
How does Newton's Third Law of Motion work with catapults?
If we consider the case of a trebuchet on wheels, it becomes clear. When the trebuchet fires, it rolls back and forth. This motion is not in only one direction, because the arm of the trebuchet is travelling in an arc. At the beginning of the arc, it pushes the trebuchet forward, at the end of the arc, backwards. The motion is similar for an onager style catapult. The arc does not proceed past the vertical, so forward motion comes form the arm being stopped abruptly.
Planet X is observed to have a small moon. This moon is observed to orbit the planet once per month....?
Planet X is observed to have a small moon. This moon is observed to orbit the planet once per month at a distance of 15 Planet X diameters. What is the mass of Planet X in solar masses? [Hint: Use Newton's form of Kepler's Third Law: P2 is proportional to a3/M, where M is the mass of Planet X (assuming that the mass of the moon is negligible in comparison).] .... With units: a (semi-major axis): 2.9 AU (Planet X's diameter in AU) Planet X's diameter: 4.4 x 10^11 meters at Theta = 3.8 arcseconds I am getting soooo frustrated trying to figure this out just because I'm used with working with P in years, not months... Can someone PLEASE help me out ASAP with this?!?! ..
A ceiling fan rotating at constant speed is in equilibrium as net torque acting on it is zero. How is it zero?
Once again, before answering this question, I suggest reading the following to mince the basics of physics and drink it asap!University Physics by Zemansky - a standard book for the mechanics sectionConcepts of Physics by Resnick and Halliday - good for below UG, that means at the level of SATPhysics by Cutnell and Johnson - recommended for A Level Physics and IB PhysicsSo lets try to remove the dust from your understanding! I believe your question comes from a fact that you are not aware of and that is the following first question-What is torque?Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis, which we will call the pivot point, and will label 'O'. We will call the force 'F'. The distance from the pivot point to the point where the force acts is called the moment arm, and is denoted by 'r'. Note that this distance, 'r', is also a vector, and points from the axis of rotation to the point where the force acts. Take a look at the figure below.Torque is defined as followsSo r x F gives us the Torque. Essentially a cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, 'a' being the angle between r and F.The following animation gives you a nicer perception.GIF source: WikipediaAnswering your question - why net torque=Zero?There may be more than one force acting on an object, and each of these forces may act on different point on the object. Then, each force will cause a torque. The net torque is the sum of the individual torques.Rotational Equilibrium is analogous to translational equilibrium, where the sum of the forces are equal to zero. In rotational equilibrium, the sum of the torques is equal to zero. In other words, there is no net torque on the object.Lets illustrate this through pictures again and I will take the method of mathematical induction type. When will net torque not equal to zero? When the net force is zero. What will happen then? Well the body will rotate! Here is the illustrationThis kind of system is termed as in rotational equilibrium. So in shortIf net forces acting on the body is zero = TORQUE IS NOT ZERO and body will ROTATE.If net forces acting on the body is NOT zero = TORQUE IS ZERO and body will NOT ROTATE.
I need help with my physics homework please! :( asap. ?
the first part is that the truck driver is at fault. the truck was in motion and so was his lumber. when it crashed into the rolls, the lumber continued its motion unhindered (unlike the truck which was hindered when it hit the rolls), and landed on the other car. (first law) if the car had been moving, it would have come to a stop when it hit the truck. the lumber would stay inert while the truck might or might not have moved. that would most likely end up with the lumber staying on the truck (first law) or if the impact was especially hard, the truck would have been bumped ahead, the car bumped back (third law) and the lumber would have fallen on the ground where the truck used to be (first law). for the second part, he might collect the speed/acceleration and the mass of the truck/car to determine the force (2nd law).
What are Kepler's Laws?
Kepler’s First Law: “Each planet moves in an elliptical orbit with the sun at one focus of an ellipse”The distance from the orbital center to the focus at which the sun is situated is equivalent to [math]ea[/math] wherein [math]e[/math] = eccentricity of orbit and [math]a[/math] = length of semi-major axis.Kepler’s Second Law: A line from the sun to a given planet sweeps out equal areas in equal times.In a time interval [math]dt[/math], a sector of area [math]dA[/math] is subtended. The rate at which this sector is swept ([math]dA/dt[/math]) is known as the sector velocity. It is constant.[math]\dfrac {dA}{dt} = \dfrac {1}{2}r^2 \dfrac {d \theta}{dt}[/math]A few side notes:[math]\dfrac {dA}{dt} = \dfrac {1}{2}r v_0sin \theta[/math][math]mvrsin \theta = L[/math] (angular momentum)[math]\dfrac {dA}{dt} = \dfrac {1}{2m} (r [/math]x[math] mv) = \dfrac {L}{2m}[/math][math]\dfrac {dL}{dt} = \tau = r [/math]x[math] F ; [/math]this vector product = [math]0[/math] since central force vector F and position r lie along the same line.Since net torque = 0 , both magnitude and direction of angular momentum are conserved. r and v exist in the same plane, and thus planetary orbit is confined to one plane.Kepler’s 3rd Law: “The periods of the planets are proportional to the 3/2 power of the major axis lengths of their orbits”Proof of this law:[math]F_g= \dfrac {Gm_1m_s}{r^2}[/math][math]F_g [/math]is a radial force;[math] F_g = \dfrac {Gm_1m_s}{r^2} = ma_{rad} = m \dfrac {v^2}{r}[/math][math]v= \sqrt {\dfrac {Gm_s}{r}}[/math][math]v= \dfrac {2 \pi r}{T}[/math][math]T = \dfrac {2 \pi r}{v} = \dfrac {2 \pi r}{\sqrt{\dfrac{Gm_s}{r}}} = \dfrac {2 \pi r^{3/2}}{\sqrt{Gm_s}}[/math]r of an orbit is evidently a; the length of the major axis:[math]\dfrac {2 \pi a^{3/2}}{\sqrt{Gm_s}}[/math]
