The phrase " Mars and Venus " is the following: moving one way, from west to east, then they stop and suddenly heading back to the west, and so on a few nights. moving one way, from west to east, then stop and stop. I'm going back to the west, and it's been a few times in the night. ♪ ♪ ” Specify the error in the display.

Try doing this:input_data = input('Что вы хотите сделать?\n(1)Запустить\n(2)Выйти ') if (input_data.isdigit()): command = int(input_data) if command == 1: pass elif command == 2: pass The error means the data are not number.

The physics diploma must be about physics. Programming may be the most rapid-convenience means of any calculation. Any normal professor of any science will not accept a diploma where this science is not devoted to a huge part of the work.

In my understanding, this sort of thing is being done very easily. There are two images up there. Before impact (leaf) and after impact (right). The reference speed vector is taken at random. I'll explain the point.The balls are moving somehow.The balls are hitting. The balls are deformed at the point of impact.The power of deformation is 100 per cent of the world's kinetic energy. The law on the preservation of the momentum and the law on energy conservation are working. With regard to impulse, it's vector value. That's why it can be divided into two dimensions. The OX axis is aligned with the line that connects the ball centers. OY tar OX. Vertical (OY) impulse on impact. It therefore remains unchanged. The horizontal constituents of impulse are simply exchanged. Total:V2OY = V2*OYV1OY = V1*OYV2OX = V1*OXV1OX = V2*OXAnd at 90 degrees, the balls will fly if one of the balls is stationary.

According to the commentaries, the problem is the id element. Some symbols are prohibited from being directly used in the selters and need to be screened.In this case:C:\\Down We need to screen at least the back-up tracks: C:\\\\Downthe element can then be obtained by means of a function document.getElementByIdas to maximise everything with the two-track, the current example will be: '#C\\3A \\\\\\\\Down' It's a great site that shows an example of what a screened sector would look like: https://mothereff.in/css-escapes#0C%3A%5C%5CDown or as an option, just remove such symbols.

Pensary that is as follows //Operacion float total = (float) (articulo * cantidad); float total1 = (float) (inicio - total); float porciento = (float) ((total1 / inicio) * 100); ObjectAnimator anim = ObjectAnimator.ofInt(pbarra, "progress", 0, (int) porciento);//En vez del 100 quiero traer el porciento de la operacion para sacar el porcentaje como le hago anim.setDuration(2000); anim.setInterpolator(new DecelerateInterpolator()); //iniciamos el progressbar anim.start(); String porcentaje = Float.toString(porciento); tvporcentaje.setText(porcentaje);

This method should be declared static:static bool cmd(int i1,int i2); // Предикат для сортировки I'll give you an index.sort(Vector.begin(),Vector.end(),&cmd); Explanation - non-statistical methods of the class are inaccurately obtained by an index to a copy of the class in the first paragraph. When you're trying to turn to the cmd method, he wants three parameters instead of two, that's a mistake. You can beat her with help. bind() But it's not your case.

This warning reports that the calling code has a reference to a variable object in the privacy of your facility. You received a reference to a variable object from outside (constructor and grid) or gave it to the ghetter. So a triggering code can suddenly change the condition of a part of your object and thus circumvent the checks you could conduct in the designer or the grid.For example, without using the grids, you can change your contents. Line:public static void main (String[] args) throws java.lang.Exception { Integer[] points = new Integer[] {1, 2, 3, 4}; Line line1 = new Line(points); System.out.println( "line1 = " + line1 ); // line1 = Line[pointsOnLine=[1, 2, 3, 4], valueMaxPoint=null, valueMinPoint=null] // ну не создавать же каждый раз новый массив points[0] = 5; points[3] = 7; Line line2 = new Line(points); System.out.println( "line2 = " + line2 ); // line2 = Line[pointsOnLine=[5, 2, 3, 7], valueMaxPoint=null, valueMinPoint=null] System.out.println( "line1 === line2 ? " + line1.equals(line2) ); // line1 === line2 ? true // Внезапно System.out.println( "line1 = " + line1 ); // line1 = Line[pointsOnLine=[5, 2, 3, 7], valueMaxPoint=null, valueMinPoint=null] } The best solution would be to use non-replaceable objects as parameters and values. If this is not possible, protective copies should be created (defensive copy). A copy must be deep, that is, if your mass contains variable objects, every object must also be copied. For a range of primitives or non-replaceable objects, suitable clone() or Arrays.copyOf♪The way you propose is not to solve the problem, since the reference to the mass is simply driven through the designer and the ghetter without change.See Effective Java Item 39.

You need to define the symbols. You must have for every object:x♪y - physical coordinates of the location of the facility. x+V*cos(theta) and y+V*sin(theta) or how you figure it out now. x+vx and y+vy (see below)v - absolute speed, in your example, it's like sqrt(5)theta (θ) - Speed vector anglepx♪ py - picsel coordinates you'll calculate, for example, Math.ceil(x) and Math.ceil(y) or by application of scale Math.ceil(x*scale)♪ ♪ ♪vx♪ vy - Speed projection v On axle x and y One and two of your examples. v and theta and vice versa.In formulae (not from the wikipedia but from the reference where the formula is codified in the wiki) the expressions are written as vx♪ vy for both facilities to be used v and theta♪ The hardest will be to determine the moment of impact.The collision is almost likely to be (probably 1) to be inconsistent with the timer tics. The location of the objects in the collision will need to be considered additional, i.e., the impact has not occurred now in the context of the impact counted. x by formula x+vx a little earlier, it's necessary for the right angle of the fig.As a consequence of the first, you must not miss the collision, and at great speeds, you will have objects flying through each other, i.e., you must be able to consider the impact over the previous time.For more than two objects, you'll have to check each one's collisions for what they've encountered before. Otherwise, one circle may run into the other two times in the past period without changing the trajectory (however it flew through one, pushing it, and flying in the same direction and pushing the second artifact).How to count the angle of the fig, I think you'll figure it out by drawing a rectangular triangle (hypotenuse - circumference centers, catheta - hypotenuse projection per axle x and u).In view of the above, I think there is a need for an analytical calculation of the system ' s, from collision to collision, i.e., to get rid of the discontinuity of time. And by the timer, just paint the whole system as of now.

Your question does not have a full answer as it is in a very broad sense. In short, you need a physics book, try to explain why.For example//Описание мира let World = { gravity: 1, //Кооф. гравитации в мире, которая влияет на скорость //Также например можно добавить другие факторы в мире //Например ветер, который может влиять на векторную скорость шара wind: { x: 1, y: 1 } }; //Описание шара let Ball = { //Вес шара weight: 1, ragius: 10, //Радиус шара //Векторная скорость шара speed: { x: 1, y: 1 }, //Упругость мячика elasticity: 1.5, //обычно это какой-то кофф. на который домножается скорость при коллизии объекта с другими friction: 1.5 //кооф. трения шарика - может понадобится при расчете движения шара по поверхности }; //Опишу например дерево let Tree = { elasticity: 1.5 //для минимальных простых расчетов будет достаточно значения упругости дерева. }So you have a ball that moves in a certain world, according to the formulas you need simulate water, vacuum, space, etc.) On the basis of ball weight, gravity, turf, vegetation, velocity and other input data, you can only begin to calculate the indicators you need. Until you gather such an introduction to the task, there's nothing you can expect, so no one here will give you a ready formula for your question. And if you need to do the calculations as close as possible, it will also need to be accompanied by data on the properties of materials and co-defendants. Maybe you should take a look at the ready physical moves like box2d.

if (gender[0] == 'W', 'w') So, according to the rules of language C, we're dealing with a comma operator, that is, a comparison is performed. gender[0] == 'W'after which the value returns wwhich, according to the rules of the same language, is regarded as true♪ Whatever the result of the comparison.if (gender[0] == 'W' || gender[0] == 'w') That's how it gets closer to what you wanted. ♪ ♪
