(Combine colliding bouncing balls) The example in Section 20.8 displays multiple bouncing balls. Extend the example to detect collisions. Once two balls collide, remove the later ball that was added to the pane and add its radius to the other ball, as shown in Figure 20.17b. Use the Suspend button to suspend the animation, and the Resume button to resume the animation. Add a mouse-pressed handler that removes a ball when the mouse is pressed on the ball.

- Indicate a rotation code that would rotate the object on the left to obtain the view shown on the right. There may be more than one correct answer; this question will be graded manually. Type the rotation code using +/- and X/Y/Z. For example if the first rotation is positive around the z axis and the second rotation is negative around the y axis, type +Z Y. 2.arrow_forwardWrite code to draw the following picture.arrow_forward7.Do code complete"""You are given an n x n 2D mat representing an image.
