Task. Read the text carefully. For each question, select the most appropriate answer: True, False, or Not Given and circle it. Kids' Ideas for Homes Children's drawings show houses with pointy triangular roofs, fluffy clouds, and weird windows. These pictures give us an idea into how children see homes and the world. Let's think about these drawings and imagine what these homes could look like in real life. In a recent project, children were asked to draw their idea of a "home of the future." The pictures they created showed homes with roofs shaped like rockets, pyramids, and even floating tree houses with magical stairs. Some of these homes even had solar power. Each drawing was with a 3-D model, which helped us see what these imaginative buildings could actually look like. Children's creativity is important for future challenges like safety, space travel, and using sustainable energy. These drawings show us how these questions important, even from a young mind's point of view. For example, 10-year-old Ameen wants homes that can float on clouds because they think traditional homes are old-fashioned. 5-year-old Charlie drew a mobile home with legs and arms so it can move anywhere. Ellis, a 7-year-old, dreams of an extra-safe home with strong materials like titanium bricks, bulletproof windows, and a steel roof. Ellis' design even includes metal clouds. 1. Children's drawings in the project included houses with triangular roofs and strange- shaped [1] windows.childrents Шелдон ​

Алюминиевый кубик массой m = 100 г разогрели, а затем поставили на лед, температура которого t2 = 0оС. Определите начальную температуру кубика, если максимальный объем льда, который сможет растаять, V = 50 см3. Удельная теплоемкость алюминия с = 900 Дж/(кг∙К), удельная теплота плавления льда λ=3,3∙105 Дж/кг, плотность льда ρ = 900 кг/м3.
