Answer 1

It is recommended to use dependency injection rather than directly using object Manager. Example: In your block file you can use following code to return product collection:

public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,
        array $data = []
    ) {

        $this->_productCollectionFactory = $productCollectionFactory;
        parent::__construct($context, $data);
    }
public function getProductCollection()
    {
        $collection = $this->_productCollectionFactory->create();
        return $collection;
    }
