to increase the range of the water, isabellaplaces her thumb on the hose hole and partially covers it. assumingthat the flow remains steady, what fraction image for two children, ferdinand and isabella, are playing with a waterhose on a sunny summer day. isabella is holding of the cross-sectional area of the hose hole does shehave to cover to be able to spray her friend?
