Katie blows up a balloon and ties it so there is a fixed amount of air in the balloon. She wraps a piece of string around the widest part of the balloon, and measures it to find the size of the balloon. She has access to: A freezer  A warm cupboard A cold refrigerator A normal temperature classroom. Write a plan to collect results to answer the question: How does the temperature affect the size of a blown up balloon?

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )

Which is an advantage of subdividing science into different areas?
