1. A little boy with a mass of 40. kg, is riding in a wagon pulled by his HUGE dog, Howard.
What is the acceleration of the wagon if the dog pulls with a force of 30. N? (Assume the
wagon rolls on a frictionless surface). (Ans: 0.75 m/s")

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

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) ! : )
