In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

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) ! : )
