You want to wind a solenoid that is 3.5 cm in diameter, is 14 cm long, and will have a magnetic field of 0.0250 T when a current of 3.0 A is in the wire that makes up the solenoid. 1) What total length of wire do you need

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

Explain why you think this diagram shows what happened to the carbon in the biodome.

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) ! : )
