1. Which object size resulted in the production of the greatest impact force? 2. What is your evidence? 3. How does adding speed to the falling object change its impact force? 4. What is your evidence from the lab or your personal experience? If you are using a personal experience, please describe that experience and how it supports your claim. 5. It is widely believed now, based on indirect evidence, that an asteroid led to the mass extinction of dinosaurs here on Earth about 66 million years ago. Describe how it is possible for that particular asteroid to cause so much devastation when our plant is bombarded with space rocks every day

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
