A person on a sled coasts down a hill and then goes over a slight rise with speed 2.7 m/s. The top of this rise can be modeled as a circle of radius 4.1 m
The sled and occupant have a combined mass of 110 kg. If the coefficient of kinetic friction between the snow and the sled is 0.10, what friction force is exerted on the sled by the snow as the sled goes over the top of the rise? What will be an ideal response?
Answer the following statement(s) true (T) or false (F)
Consider an infinite solenoid with a rectangular cross section instead of a circular cross section. 1. The solenoid’s magnetic field must everywhere still point parallel to the solenoid’s central axis. 2. The solenoid’s magnetic field must still be zero everywhere outside the solenoid. 3. The solenoid’s magnetic field in the solenoid’s hollow interior must still have a uniform magnitude ? 0 (NI/L), where N is the number of turns in length L and I is the current carried by each turn
