Asmall 19 kilogram canoe is floating downriver at a speed of 2 m/s. what is the canoe's kinetic energy?

Kinetic energy of the canoe is 38 Joules.

Explanation:

Given that,

Mass of canoe, m = 19 kilogram

Speed of flowing, v = 2 m/s

The kinetic energy of canoe is given due to its motion. Mathematically, it is given by :

k = 38 J

Hence, this is the required solution.

answer: its c lololo

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.
