If a riverbed fills with this flowing water that travels north with a speed of 1.0m/s what is the resultant velosity of a puffin who tries to swim east across the tidal bore with a speed of 4.0m/s

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

The charge on an electron is 1.60218 × 10−19 c and its mass is 9.10939 × 10−31 kg. how strong a magnetic field must be experienced by the electron if its path is a circle of radius 5.5 cm? answer in units of t.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
