A 2.19 kg block initially at rest is pulled to the right along a horizontal surface by a constant,
horizontal force of 16.1 N. The coefficient of
kinetic friction is 0.145.
The acceleration of gravity is 9.8 m/s
2.
Find the speed of the block after it has
moved 3.35 m.
Answer in units of m/s.

State the right hand rule of the direction of magnetic field in a conductor carrying current

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?
