I need some help in mechanics questions...?

Question

In which of the following units is acceleration expressed?

newtons

foot-pounds

kolograms

meters per second squared

the ability of a material to transfer heat or electrc current is callled?

insulation

porosity

conductivity

convention

Answer 1

meters per second squared

conductivity

Answer 2

Sound like physics questions actually. However:

1. newtons (n), foot-pounds (ft/lb), and kilograms (kg) are all units of measure dealing with weight or gravity.

Meters per second squared (m/s^2) or (m/s/s) deals with movement (acceleration).

2. insulation typicaly referes to the sheild or barrier around a conductor (like the plastic on a wire).

I am not sure what porosity is, unless you are talking about how pourus (amount of pores/holes/imperfections).

Conductivity is the measure of how well/poor a certain material transfers (conducts) hear or electric current.

Convection refers to hear transfer not electric current.

Answer 3

Accel -> m/s^2

Xfer -> conductivity
