measures the skin's resistance or conductance to a small amount of current passed between two electrodes.

Acar travels 40m in 8 seconds find the car speed

Aforce of 40n applied at the end of length 4m and diameter 2.00mm process and extension of 0.24mm, calculate the stress on the wire, strain in the wire and the young modulus for the material of the wire

Can someone me with my physics questions? i need correct answers only!
