D= vt +.5at^2
since he started at rest, v (initial velocity) is 0
so d=.5at^2
d = .5 (6m/s^2) (4.1s)^2
then put that into a calculator.
The battery will be full still a 8v bc of no time comparison
Lower resistivity means higher conductivity: among these materials, the best conductor is silver, therefore it must be the material with lowest resistivity among those. We can also have a look at the value of resistivity of the different materials listed in the problem, to check our answer. The resistivities of the materials are the following:
Wood:

Salt water:

Silver:

Lead:

<span>We see that the material with lowest resistivity among those is silver, therefore the correct answer is silver.</span>
The answer is A. Polarized in a vertical plane
If positioned correctly, a polarized lenses can block all reflected light from horizontal surface such as road
Answer:
A and C are 180 deg out of phase (opposite points on a 360 deg wave)
