B is negatively charged.

The electrons outnumber the protons, showing that its charge is negative.

However, on the rest of the hands, the number of electrons are either equal to (making the charge neutral) or less than (making the charge positive) the number of protons.

Hope this helped!

Galileo performed an experiment to measure the speed of light by timing how long it took light to travel from a lamp he was hold

Answer:

The time it takes light to cover 1.5 km was too short to be measured by Galileo's instruments.

Explanation:

The speed of light is $c=3*10^8m/s$ , which means the time it takes to cover a distance of 1.5 km (or 1,500m) will be

$t= \dfrac{1500m}{3*10^8m/s}$

$t= 0.000005s$

which is $\dfrac{1}{200000}$ of a second! This time delay could in no way be measured by Galileo considering the fact that he was using his heartbeat to measure time!
