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

krok68 [10]

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!

Hey, there!

Answer: It sinks more.

We know that the water of sea is salty in nature which increases the density of water in sea and donot let's ship sink but in condition of river water it doesn't have any effects of salty water as it doesn't contain salty water due to which it's density is no more than the densityof ship which let's it sink more than sea water.

Hope it helps...
