im not sure about most of this but ill try to help
so there are three formulas you need to know first: the formula for rate distance and time.
to find distance:
distance = rate * time
to find time:
time = distance / rate
and to find rate (which is what we need)
rate = distance / time
now we just use our formula and plug in the numbers
rate = distance * time
rate = 160 / 2 = 80
so our rate is 80. thats all i know i have no idea about the rest but i always use these messurments. im sure you can google most of it to get other formulas and calculators though. sorry i couldnt help much! good luck :D
According to research, none of these men were executed for believing that Earth revolves around the sun. Nicolaus Copernicus was the first to believe in the heliocentric view of the current solar system, but he was not killed for that view, but he died of natural means. Galileo Galilei was punished because of the heliocentric view but was only put under house arrest, and not killed. Giordano Bruno was indeed burned at stake, but it was not for his view on heliocentrism.

Answer:
a) 
b) west end of the bar is positive.
Explanation:
Given:
- emf induced in the bar,
- length of the bar,
- velocity of the bar at the given instant,
(a)
The magnitude of the horizontal component of the Earth's magnetic field(B):
We know:
(b)
Using Fleming's left hand rule we determine that the current is flowing towards east end of the bar i.e. west end of the bar is positive.
