Answer:
1 true, 2 true, 3 false, 4 false and 5 true
Explanation:
The magnetic field lines are used to graphically represent the magnetic field,
1 true. Because the field line is a graphic representation of the magnetic field
2 true leave one pole and reach another, there are no magnetic monopoles
3 false. The density of the lines gives an idea of the strength of the field, they are dense where the field is greater
4 false. The magnetic force is perpendicular to the field and therefore to the field lines
5 true. With the same experimental conditions, each field gives a unique force, if the lines cross different fields they would give the same force.
Longitude was. Determining longitude requires knowing the exact time of day, which was difficult prior to modern clocks. The source book below tells the story of Englishman John Harrison's life-long pursuit of building a reliable clock and its importance to navigation.

Answer:b
Explanation:
Given
Woman earn 50% more than her husband
Total sum of their money is ![=\$ 2500](https://tex.z-dn.net/?f=%3D%5C%24%202500)
Suppose man earns ![\$ P](https://tex.z-dn.net/?f=%5C%24%20P)
so women earns ![P+0.5 P=P(1+0.5)=1.5 P](https://tex.z-dn.net/?f=P%2B0.5%20P%3DP%281%2B0.5%29%3D1.5%20P)
Sum of their money is
![P+1.5 P=2500](https://tex.z-dn.net/?f=P%2B1.5%20P%3D2500)
Women earns
The experiments that claimed to demonstrate cold fusion were found
to have been faulty by others who reviewed them. Also, nobody else
was
able to reproduce the finding in other laboratories. In the world
of
Science, this pretty much says that the initial claims were unfounded.
