Q1. Magnetic Field and Force (20 points) As shown in Figure Q1, two magnetic fields exist in the regions enclosed by three boundaries, $l_1$, $l_2$, and $l_3$. Uniform magnetic field $B_1$=3.5×10$^{-6}$ T is directed out the page. Uniform magnetic field $B_2$ is directed into the page. The value of $B_2$ is unknown. Then, a proton has a mass equal to 1.67×10$^{-27}$ kg, has a charge of 1.8×10$^{-19}$ C, and moves into $B_1$ from point A. The velocity of the proton is vertically upward. The blue dotted line is the trajectory of the proton, which is composed of two quarter circles. The distance between $l_1$ and $l_2$ is d=5m. The distance from point A to $l_3$ is $d_4$= 2m. (1) Find the initial speed $v_0$ of the proton. (2) Find the magnitude of the magnetic field $B_2$. $B_1$=3.5×10$^{-6}$T d=5m $d_4$=2m

Pacific Islands and Australia British imperialism left an indelible mark on the history of Australia and New Zealand during the 18th and 19th centuries. This discussion explores the significant role these regions played in the broader narrative of colonial expansion. Australia: Penal Colony and Colonization Efforts In 1788, Britain declared Australia a penal colony, a pivotal move to alleviate the overcrowded prisons in the homeland. Establishment of Settlements: The colonies not only served as a solution to prison overcrowding but also laid the groundwork for broader colonization initiatives. Mid-19th Century Gold Discoveries: Australia's growth surged with the discovery of gold, attracting British settlers and shaping the region's economic landscape. New Zealand: Conflict, Annexation, and Treaty Relations New Zealand's colonization stemmed from conflicts between British settlers and the indigenous Maori people. 1841 Annexation: Britain officially annexed New Zealand, marking it as the last territory on Earth to be colonized. Treaties and Coexistence: The annexation was accompanied by treaties with the Maori, emphasizing partnership and protection of their rights. However, tensions and conflicts persisted as both communities navigated coexistence in the evolving colonial landscape. What was the initial purpose of Britain establishing settlements in Australia? to establish a utopian society to relieve overcrowded prisons to promote scientific research
