Alfred Wegener believed that all of the continents were originally attached! By looking at the map, you can see that Africa and South America look like they were once joined. This 'super continent' was known as Pangaea. He also found fossils that proved his point.
Hope this helps :)
Answer:
1004.277N
Explanation:
Given that g = 9.817 ms^-2
If the angle between the cable and horizontal is 47°.
The angle between the cable and vertical is 90-47= 43°.
The weight of the beam is mg
The weight of the beam is
= 150*9.817
The weight of the beam is
= 1472.55N
magnitude of the vertical component of the force is mgsin(tita)
= 1472.55*sin43
= 1004.277N
Answer:
Explanation:
Given that
We know that
By using energy conservation
Heat lost by water = Heat gain by block
Therefore the specific heat of the block will be 0.501 kJ/kg.K
