Answer:
a) t = 1.47 h b) t = 1.32 h
Explanation:
a) In this problem the plane and the wind are in the same North-South direction, whereby the vector sum is reduced to the scalar sum (ordinary). Let's calculate the total speed
v = 
f - 
v = 585 -32.1
v = 552.9 km / h
We use the speed ratio in uniform motion
v = x / t
t = x / v
t = 815 /552.9
t = 1.47 h
b) We repeat the calculation, but this time the wind is going in the direction of the plane
v= f -
v 585 + 32.1
v = 617.1 km / h
t = 815 /617.1
t = 1.32 h
Biomass is a modern name for the ancient technology of burning plant or animal material for energy production, or in various industrial processes as raw substance for a range of products.

Answer:
b. scientific theory, hypothesis
Explanation:
Hypothesis is an idea which is claim about any happening and how things work. On the other hand Scientific theory is tested. if it is proven correct by all ways, it becomes a law.
SO our correct answer is:
A <u>scientific theory</u> has been tested and supported many times whereas a <u>hypothesis</u> is an idea about how things might work.
