Answer:
B. tinkering, presenting, testing
Explanation:
In technological designs, some actions that are part of a system of methodical tests are grouped as technological process. Technological process is defined as the ordered procedure or steps to be followed in order to successfully accomplish a task (e.g project).
The project must have been created and refined i.e tinkered to ensure it gives an expected result or outcome i.e the project should give a solution to the problem that it was designed for. Which would undergo presentation and testing before it can be approved.
Answer: 
Explanation:
We are given the following formula:
(1)
Where:
is the amount of heat
is the mass of water
is the specific heat of water
is the variation in temperature, which in this case is 
Rewriting equation (1) with the known values at the right side, we will prove the result is 
:
(2)
This is the result
The world’s supply of fossil fuels will dwindle slowly until a replacement source is found that provides the same power.
bc some day we will actually run out of it and find sth that gives power
Answer:
a)θ=74.03° (N-E)
b)t=1.56 hr
Explanation:
Given that
Plane speed = 200 km/h
Wind speed = 55 km/h
Now from diagram
V is the resultant velocity of plane
V=192.28 km/h towards north
From triangle ABC
θ=74.03°
Given that
d=300 km
We know that
d = V x t
300 = 192.28 x t
t=1.56 hr
Answer: The origin might be from MARS
Explanation: Meteorites origin are either from Asteroid, Moon or Mars. Their origin is usually classified according to their age after using radioisotope dating. Meteorites that originate from Mars are between the age of 4.5 billion to 200 million years. Since the meteorite in question is only a billion years old, the origin would be from Mars.
