Answer:These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.
Explanation:
The correct answer for the statement “All the scientific
theories used to explain the formation of the solar system are non-testable”. The
answers outdated, imaginative and unacceptable are wrong. These theories are
not proven and yet are not tested due to the complexity.
Answer:
Velocity, quantity that designates how fast and in what direction a point is moving.
Explanation:
<span>1. We can learn what types of organisms lived at what times and where they lived.
2. We can learn about when certain groups of animals evolved and what their ancestors were like.
3. We can learn how the continents drifted by comparing where fossil species have been found (for example, a species that was found in Africa and South America but couldn't cross an ocean would tell us that Africa and South America used to be connected.
4. We can learn about organisms that no longer exist, including what they ate and looked like, how big they were, and other traits.</span>
Answer:
16.5 m
Explanation:
The following data were obtained from the question:
Time (t) = 0.1 s
Speed of sound in air (v) = 330 m/s
Distance (X) =?
The Lenght (i.e distance) of the room can be obtained as follow:
v = 2X / t
330 = 2 × X / 0.1
Cross multiply
2 × X = 330 × 0.1
2 × X = 33
Divide both side by 2
X = 33/2
X = 16.5 m
Thus, the length of the room is 16.5 m.
