Answer:

Scientific theories attempt to explain why certain events occur in the natural world.

Explanation:

A scientific theory is a set of concepts, abstractions of observable phenomena and quantifiable properties. It includes scientific laws, which express the relationships between the observations of the concepts and is verified in accordance with the scientific method.

Scientific theory is the most rigorous and complete form of knowledge. This definition is very different from the common use of the word "theory", which refers to something without support or an assumption.

<span>Scientific theories are tested and proven over time; they are then considered scientific laws.

Sometimes however, they are proven wrong, and so they do not become laws

Serga [27]

Answer:

Speed of river is 0.45 m/s

Speed of boat is 2.65 m/s

Explanation:

$v_r$ = Speed of river

$v_c$ = Speed of canoe

$v_r+v_c=2.8\ m/s$

$v_r-v_c=-1.9\ m/s$

Adding the equations we get

$2v_r=0.9\\\Rightarrow v_r=\frac{0.9}{2}\\\Rightarrow v_r=0.45\ m/s$

$0.42+v_c=2.8\ m/s\\\Rightarrow v_c=2.8-0.45\\\Rightarrow v_c=2.65\ m/s$

Speed of river is 0.45 m/s

Speed of boat is 2.65 m/s

The equation for distance is d = st. How far does a car go in 10 seconds at a<br> speed of 44 m/s?

nignag [31]

Answer:

44(speed) x 10(time) = 440(distance). So the answer is 440 meters.

sattari [20]

Answer:

2.0 s, 200 m

Explanation:

Time to hit the ground depends only on height. Since the plane is at the same height, the weight lands at the same time as before, 2.0 s.

Since the plane is going twice as fast, the weight will travel twice as far (ignoring air resistance). So it will travel a horizontal distance of 200 m.
