5 m. How fast does it travel through the water?
Answer:
10m/s
Explanation:
Given parameters:
Frequency of wave = 2Hz
Wavelength = 5m
Unknown:
Speed of the wave = ?
Solution:
The speed of a wave is derived from the product of wavelength and frequency;
speed = frequency x wavelength
Insert the parameters and solve;
speed =2 x 5 = 10m/s

b. Hypothesees are guesses; theories are correct answers.
c. Hypotheses usually are relatively narrow in scope; theories have broad explanatory power.
d. Theories are proved true; hypotheses are often contradicted by experimental results.
Answer: c. Hypotheses usually are relatively narrow in scope; theories have broad explanatory power.
Explanation:
In scientific decipline, the hypothesis is a tentative statement which is produced by the method of prediction and assumption based on direct observation of the natural phenomena or event. It can be tested by using the experimental methodology.
Theory is a explaination for the cause of natural event or phenomena. This is based on the evidences obtained after experimental trials. A hypothesis can be used for generation of theory. A theory is more explanatory approach because of the details and evidences than hypothesis. Hence, c is the correct option.
The correct answer is True
Explanation:
In geography, the term "landform" refers to a natural shape or form that can be found on the surface of Earth such as mountains, hills or canyons. All of these are formed through different processes such as movement in tectonic plates. Additionally, these are considered as a physical feature of Earth as landforms define the shape and features of the Earth's surface and also influenced other physical phenomena such as weather or wind patterns. According to this, it is true landforms is a physical feature on Earth's surface.
