Answer:

The correct answer to the question: Which of the following hypotheses is both falsifiable and testable:____, would be, B: If all plants are watered at least once a day then they will all grow at least 1 cm a day.

Explanation:

In order to carry out research, hypothesis must be generated that will ask the questions necessary to find out information on different topics. However, not all questions, or statements will serve as a source for research, or lead to research. For this to happen, a researched must know that there are conditions to how to formulate a hypothesis; the first condition is that the hypothesis must be verifiable, or testable, which means, it can be proven. The second is, that the hypothesis must be falsifiable, or refutable, by research, and the third, the hypothesis must lead to results that can lead to further testing and reproduction. In this case, saying that all plants, when watered once a day at least, will grow a minimum of 1 cm a day cannot be used because it is based on a wrong assumption, given that all plants grow at different rates, and not all can be watered in the same way. This, in itself, from the outset, invalidates the hypothesis.

Sound and light are both found as _____, with a variety of ____. The sun, a source of light waves specifically, releases a type
Novosadov [1.4K]

Answer:

Waves; wavelength; electromagnetic energy; ultraviolet light.

Explanation:

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases.

Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

Hence, sound and light are both found as waves, with a variety of wavelength. The sun, a source of light waves specifically, releases a type of electromagnetic energy. It can be found as UVA or UVB types. These lights give off different levels of ultraviolet light, some of wich can be harmful.

Additionally, the ultraviolet spectrum is divided into three categories and these are; UVA, UVB and UVC.

A plane is landing. It started at 400m/s and ended up at 50m/s after 30 seconds. What is it's acceleration?
quester [9]

Give u = start velocity

        v = end velocity

v = u + at

50 = 400 + a*30

30a = -350

a = -116.67 m/s^{2}

**Why the accecleration is negative number**

Because displacement, velocity, and acceleration are VECTOR QUANTITIES.

Vector Quantity must have direction.
