SVETLANKA909090 [29]

The way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.

Given an incomplete sentence related to hypothesis and astronomy.

We are required to complete the sentence.

A hypothesis is basically a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon.

Astronomy is basically the study of everything in the universe beyond Earth's atmosphere.

The statement can be completed by "do experiments and observations about the prediction of the hypothesis".

Hence the way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.

A(t)=(t−k)(t−3)(t−6)(t+3) Given that a(2)=0 , what is the absolute value of the product of the zeros of a?
Ugo [173]
So using a(2)=0 we can first solve for k by substituting t for 2
0 = (2-k)(2-3)(2-6)(2+3)
0 = (2-k)(-1)(-4)(5)
0 = (2-k)20
0 = 40 - 20k
-40 = -20k
k = 2

The next step would be to find all the 0s of a.
0 = (t-2)(t-3)(t-6)(t+3)
T = 2,3,6,-3

Then we find the product
2x3x6x-3 = -108

Since the problem asks for the absolute value, the answer is positive 108

Which of the following processes suggest that matter is made up of minute particles.
Tasya [4]

Answer:

the answer is evaporation

Explanation: Evaporation is the process by which a liquid transforms into vapor (a gas). When some material is in its liquid phase, its particles are really close together (but not as much as we would see in a metal). As the temperature of the liquid increases, also does the kinetic energy of the particles. This cause the particles in the water to move a lot faster, thus its oscillations are larger. This causes an increase in the volume of the material.
