Which of these are scientific questions? Check all that apply. How will climate change affect forests? Which planet is the prett
Naddika [18.5K]

Answer:

The scientific questions here are:

<em>a) How will climate change affect forests</em>

<em>b) How did life on Earth begin</em>

<em>c) Why did dinosaurs go extinct</em>

Explanation:

Scientific question are logical quantifiable questions, whose answers can be measured. A good scientific question must have answers that can be tested by a carefully designed experiment or measurement. Some qualities like "prettiest" and "amazing" cannot be tested for nor are they measurable, and hence, they do not make a testable component of good scientific question.

A car is traveling at 10 m/s. 10 seconds later the car is traveling 40 m/s. What is the car’s acceleration?
ratelena [41]

Answer:

a = 3 m/s^2

Explanation:

Vi = 10 m/s

Vf = 40 m/s

t = 10 s

Plug those values into the following equation:

Vf = Vi + at

40 = 10 + 10a

---> a = 3 m/s^2

Two objects are made of the same material, but they have different masses and temperatures. If the objects are brought into ther
DIA [1.3K]

The smaller body will have greater temperature change.

<h3><u>Explanation</u>:</h3>

Temperature is defined as the degree of hotness or coldness of a body. The relationship of the temperature with heat is described as

Q =m c dT.

Where Q is the heat content

m is the mass of body

c is the specific heat of body

dT is the temperature change of body.

Here the bodies are made up of same substance, so specific heat is same. The mass of bigger body is M and smaller body is m.

So the temperature change of the body will be dependent on the mass of the body. Heat loss by one body will be equal to heat gained by the other.

So M dT1 = mdT2.

So, M/m = dT2 / dT1.

So the the smaller body will be suffering higher temperature change.
