With a total force of 20,000 newtons, an airplane has a mass of 1,200 kg. What is its acceleration?
swat32

Answer:

<h3>The answer is 16.67 m/s²</h3>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

m =  \frac{20000}{1200}  =  \frac{200}{12}  \\  = 16.66666...

We have the final answer as

<h3>16.67 m/s²</h3>

Hope this helps you

Write a summary discussing this experiment and the results. Use the following questions and topics to help guide the content of
blsea [12.9K]

Answer:

A hypothesis. In science, a hypothesis is an idea or explanation that you then test through study and experimentation. Outside science, a theory or guess can also be called a hypothesis. A hypothesis is something more than a wild guess but less than a well-established theory. My hypothesis was right because although it was n educated guess it was still correct

The viscosity value decreased with the increase of temperature. The effect caused by temperature in the range studied was more important in the low range of temperature, whereas at high temperature, the viscosity showed less variation.The studies carried out in the present work indicated that the effect of temperature upon the viscosity of Galician honeys was prominent, and it is necessary to take into account this variable when the operation temperature is under 25°C, since below this value a small variation in temperature produces high changes in the viscosity value. On the other hand, different models to fit experimental values of viscosity/temperature have been proved. The glass transition temperature was determined necessarily since several models include this parameter in the equation, because it provides important information related to the viscosity value. All the models show a good behaviour but the best results were obtained using the Arrhenius one.

Which describe the image formed by an object on the center of curvature? Check all that apply.
9966 [12]

The image formed by a concave  mirror with the object placed at the center of curvature is real inverted and formed at the center of curvature. Using the ray diagram a ray from the top of the object to the mirror through f then reflected parallel to the principal axis,then the ray through the center of curvature reflected through the same point both intersect at a plane through center curvature and perpendicular  to the principal axis. The point of intersection forms the top of the image and the center of curvature forms the bottom. Therefore, the correct choices are : real and inverted
