krok68 [10]

Answer:

0.67m/s²

Explanation:

Given parameters:

Mass of toy  = 1.2kg

Force applied = 0.8N

Unknown:

Acceleration   = ?

Solution:

According to newton's second law of motion;

      Force  = mass x acceleration

Now,

      Acceleration = \frac{Force}{mass}

     Acceleration  = \frac{0.8}{1.2}   = 0.67m/s²

Finish the sentence below with the word that makes the sentence true.
Keith_Richards [23]

Answer:

Animals must eat other plants or animals to obtain the <u>energy</u> stored in the food

Explanation:

One classification of living organisms, according to the way they obtain energy, is that of autotrophs and heterotrophs. The first group is represented by plants, which process their own nutrients from inorganic matter.

<u>Animals -heterotrophes- are unable to process their own nutrients</u>, so they must obtain them from other organisms, either plants or animals. External food sources provide them with nutrients, which contain the energy substrate needed to perform their vital functions.
