A small 21 kilogram canoe is floating downriver at a speed of 3 m/s. What is the canoe's kinetic energy?
astraxan [27]
The formula for finding the kinetic energy of an object is:
KE = 0.5MV^2,
Where:
M= Mass
V = Speed
From the information given above,
M = 21 kg
V = 3 m/s
KE = 0.5 * 21 * 9 = 94.5
Therefore, the canoe's kinetic energy is 94.5 J

Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide. Look at the chemical equation for this reaction:
kondaur [170]

Answer:

4 Fe + 3 O₂ → 2 Fe₂O₃

Explanation:

Let's start with the oxygen.

Reactants - 2

Products - 3

What number do 2 and 3 have in common? 6.

Put a 3 in the reactants and a 2 in the products to balance the oxygen.

Fe + 3 O₂ → 2 Fe₂O₃

Now let's look at the iron.

Reactants - 1

Products - 4

Put a 4 in the reactants to balance the iron.

4 Fe + 3 O₂ → 2 Fe₂O₃

The equation is balanced. Hope that helps.
