It looks like the diagram is telling you that there is a net force of 8 N + 4 N = 12 N pointed to the right. By Newton's second law, the magnitude of the net force <em>F</em> is equal to the mass <em>m</em> times the acceleration <em>a</em> :
<em>F</em> = <em>m</em> <em>a</em>
12 N = (4 kg) <em>a</em>
<em>a</em> = (12 N) / (4 kg)
<em>a</em> = 3 m/s²
<span>A mountain is a type of constructive force. This is because the mountains are formed (or "constructed") through the convergence of land plates. When the two (or more) plates come together, they cause the land at the fault line to shift upward, leading to the formation of mountains.</span>

The correct answer is (b.) gets colder. The density of the ocean water increases when the water gets colder. Therefore, it is already concluded that the density of the water and its temperature is indirectly proportional since as the density increases, the temperature decreases.
Answer:
The answer is below
Explanation:
When a gallon is blown the air energy is saved as potential energy which is compressed inside the balloon. However, when the balloon is released without trying its neck, the air energy quickly turned to kinetic energy, in which the air energy keeps moving as the balloon float around the space.
Hence, in short, what happens in terms of energy when you blow up a balloon and release it without trying its neck is that the air energy moves from potential energy to kinetic energy.
