Explanation:
she ends up with a displacement of 5km north of her house and a distance of 3km
Answer:
B) more dense; change to a liquid or solid
Explanation:
When the pressure of a gas is increased, the average distance between the molecules decreases. In fact, if we assume that the temperature of the gas is kept constant, then we have

which means that the product between pressure and volume is constant: so, if the pressure increases, the volume decreases, and therefore the density of the gas increases (because density is inversely proportional to the volume,
)
Moreover, at very high pressure, the gas can turns into a liquid and eventually into a solid: in fact, as the average distance between the molecules decreases more and more, at some point they becomes so close to each other that the intermolecular forces start to be relevant, turning the gas into a liquid.
Answer:
Yes. Walking is controlled falling because you need to let go in order to move forward. If you never let your foot fall, your movements would be stilted and robotic. And according to medical engineers," When we walk normally we are constantly correcting tiny falls to keep ourselves stable."
Explanation:
W=mgh
W=(6)(9.8)(4)
W= 235.2J
