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

pV=const.

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, d=\frac{m}{V})

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:

V = U + at

Explanation:

<u>Given the following data;</u>

Initial velocity = 0 (since the stone is starting from rest).

Final velocity = 32 m/s

Acceleration = g = 10 m/s²

Time = 3.2 seconds

To show that the speed of the stone when it hits the ground is 32 m/s, we would use the first equation of motion;

V = U + at

Where;

  • V is the final velocity.
  • U is the initial velocity.
  • a is the acceleration.
  • t is the time measured in seconds.

Substituting into the formula, we have;

32 = 0 + 10*3.2

32 = 0 + 32

32 = 32

<em>Proven: 32 m/s = 32 m/s</em>

Most geologic activity takes place at
Dmitrij [34]

Most of the geologic activity happens at the boundaries between tectonic plates where two plates meet. This activity occurs as plates interact, such as volcanoes, earthquakes, and mountain building. Geographies that form at a plate boundary are determine by the direction of plate motion and by the type of crust at the boundary. 

Moreover, plate boundaries has three types namely; divergent plate boundaries where the two plates move away from each other, then convergent plate boundaries, here the two plates move towards each other and lastly, transform plate boundaries, in which the two plates slip past each other.

Define equilibrium and explain first condition of equilibrium. Pease make it fast...
Semenov [28]

Answer:

First Condition of Equilibrium

For an object to be in equilibrium, it must be experiencing no acceleration. This means that both the net force and the net torque on the object must be zero. Here we will discuss the first condition, that of zero net force. ... Fnet=0 F net = 0.
