A scientist heats an unknown substance in a closed system. The graph shows the change in temperature over time.

Physics
1 answer:
Vinil7 [7]3 years ago
8 0

Answer:

C

Explanation:

When a substance is changing state, the heat supplied does not result in a rise in temperature. This is why, the heat supplied during change of state is referred to as 'latent heat'.

Latent heat is a heat that causes a change of state without a corresponding rise in temperature. During this time, the intermolecular bonds in the substance are broken.

Change of state will occur as regions in which there is no change in temperature with time such as point D on the graph.

If electromagnetic radiation acted like particles in the double-slit experiment, what would be observed? (1 point)
ludmilkaskok [199]

If electromagnetic radiation acted like particles in the double-slit experiment, we would observe one bright band would appear in the center of the screen.

<h3>Bahavior of particles in double-slit experiment</h3>

In a double-slit experiment, single particles, such as photons, pass one at a time through a screen containing two slits.

The photons behave like wave and the constructive interfernce of the waves of these photons will generate a high amplitude wave seen as a bright band in the center of the screen.

Thus, if electromagnetic radiation acted like particles in the double-slit experiment, we would observe one bright band would appear in the center of the screen.

Find the force necessary to pull a 6 kg object 3 m/s2
mars1129 [50]

Answer:

<h2>18 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 6 × 3

We have the final answer as

<h3>18 N</h3>

Hope this helps you

If the designers of submarines do not appropriately account for hydrostatic pressure,
andre [41]

Answer:

A) the pressure could crush the submarine

Explanation:

  • The submarines are mainly used for defense purposes.
  • In world war 1 and 2 the submarines played a vital role in the war.
  • The submarines work according to the principle of buoyancy.
  • According to this principle, when seawater is filled inside the tank in a required amount, the submarines sink.
  • When the seawater is expelled, the submarine rises to above the sea.
  • Most of the time, it dives deep into the sea, the hydrostatic pressure should be taken into account.
  • If the hydrostatic pressure is not considered, the pressure could crush the submarine.
