Answer:

80 angle of reflection!

Explanation:

Because it is a flat, smooth surface it will reflect like that of a normal plane mirror, so the angle of reflection will be equal to that of the angle of incidence!

Hope this helps you understands!

Which BEST describes the physical properties of the Earth’s core?
Sonja [21]

C) a solid lower part and a liquid upper part

Explanation:

The physical nature of the earth's core is made up of a solid lower part and a liquid upper part.

The core is the innermost part of the earth and it is made up of metallic minerals.

  • It has the highest temperature and pressure of all the layers of the earth.
  • The core is divided into two. Outer and inner core.
  • Outer core is made up of molten metallic minerals. It is the layer where the earth geomagnetic field originates.
  • The inner core is solid metallic ball.
  • Evidence from seismic waves has furnished geoscientists with this knowledge.

Imagine an alternate universe where all of the quantum number rules were identical to ours except m_{s} had three allowed values
marishachu [46]

Answer:

so in a given orbital there can be 3 electrons.

Explanation:

The Pauli exclusion principle states that all the quantum numbers of an electron cannot be equal, if the spatial part of the wave function is the same, the spin part of the wave function determines how many electrons fit in each orbital.

In the case of having two values, two electrons change. In the case of three allowed values, one electron fits for each value, so in a given orbital there can be 3 electrons.

Scientists have concluded that Earth is at risk of future impacts with meteoroids. What are some criteria that engineers conside
Aleksandr [31]
Answer:
Explain step by step
Explanation:
Collisions with asteroids, comets and other stuff from space have been responsible for huge landmarks in our planet’s history: global shifts in climate, the creation of our moon, the reshuffling of our deepest geology, and the extinction of species.

Asteroid threats pop up in the news every now and then, but the buzz tends to fizzle away as the projectiles pass us by. Other times, as with the 2013 Chelyabinsk meteor in Russia, we don’t know they’re here until they’re here.
Perhaps most useful to remember is that when near-Earth objects (including asteroids, comets and meteoroids) enter the atmosphere, they’re called meteors; and if there’s anything left when they hit the ground, the resulting object is called a meteorite. We tend to focus on asteroids when talking about potential collisions, because they’re more likely to hit us than other stuff like comets, but still big enough to pose a threat.
