What are the basic structures in which objects are grouped together in space?

this can be a lot of things, depending on how much gravity they produce. if there is a lot of gravity they <em>could</em> create a galaxy, star, or planet. if there is still lots of gravity, but not as much they <em>could </em>create a comet, asteroid, or dwarf planet. it all depends. Bu it can also be to do with what you mean by basic structures, and what the objects are.

rock can create asteroids, planets and parts of galaxies, gas, dust, ice and other things may create the rest and contribute to the other things.

A beam of unpolarized light in air strikes a flat piece of glass at an angle of incidence of 54.2 degrees. If the reflected beam

Stels [109]

Answer:

correct option is B. 1.39

Explanation:

given data

angle of incidence (θ) = 54.2 degrees

to find out

index of refraction of the glass

solution

we know that here reflected beam is completely polarized

so angle of incidence = angle of polarized ....................1

for reflective index we apply here Brewster law that is

μ = tan(θ) ...............2

put here θ value we get

μ = tan(54.2)

μ = 1.386

so correct option is B. 1.39

I place an ice cube with a mass of 0.223 kg and a temperature of −35◦C is placed into an insulated aluminum container with a mas

Nadya [2.5K]

To solve this problem it is necessary to use the calorimetry principle. From the statement it asks about the remaining ice, that is, to the point where the final temperature is 0 ° C.

We will calculate the melted ice and in the end we will subtract the total initial mass to find out how much mass was left.

The amount of heat transferred is defined by

$Q = mc\Delta T$

Where,

m = mass

c = Specific heat

$\Delta T =$ Change in temperature

There are two states, the first is that of heat absorbed by that mass 'm' of melted ice and the second is that of heat absorbed by heat from -35 ° C until 0 ° C is reached.

Performing energy balance then we will have to

$Q_i-E_h = Q_m$
