<h3><u>Answer;</u></h3>
Universe, galaxy, solar system, planet, moon
<h3><u>Explanation;</u></h3>
- <u>A galaxy</u>, such as our Milky Way Galaxy, is a collection of solar systems orbiting around a central core.
- <u>A solar system</u> consists of a star, normally the sun and all of its planets, asteroids, comets and other bodies.
- <u>A planet</u> is a nearly spherical body which is in orbit around the Sun. Planets are larger than moons.
- <u>Moons</u> are typically rocky bodies which are in orbit around planets.
Answer:
Resistance is a measure of the opposition to current flow in an electrical circuit.
Explanation:
Answer:
S = 27500J / 308.15molK
Explanation:
Entropy measures the degree of disorganization of a system. It is measured in the entropy change that is equal to the heat exchanged divided by the temperature at which the process occurs.
S2-S1 = Q / T
S = entropy
Q = heat = 27.5 kJ / mol * 1000J / 1KJ = 27500J / mol
T = temperature = 35 + 273.15 = 308.15K
units = J / molK
S = 27500J / 308.15molK
Answer:
a) θ₁ = 23.14 °
, b) θ₂ = 51.81 °
Explanation:
An address network is described by the expression
d sin θ = m λ
Where is the distance between lines, λ is the wavelength and m is the order of the spectrum
The distance between one lines, we can find used a rule of proportions
d = 1/600
d = 1.67 10⁻³ mm
d = 1-67 10⁻³ m
Let's calculate the angle
sin θ = m λ / d
θ = sin⁻¹ (m λ / d)
First order
θ₁ = sin⁻¹ (1 6.5628 10⁻⁷ / 1.67 10⁻⁶)
θ₁ = sin⁻¹ (3.93 10⁻¹)
θ₁ = 23.14 °
Second order
θ₂ = sin⁻¹ (2 6.5628 10⁻⁷ / 1.67 10⁻⁶)
θ₂ = sin⁻¹ (0.786)
θ₂ = 51.81 °
