We will use the Cosine Law:
m D² = A² + B² - 2 AB cos D
∠D = 65° + 58° = 123°
m D² = 220² + 140² - 2 * 220 * 140 * cos 123°
m D² = 48,000 + 19,600 + 33,854.72
m D = 319.15 km
After that we will use the Sine Law:
340 / sin 123° = 220 / sin (theta)
sin (theta) = 0.578
∠(theta) = sin^(-1)0.578 = 35.3°
Answer:
The magnitude of the vector D is 319.15 km and points 35.3° south to east.
The difference between a solid and a gas is that the particles are more conjoined together in a solid, when in a gas the particles are more spread out.
Cuz their is two unpaired valency electrons in their elemental state or because they all have the same number of valency electrons

An object with volume greater than it mass. to account less density and thus it will float
The mechanism that is responsible for the formation of snowflakes is the nucleation of ice crystals.
<h3>What is a Snowflake?</h3>
This is defined as a piece of snow which falls from the sky as a result of an extremely cold climate condition and is common in the arctic regions of the world.
Snow flakes are formed when ice crystals stick together to form the flakes which usually has a dust or pollen being formed around the area being talked about.
This is also regarded as a type of precipitation such as rain etc and is therefore the most appropriate choice.
