Answer:
Newton's First Law of Motion
Explanation:
Newton’s first law of motion is when an object can’t move or change their speed without some type of force. Inertia is included since is caused by unbalanced force.
Answer:
Elctromagnetic waves can travel through empty space.
Explanation:
Waves that may pass through matter or empty space are known as electromagnetic waves. The electromagnetic field, like the other basic fields, penetrates the whole universe, including the region we refer to as empty space. There are no fields in space. The medium through which electromagnetic waves travel is called the electromagnetic field.
The summers in Michigan and Florida are similar because the plants in both regions end their periods of dormancy, trees start to grow buds, and plants begin to flower.
<h3>What are the effects of summer in plants in Michigan and Florida?</h3>
Summer is a period of increased sunshine and usually results in increased in plant growth and development.
Florida experienced an increased sunshine in summer periods.
Similarly, in Michigan, plants grow abundantly in summer time.
Therefore, the summers in Michigan and Florida are similar because the plants in both regions end their periods of dormancy, trees start to grow buds, and plants begin to flower.

<h3>
Answer:</h3>
B. It loses an electron and has an octet in its inner-most shell
<h3>
Explanation:</h3>
- Rubidium is a metal in the chemical family known as alkali metals.
- Metallic elements form ions known as cation by losing electron(s) from their outermost energy levels to attain an octet configuration.
- Rubidium has one electron in the outermost energy level, and thus, loses the electron to form a cation and forms an octet configuration.
- Like other alkali metals such as potassium and sodium, it forms a cation with a charge of + 1.
Answer:
D= 5 g/L
Explanation:
M= D x Vm
M is the molar mass = 112g/mol
D is the density
Vm is the molar volume whuch is 22.4L at STP
now substitute;
112 = D x 22.4
D= 112\22.4
D= 5 g/L
