Can somebody help with those 3 problems please

Answers

Answer:

first one is option A

second one option B

third is26 N

Explanation:

1.the law here is every action has an equal and opposite......

2. only unbalanced forces move objects from rest or of uniform motion

3.net force is the sum of forces ,if forces are in the same direction

hope this helps plz mark me brainliest

2) Option A.
Force is directly proportional to the mass. As the mass of the fuel deceases as the fuel is burnt, the force also decreases as force is directly proportional to mass, and as the force decreases, the acceleration decreases as acceleration is also directly proportional to the force, and the shuttle may eventually come to a stop due to the increasing deceleration. However, initially if the forces are kept balanced as the space shuttle and the gases exert an equal amount of force on each other in the directions opposite to each other, the object will keep on moving upwards in a constant velocity as the amount of force is also kept constant.


3) Option B.
The motion will definitely change when the forces acting on an object are unbalanced-it will start to move, accelerate or decelerate or change its direction in the direction of the net force. The object will not move at all or continue moving with the same velocity and in the same direction if the forces acting on it are balanced or zero.

4) When the forces are unbalanced and are acting on an object in the same direction, the net force will be found by finding the sum of those forces.
Net force=17+9=26 N.

I really, really hope this helps! And please mark it as brainliest.

B-are made out of organic material that stores the sun energy

C-form where there are frequent earthquakes and volcanic activity

D- are produced high in the mountains where temperatures are low

Answers

Answer:

maybe C i'm so sorry if this is wrong

Explanation:

Organic materials and silt build on top to produce fossil fuels. Heat and pressure transform organic materials into coal, petroleum, or natural gas. Therefore, option (A) is correct.

What are fossil fuels?

An extracted and burnt fossil fuel is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remnants of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels.

Because certain sedimentary rocks contain trapped fossil fuels, sedimentary rocks and fossil fuels are connected. As organic materials and silt build up on top over time, fossil fuels are created. The organic material undergoes a chemical shift under heat and pressure, turning it into coal, oil, or natural gas.

Answers

Answer:

Explanation:

The similarity in their embryos and embryonic development suggests that reptiles, birds, and mammals share the same ancestor.

Similarity in the structure and development of embryo is one of the evidences that is been used by scientists to support the theory of evolution of species. According to the theory of organic evolution, all organisms are on earth as a result of descent with modifications from common ancestors.

Reptiles, birds, and mammals are all vertebrates. They share some basic characteristics and are thought to have shared a common ancestor before each group took different adaptive channels leading to their  differences as they currently exist.

Answer:

the answers are a, c, and d

Explanation:

a makes sense because if you are a member of a population then the other members live in the same area as you

b doesn't make sense because even though you live in the same population as someone, it doesn't mean you'd have the same density

c makes sense because the definition of population is, "a group of individuals of the same species living and interbreeding within a given area."

d makes sense since in order to be considered a member of a population you have to be living

e doesn't make sense since everyone is a different size

Members of a population have in common -

A. They live in the same area.

C. They are the same species.
