A. The fossils cam from the same organism
Hope this helps!
The fossils came from the same organism. This conclusion is most reasonable.
What is fossil?A fossil is an item that has survived in the Earth's crust as a remnant, impression, or trace of an extinct animal or plant. The main repository for knowledge regarding the evolution of life on Earth is the complex of information preserved in fossils found all across the world.
Fossils of dinosaurs discovered in Alberta, Canada. Only a small percentage of extinct species have been preserved as fossils, and often only those with a sturdy skeleton are capable of doing so. A calcareous skeleton or shell is present in the majority of major groups of invertebrate creatures (e.g., corals, mollusks, brachiopods, bryozoans). Other types have silicon dioxide or calcium phosphate shells (both of which are found in the bones of vertebrates).

The equation for centripetal force can be derived by substituting the equation for centripetal acceleration into Newton’s second law.
Please select the best answer from the choices provided
T
F
Answer:
True.
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
[tex] F = ma[/tex]
Centripetal acceleration is given by the formula;
[tex] Acceleration, a = \frac {v^{2}}{r}[/tex]
Where;
v is the velocity.
r is the radius.
The equation for centripetal force can be derived by substituting the equation for centripetal acceleration into Newton’s second law.
Let centripetal force be Fc
Fc = ma
Substituting the value of "a" into the above formula;
[tex] Fc = m \frac {v^{2}}{r} [/tex]
[tex] Fc = \frac {mv^{2}}{r} [/tex]

The same spring is stretched 5 m. What was the force?
Answer:
La fuerza del resorte es directamente proporcional a la extensión del resorte. En otras palabras, si jalas mucho de la masa, la fuerza será intensa; si jalas poco de la masa, la fuerza será débil.
Explanation:
1. A Zambeef delivery track travels 18 km north, 10 km east, and 16 km south. What is its final displacement from the origin?
Answer:
10.2 km
Explanation:
Displacement is the shortest distance from your original position after movement.
Now, the Zambeef delivery truck moves 18 km north and then 10 km east and then 16 km south.
This means that vertically the truck is 2km short of the 18 km he travelled north..
So we can find the displacement using pythagoras theorem..
Let d be the distance from the current position to the initial position.
Thus;
d² = 2² + 10²
d² = 4 + 100
d = √104
d ≈ 10.2 km
I have attached a diagram showing the direction of this displacement
How are particles behaving in solid vs gas when it comes to sound?
Answer:
Sound waves have to travel through solids, gases, and liquids. Sound waves vibrate through the air in matter. Molecules in solids are packed tightly. This allows sound to travel faster through a solid than gas.
On Earth, what can a divergent boundary
cause?
A. An iceberg
B. A plateau
C. A rift valley
Answer: C
Explanation:
Divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.
Why do other stars look much dimmer than the sun?
In some areas, hydroelectric power is not geographically appropriate and a different renewable energy source would be a better option. A conservation group is looking for renewable energy sources other than hydroelectric energy that could be used to generate electricity in grassland ecosystems, such as in the midwestern United States or in a savanna in Africa.
Required:
a. Propose a different renewable resource to use that would be a realistic solution to generating electricity without using fossil fuels or hydroelectric power in a grassland ecosystem.
b. Justify the solution proposed above by explaining a potential advantage of using a different renewable resource to generate electricity.
Answer:
a) wind power system, turbines powered, solar power system
b) the possibility of creating jobs for the local workforce and of maintaining the environment without damaging it.
Explanation:
In a grassland system it may not have great changes in height or mountain system where it is easy to represent a river, therefore a hydroelectric power system is not very feasible.
a) You can have several alternative energy systems.
* If there is a fairly constant air current, a wind power system could be implemented.
* If there is a river with an acceptable flow, a generation system can be implemented with turbines powered by the river flow.
* Another system is a solar power system
b) To select any of the possible systems proposed, the current and future energy requirements of the region must be analyzed.
The amount of energy that each proposal can supply
Analyze the installation costs and the economic benefits of a given system.
Study the possible problems for the maintenance of each system.
A great advantage of these systems is the possibility of creating jobs for the local workforce and of maintaining the environment without damaging it.
The most plausible renewable energy source in a grassland is wind energy.
Renewable energy refers to energy that is obtained from wind, water biomass or underground heat. All of these sources of energy are inexhaustible and hold great prospect to solving the current energy deficit is many parts of the world.
In grasslands, the most plausible renewable source of energy is wind. Winds are abundant in grasslands . It is more plausible than hydroelectric power because it does not create any adverse environmental impact. It is the cleanest energy source.

Which has more momentum: a 3 kg sledgehammer swung at 1.5 m/s OR a 4 kg sledgehammer swung at 0.9 m/s? SHOW YOUR WORK FOR BRAINLEST
Answer:
3kg sledgehammer swung at 1.5 m/s
Explanation:
Small Sledgehammer:

MASS×VELOCITY=MOMENTUM
3.0×1.5= 4.5 (momentum)
Large Sledgehammer:
Mass:4.0
Velocity:0.9
4.0×0.9=3.6 (momentum)
higher momentum is the smaller Sledgehammer.
Calculate the gravitational pull between the Earth and the Moon
