Answer:
The theory is supported by all the available observations and data.
Explanation: The scientific community will accept a theory when a sufficient body of evidence supports it. This includes experiments that refute other potential theories. Experiments should also be carried out that attempt to disprove the theory but cannot.
It should not matter who proposed the theory or who supports it, and instead should entirely be based on the quality and abundance of data supporting it.
Hope this helps!

Answer:

Explanation:
Force can be found by multiplying the mass by the acceleration.

The mass of the roller coaster is 2000 kilograms and the acceleration is 2 meters per second squared.

Substitute the values into the formula.

Multiply.

- 1 kg*m/s² is equal to 1 N
- Therefore our answer of 4000 kg*m/s² is equal to 4000 Newtons

The net force acting on the roller coaster is <u>4000 Newtons.</u>
Since the Earth is almost spherical in shape, we are actually to find first the volume of the spherical segment at a depth of 1,000 m. The radius of the Earth is 6,371,000 meters. The volume of a spherical segment is:
V = 1/3*πh²(3r - h)
Substituting the values and making sure the units is in mm,
V = 1/3*π(1000 m * 1000 mm/1 m)²[3(6,371,000 m * 1000 mm/1 m) - (1000 m * 1000 mm/1 m)]
V = 2×10²² mm³
Thus, the total amount of bacteria is:
2×10²² mm³ * 100 bacteria/1 mm³ = 2×10²⁴ bacteria
