- The complexity of Earth is beyond the capabilities of computer simulations.
- Numerous assumptions that must be made by computer models have a big impact on the forecasts they produce.
- A computer model can incorporate historical climate data, but it is not possible to draw assumptions about future climates using this data in any way.
- A computer model cannot distinguish between anthropogenic climate change and natural climatic fluctuations.
<h3>How precise are temperature forecasts made by climate models?</h3>
The forecasting of global surface temperatures is one of the most significant results of climate models.
Scientists evaluate the effectiveness of their models by contrasting observations of the Earth's climate with predictions of future temperatures and "hindcasts" of past temperatures. Then, by comparing specific climate models and the average of all models to actual warming, scientists may determine whether temperature projections are accurate.
Researchers can have more faith that models can effectively predict future changes in the same factors if they successfully simulate the climate response in the past.

Answer:
P = 180 [w]
Explanation:
To solve this problem we must use ohm's law, which is defined by the following formula.
V = I*R & P = V*I
where:
V = voltage = 200[volts]
I = current [amp]
R = resistance [ohm]
P = power [watts]
Since the bulbs are connected in series, the powers should be summed
P = 60 + 60 + 60
P = 180 [watts]
Now we can calculate the current
I = 180/200
I = 0.9[amp]
Attached is an image where we see the three bulbs connected in series, in the circuit we see that the current is the same for all the elements connected to the circuit.
And the power is defined by P = V*I
we know that the voltage is equal to 200[V], therefore
P = 200*0.9
P = 180 [w]
Answer:
Explanation:
Stars form inside relatively dense concentrations of interstellar gas and dust known as molecular clouds. The deep cold also causes the gas to cluster to high densities. When the density reaches a certain degree, stars form. Since the regions are dense, they become opaque to visible light and are known as dark nebula.
Answer:
Explanation:
angular momentum of the putty about the point of rotation
= mvR where m is mass , v is velocity of the putty and R is perpendicular distance between line of velocity and point of rotation .
= .045 x 4.23 x 2/3 x .95 cos46
= .0837 units
moment of inertia of rod = ml² / 3 , m is mass of rod and l is length
= 2.95 x .95² / 3
I₁ = .8874 units
moment of inertia of rod + putty
I₁ + mr²
m is mass of putty and r is distance where it sticks
I₂ = .8874 + .045 x (2 x .95 / 3)²
I₂ = .905
Applying conservation of angular momentum
angular momentum of putty = final angular momentum of rod+ putty
.0837 = .905 ω
ω is final angular velocity of rod + putty
ω = .092 rad /s .
