A 1Msun star in a closed binary system with a 2Msun star.
Systems in which the two stars are close to each other are called close binary star system.
The most massive stars have the shortest lifespans. The reason is that they have most fuel, they burn it so enormously that their lifetimes are very short. As a 1Msun star in a closed binary system with a 2Msun star becomes the massive star so it has the shortest life expectancy.
a. No, an isolated 1Msun star has not the shortest life expectancy.
b. No, a 1Msun star in a closed binary system with a 0.8Msun star has not the shortest life expectancy.
c. Yes, A 1Msun star in a closed binary system with a 2Msun star has the shortest life expectancy.

Answer:
c. Performs better on training data as the training process proceeds, while performing worse on a held-out test data
Explanation:
An over-fitted model is one that will perform best on training but would fail or do worse on a held-out test data.
Such models are optimum for a just a particular set of data but would grossly failed when extrapolated to some other data set not novel to it.
- Over-fitting a model implies that a model closely corresponds to a set of data but would not perform well with others.
- It is usually as a result of a model adapting the noise and other details of a particular data set and thereby incorporates it.
- This makes it difficult for the model to fit into another data set.
For those seeking for the answer, its a source of electrical energy.
In order to answer this, you can use this formula :
F = m.a
which means
a = F/m
a = 18N / 2kg
a = 9 N/kg or 9m/s2

Answer:
18 L
Explanation:
Use ideal gas law:
PV = nRT
Find initial number of moles, but first convert to units that match the gas constant units.
(200,000 Pa) (0.025 m³) = n (8.314 Pa m³ / mol / K) (25 + 273.15 K)
n = 2.017 mol
At the new pressure and temperature:
(250,000 Pa) V = (2.017 mol) (8.314 Pa m³ / mol / K) (0 + 273.15 K)
V = 0.018 m³
V = 18 L
