A nation's nominal GDP is $1.5 trillion with an inflation rate of 5%. ∴ Real GDP is 30 trillion.
<u>Explanation:</u>
Key Terms
GDP deflator: A measure of the level of prices of all new, domestically produced, final goods and services in an economy. It is calculated by computing the ratio of nominal GDP to the real measure of GDP.
real GDP: A macroeconomic measure of the value of the economy’s output adjusted for price changes (inflation or deflation).
nominal GDP: A macroeconomic measure of the value of the economy’s output that is not adjusted for inflation.
GDP deflator( inflation rate = 5% ) =
![$\frac{\text { Nominal GDP }}{\text { Real GDP }} \times 100$](https://tex.z-dn.net/?f=%24%5Cfrac%7B%5Ctext%20%7B%20Nominal%20GDP%20%7D%7D%7B%5Ctext%20%7B%20Real%20GDP%20%7D%7D%20%5Ctimes%20100%24)
Inflation rate = ![\frac{1.5}{\text {Real } G D P} \times 100](https://tex.z-dn.net/?f=%5Cfrac%7B1.5%7D%7B%5Ctext%20%7BReal%20%7D%20G%20D%20P%7D%20%5Ctimes%20100)

∴ Real GDP is 30 trillion.
The average power produced by the rocket is the product of force exerted by the rocket and the velocity of the rocket.
<h3>Average power produced by the rocket</h3>
The average power produced by the rocket is calculated as follows;
P = FV
where;
- P is the average power
- F is the force exerted by the rocket
- V is the velocity of the rocket
Thus, the average power produced by the rocket is the product of force exerted by the rocket and the velocity of the rocket.

The answer is "iron fusion".
In fact, initially all stars burn hydrogen through nuclear fusion. As they run out of hydrogen, they start to burn the next heavier element, which is helium. The very massive stars continue this cycle, and when they run out of helium they start to burn the heavier elements until reaching iron. This element represents the end of the chain, because nuclear fusion of iron does not release energy, but it absorbs energy. This means that the star can't produce energy anymore and eventually it collapses.
Answer:
The total amount of energy that would have been released if the asteroid hit earth = The kinetic energy of the asteroid = 1.29 × 10¹⁵ J = 1.29 PetaJoules = 1.29 PJ
1 PJ = 10¹⁵ J
Explanation:
Kinetic energy = mv²/2
velocity of the asteroid is given as 7.8 km/s = 7800 m/s
To obtain the mass, we get it from the specific gravity and diameter information given.
Density = specific gravity × 1000 = 3 × 1000 = 3000 kg/m³
But density = mass/volume
So, mass = density × volume.
Taking the informed assumption that the asteroid is a sphere,
Volume = 4πr³/3
Diameter = 30 m, r = D/2 = 15 m
Volume = 4π(15)³/3 = 14137.2 m³
Mass of the asteroid = density × volume = 3000 × 14137.2 = 42411501 kg = 4.24 × 10⁷ kg
Kinetic energy of the asteroid = mv²/2 = (4.24 × 10⁷)(7800²)/2 = 1.29 × 10¹⁵ J
