The shape of JET experimental fusion reactor is the 'D-shaped' vacuum chamber.

<u>Explanation: </u>

JET, “Joint European Torus” is World's biggest magnetically compact plasma physics experiment, in Oxfordshire, UK. The tokamak design paved way to the future nuclear fusion grid energy.

JET was the first tokamaks designed to use this D-shaped chamber. The initial construction of this chamber was purely based on safety factor, but later it was noted that the system was built mechanically to reduce the net force across the chamber which forces the torus towards middle of major axis.

To support the forces, magnets around the chamber should be curved at top and bottom and less on inside to support the acting forces leads to oval shaped chamber. The D shape of the reactor has the dimension of about 2.5 meters in width and 4.2 meters in height with the total of 100 cubic meters of volume for the plasma.

Suppose the U.S. national debt is about $14 trillion. If payments were made at the rate of $3,500 per second, how many years wou
andreyandreev [35.5K]

Answer:

It will take 126.84 years to pay off the debt

Explanation:

Total debt = $14,000,000,000,000.00

Paid $3,500 per second

Number of seconds to pay off the debt will be:

14 ×10^12 /3500

Number of seconds = 4× 10^9 seconds

Converting seconds to year:

I second = 3.171 ×10^-8 calendar year

Therefore, number of years it will take to pay off $14 Trillion =( 4 ×10^9 ) × ( 3.171 × 10^-8)

Number of years = 126.84 years

A bicycle pump contains 20 cm3 of air at a pressure of 100 kPa. The air is then pumped in a tyre of volume 100 cm3. Calculate th
Natasha2012 [34]

Answer:

The pressure of the air in the tyre is 20 kPa

Explanation:

The parameters for the bicycle pump and tyre are;

The volume of air contained in the bicycle pump, V₁ = 20 cm³

The pressure of the air contained in the bicycle pump, P₁ = 100 kPa

The volume (available) of the tyre, where the air is pumped, V₂ = 100 cm³

Let P₂ represent the pressure in the tyre after the air is pumped

By Boyle's law, we have that at constant temperature, the volume of a given mass of gas is inversely proportional to its pressure;

Mathematically, Boyle's law gives the following equation;

P₁ × V₁ = P₂ × V₂

∴ P₂ = (P₁ × V₁)/V₂

Substituting the known values gives;

P₂ = (100 kPa × 20 cm³)/(100 cm³)

∴ P₂ = 100 kPa × 1/5 = 20 kPa

P₂ = 20 kPa

The pressure of the air in the tyre = P₂ = 20 kPa.

Why are high tides found simultaneously on opposite sides of earth?
dexar [7]

Explanation:

Why are high tides found simultaneously on opposite sides of Earth? The tidal bulges occur on both sides of Earth that are aligned with the tide-generating body. The ocean water experiencing high tide rotates around Earth on a 12-hour cycle.

WILL MARK BRAINLIEST. Which gas became part of Earth's atmosphere as a result of the evolution of life-forms?
Fittoniya [83]

Answer:

Earth's atmosphere was largely made up of nitrogen and carbon dioxide gases. After photosynthesizing organisms multiplied on Earth's surface and in the oceans, much of the carbon dioxide was replaced with oxygen.

Idk if this helps but plz mark brainliest if it does
