For energy producing reactions they need Hydrogen atoms, heat, and pressure for the experiments.

<u>Explanation:</u>

The initial step of the Hydrogen combination process: a core of Deuterium (2H) is shaped from two protons with the discharge of an antielectron and a neutrino. In the fundamental Hydrogen combination cycle, four Hydrogen cores (protons) meet up to make a Helium core.

An atomic combination response is characterized as the response wherein at least two lighter cores consolidate together to shape heavier cores with the arrival of high measures of vitality.

Combination can possibly give the sort of baseload vitality expected to give power to our urban communities and our enterprises. Maintainability: Fusion powers are generally accessible and almost limitless.

How roofs are lifted off building in tornado?
bekas [8.4K]

Explanation:

As a tornado or other storm system passes over a building, low pressure can tug a roof upward. When those forces surpass the force exerted by the weight of the roof, the structure flies up and is swept away by wind currents..

A spherical bowling ball with mass m = 4.1 kg and radius R = 0.117 m is thrown down the lane with an initial speed of v = 8.9 m/
weqwewe [10]

Answer:Given mass = 4.1kg

Radius = 0.0117m

Velocity V = 8.4m/s

Coefficient of friction = 0.25

Explanation: Below is an attached solution to the problem stated above.

1. The angular acceleration is equal to 524rad/s^2

2. The linear acceleration is equal to 2.45m/s^2

3.the time it takes the ball to begin rolling = 0.98s

4. The distance the ball slides before it begins to roll = 7.05m

Azurite is a mineral that contains 55.1% of copper. How many meter of copper wire with diameter of 0.0113 in can be produced fro
soldier1979 [14.2K]

Answer:

1402.73 m

Explanation:

Mass of Azurite=3.25 lb

Percent of copper in AZurite mineral=55.1%

Diameter of  copper wire,d=0.0113  in

Radius of copper wire=r=\frac{d}{2}=\frac{0.0113}{2}=0.00565 in=\frac{565}{100000}=\frac{565}{100}\times \frac{1}{1000}=5.65\times 10^{-3}in

\frac{1}{1000}=10^{-3}

Density  of copper=\rho=8.96g/cm^3

1 lb=454 g

3.25 lb=3.25\times 454=1475.5 g

Mass of Azurite=1475.5 g

Mass of copper=\frac{55.1}{100}\times 1475.5=813 g

Density=\frac{Mass}{volume}

Using the formula

8.96=\frac{813}{volume\;of\;copper}

Volume of copper wire=\frac{813}{8.96}=90.7cm^3

Radius of copper wire=5.65\times 10^{-3}\times 2.54=14.35\times 10^{-3} cm

1 in=2.54 cm

Volume of copper wire=\pi r^2 h

\pi=3.14

Using the formula

90.7=3.14\times (14.35\times 10^{-3})^2\times h

h=\frac{90.7}{3.14\times (14.35\times 10^{-3})^2}

h=140273 cm

1 m=100 cm

h=\frac{140273}{100}=1402.73 m

Hence, the length of copper wire required=1402.73 m
