The development of fusion energy has not been successful so far because of the high temperatures needed for fusion to occur. It’
Nana76 [90]

Government  should continue to fund fusion energy research because:

  1. it potentially will produce large amounts of energy
  2. scientific research could discover more feasible methods of fusion energy production
  3. it is a very clean form of energy

<h3>What is fusion energy?</h3>

Fusion energy is the energy produced from fusion reactions.

Fusion reactions are a type of nuclear reaction in which small atomic nucleus are fused together to produce larger atomic nucleus with the release of large amounts of energy.

The Sun produces its energy from fusion reactions between hydrogen atoms to produce helium nucleus. This reaction takes place at very high temperatures.

It is important that the government continue to fund fusion energy research because:

  1. it potentially will produce large amounts of energy
  2. more scientific research could discover alternative cheaper methods of fusion
  3. it is a very clean form of energy

In conclusion, the continuous government funding will make it possible to finally discover cheaper and more feasible ways to produce fusion energy.

A 1.1-cm-diameter pipe widens to 2.34 cm, then narrows to 4.9 mm. Liquid flows through the first segment at a speed of 3.57 m/s.
ratelena [41]

Answer:

v2=0.79 m/s

Explanation:

equation of continuity: V1A1=V2A2

A=(pi)r^2

A1=(pi)(0.55cm)^2

A2=(pi)(1.17cm)^2

convert cm2->m2

A1= 0.95cm2=

A2= 4.3cm2=

(3.57 m/s)(0.000095 m^2)=(x m/s)(0.00043 m^2)

v2=0.79 m/s

hope this helped
