The cost of developing thermonuclear power with plasmabe defended because D. It can provide an inexpensive power source.
<h3>How did the
cost of developing t
hermonuclear power defended?</h3>
The cost of developing thermonuclear power defended becvause we can see in the paragraph how it was told that the generation of ths power can be donee through the understanding of the occurrence of plasmain nature,
It should be noted that this thermonuclear power with plasmabe posses the characteristics which make it to exist in the ionosphere, and it can be felt in the flames as well; as in the chemical and nuclearexplosions.
In conclusion the power can be seen as an inexpensive source power because the p[roduction of this power cn be found in most of the thing that can be found around us as discused above.
Therefore, option D is correct.

Answer:
16.87 m/s
Explanation:
To find the speed of the car at the top, when the normal force is equal the gravitational force, we just need to equate both forces:
is the centripetal acceleration in the loop:
So we have that:
So, using the gravity = 9.81 m/s^2 and the radius = 29 meters, we have:
The speed of the car is 16.87 m/s at the top.
Answer:
Explanation:
From the question we are told that:
Initial pipe length
Final pipe length
Generally the equation for Frequency f is mathematically given by
Where
And
V=speed of sound in air
Therefore
Answer:
They will speed up, and decrease in density.
Explanation:
This is because, when water is heated, the molecules will spread apart, and bounce off each other. It gives them more space, and they are less tight packed, so it can move around freely.
Answer:
142.296 Nm.
Explanation:
Torque: This is the force that tend to cause a body to rotate or twist. The S.I unit of torque is Nm.
From the question,
T = F×r.................... Equation 1
Where T = Torque, F = Force, r = radius of the circle.
Note: F is the weight of the bicyclist.
Then,
F = W = mg............... Equation 2
Substitute equation 2 into equation 1
T = mgr................... Equation 3
Given: m = 88 kg, g = 9.8 m/s², r = 0.33/2 m
T = 88(9.8)(0.33)/2
T = 142.296 Nm.
