Suppose three neutrons are released when an atom in a sample of fissionable nuclei undergoes fission. Each of these neutrons has

Eddi Din [679]

Answer:

13 nuclei

Explanation:

From the question, the fission of one nucleus produces three neutrons which causes more nuclei to undergo fission.

This implies that, after the first fission, three neutrons cause three nuclei to undergo fission. The three nuclei that underwent fission produces nine neutrons which causes the fission of nine nuclei.

All together we the number of nuclei that underwent fission as;

1 + 3 + 9 = 13 nuclei.

A uniform cylinder of mass 4.3 kg and radius 0.4 m rolls down a ramp inclined at an angle 0.15 radians to the horizontal. what i

tester [92]

The cylinder's acceleration is

$a=\frac{gsin}{1+\frac{I}{mrL} }$

$= 2g\frac{sin}{3}$ θ

$= \frac{2(9.8) sin (0.15 rad)}{3} \\=0.9763 \frac{m}{sec r}$

<h3>How do you determine a cylinder's acceleration?</h3>

The cylinder's complete radius, $R$ , from the center marks the contact point, therefore the torque created by friction is given by $fR = I\alpha$ , where is the rotating acceleration. This rotational acceleration's corresponding linear acceleration, $\alpha$ , is equal to $R$ . The cylinder, which has its mass concentrated in its center, triumphs in the competition, followed by the disc and the hoop, with their respective final velocities being roughly $1.4:1.2:1$ . We can also see that our findings are unaffected by the cylinders' masses.
