Answer:

Answer A : Fusion followed by beta decay (electron emission)

Explanation:

Notice that you want the Atomic number to increase, that is the number of protons in a nucleus. So if all four cases given experience the same fusion of nuclei, the only one that net increases the number of protons in the last stage, is the reaction that undergoes a beta decay (with emission of an electron) thus leaving a positive imbalance of positive charge (proton generated in the beta decay of a neutron).

Therefore, answer A is the correct one.

On a spacecraft, two engines are turned on for 789 s at a moment when the velocity of the craft has x and y components of v0x =

ddd [48]

Answer:

Explanation:

Given

time for which spacecraft turned on is 789 s

$v_{0x}=5410 m/s$

$v_{0y}=8100 m/s$

$x=2.78\times 10^6 m$

$y=4.73\times 10^6 m$

we know $s=ut+\frac{at^2}{2}$

$2.78\times 10^6=5410\times 789+\frac{a_x(789)^2}{2}$

$2.78=4.268+a_x\times 0.622$

$a_x=-2.392 m/s^2$

For y component

$s=ut+\frac{at^2}{2}$

$4.73\times 10^6=8100\times 789+\frac{a_y(789)^2}{2}$

$4.73=6.39+a_y\times 0.622$

$a_y=-2.66 m/s^2$

A student sits at rest on a piano stool that can rotate without friction. The moment of inertia of the student-stool system is 4

bija089 [108]

Answer:

w = 0.55 rad / s

Explanation:

For this exercise let's use the conservation of angular momentum, let's write the moment in two moments

Initial

L₀ = r p + 0

L₀ = r mv

The first term is the angular momentum of the mass

Final

Lf = (I + m r²) w

Where I is the moment of inertia of the stool and the other term is the moment of inertia of the mass

L₀ = Lf

r mv = (I + m r²) w

w = m r v / (I + m r²)

Let's calculate

w = 2.0 0.45 3.0 / (4.5 + 2.0 0.45²)

w = 2.7 / 4.9

w = 0.55 rad / s
