Vlad [161]

Answer:

Integrated circuit (IC)

Explanation:

An integrated circuit ( IC ) is a semiconductor which contains multiple electronic components

interconnected to form a complete electronic function. Integrated circuits are the most essential part of all electronic products.

Modern integrated circuits contain as much as billions of circuit components such as transistors , diodes , resistors , and capacitors

A 0.0450 kg bullet is accelerated from rest to a speed of 425 m/s in a 2.25 kg rifle (which is inititally at rest). The pain of
Mrac [35]

Answer:

If the rifle is held loosely away from the shoulder, the recoil velocity will be of -8.5 m/s, and the kinetic energy the rifle gains will be 81.28 J.

Explanation:

By momentum conservation, <em>and given the bullit and the recoil are in a straight line</em>, the momentum analysis will be <em>unidimentional</em>. As the initial momentum is equal to zero (the masses are at rest), we have that the final momentum equals zero, so

0=P_{f}=m_{b} *v_{b}+m_{r}*v_{r}

now we clear v_{r} and use the given data to get that

v_{r}=-8.5\frac{m}{s}

<em>But we have to keep in mind that the bullit accelerate from rest to a speed of 425 m/s</em>, then <u>if the rifle were against the shoulder, the recoil velocity would be a fraction of the result obtained</u>, but, as the gun is a few centimeters away from the shoulder, it is assumed that the bullit get to its final velocity, so the kick of the gun, gets to its final velocity \bold{v_{r}} too.

Finally, using v_{r} we calculate the kinetic energy as

K=\frac{1}{2}m_{r}v_{r}^{2}=81.28J

Under which circumstances would protesters’ right to assembly most likely be protected?
ICE Princess25 [194]

Answer:

Explanation:

Mob violence is never protected. Organizers are always careful about not letting things get out of hand. Not D

That remark sort of applies to C as well. Property destruction is never protected.

B is something assemblies are allowed to do. So B.

A falls into the same category as C and D. You may not like the fact that he/she is doing something illegal, but you can't take away their privacy.
