Does any body know anything about Criminal justice??

Criminal justice is the delivery of justice to those who have committed crimes. The criminal justice system is a series of government agencies and institutions whose goal is to identify and catch the law-breakers and to inflict a form of punishment on them.

Yes. There are substantial numbers of attorneys and law school students and faculty members who know and understand quite a bit on the subject. There are even several incarcerated criminals who, through study and first-hand experience, have acquired extensive knowledge of that topic.

A 2-kg object is initially at the bottom of a long 50° inclined plane, and is beginning to slide up this inclined plane. The ini

Over [174]

Answer:

Explanation:

Given

mass of object $m=2 kg$

inclination $\theta =50^{\circ}$

$\mu _k=0.3$

$\mu _s=0.4$

initial velocity $u=3 m/s$

acceleration of block during upward motion

$a=g\sin \theta -\mu _kg\cos \theta$

$a=g(\sin 50-0.3\cos 50)$

$a=5.617 m/s^2$

using relation

$v^2-u^2=2a\cdot s$

where $s=distance\ moved$

$v=final\ velocity$

v=0 because block stopped after moving distance s

$0-(3)^2=2\cdot (-5.617)\cdot s$

$s=\frac{4.5}{5.617}$

$s=0.801$

If block stopped after s m then force acting on block is

$F=mg\sin \theta =$ friction force $f_r=\mu mg\cos \theta$

$F>f_r$ therefore block will slide back down to the bottom

Nonamiya [84]

Complete Question:

A deuteron (a nucleus that consists of one proton and one neutron) is accelerated through a 4.01 kV potential difference. b) How much kinetic energy does it gain? The mass of a proton is 1.67262 × 10−27 kg, the mass of a neutron 1.67493 × 10−27 kg and the charge on an electron −1.60218 × 10−19 C. Answer in units of J\

b) what is the speed?

Answer:

a) the kinetic energy gained = 6.42 * 10⁻¹⁶ J

b) the speed of the particle, v = 619328.3 m/s

Explanation:

q = 1.602 *10⁻¹⁹C

V = 4.01 kV = 4.01 * 10³ V

Work done by the deuteron = qV

Work done by the deuteron = 1.602 * 10⁻¹⁹ * 4.01 *10³

Work done = 6.42 * 10⁻¹⁶ J

Kinetic Energy gained = work done

Kinetic Energy gained by the deuteron = 6.42 * 10⁻¹⁶ J

B) The formula for Kinetic Energy is given by:

KE = 1/2 Mv²

Let the mass of the proton be m₁ = 1.67262 × 10⁻²⁷kg

Let the mass of the neutron be m₂ = 1.67493 × 10−27 kg

M = m₁ + m₂

KE = 1/2 ( m₁ + m₂)v²

Let v = speed of the deuteron

From part (a)

KE = 6.42 * 10⁻¹⁶ J

1/2 ( m₁ + m₂)v²= 6.42 * 10⁻¹⁶

0.5 * (1.67262 + 1.6749) *10⁻²⁷ * v² = 6.42 * 10⁻¹⁶

v = 619328.3 m/s
