Under the Florida  Statutes Annotated 316.1932 and 775.082,

" The administration of a urine test does not preclude the administration of any other type of test. The person shall be told his or her failure to submit to any lawful test of his  or her urine will result in the suspension of that person's privilege to operate a motor vehicle  for a period of  1 year for the first refusal, or for a period of 18 months if the driving privilege of such a person has been previously suspended as a result of a refusal to submit to such a test or tests..."

Rubidium forms the positive ion Rb+. Does this ion have more or fewer electrons than the neutral atom?
ohaa [14]

Answer:

The ion has fewer electrons

Explanation:

As Rubidium forms a positive ion Rb⁺ the number of electrons becomes fewer for the atom.

  • A positive charge on an ion indicates that the number of protons for the atom is greater than the number of electrons.
  • This leaves a net positive charge on the atom.
  • For a negatively charged ion, the number of electrons is more than the number of protons because they have gained additional electrons.
  • In a neutral atom, the number of protons and electrons are the same.

A 0.50 kg object is attached to a spring with force constant 157 N/m so that the object is allowed to move on a horizontal frict
Genrish500 [490]

Explanation:

We have,

Mass of an object is 0.5 kg

Force constant of the spring is 157 N/m

The object is released from rest when the spring is compressed 0.19 m.

(A) The force acting on the object is given by :

F = kx

F=157\times 0.19\\\\F=29.83\ N

(B) The force is simply given by :

F = ma

a is acceleration at that instant

a=\dfrac{F}{m}\\\\a=\dfrac{29.83}{0.5}\\\\a=59.66\ m/s^2

You are a member of an alpine rescue team and must get a box of supplies, with mass 3 kg , up an incline of constant slope angle
denis23 [38]

Answer:

v = 9.04 m / s

Explanation:

For this exercise we can use the relation that the work of the non-conservative force (friction) is equal to the variation of the mechanical energy of the system.

          W = Em_f - Em₀         (1)

Starting point. Lower slope

        Em₀ = K = ½ m v²

highest point. Where is the skier at a height h

        Em_f = U = m g h

The work of rubbing

        W = -fr x

the negative sign is because the friction force opposes the movement.

Let's set a reference system where the x axis is parallel to the slope and the y axis is perpendicular

let's use trigonometry to break down the weight

        cos θ = W_y / W

        sin θ = Wₓ / W

        W_y = W cos θ

        Wₓ = W sin θ

Y axis

        N - Wₓ = 0

        N = mg sin  θ

X axis

         fr = m a

the friction force has the expression

         fr = μ N

         fr = μ mg sin θ

we look for the job

         W = - μ mg sin θ  x

where x is the distance along the slope

       

we substitute in 1

         -μ mg sin θ x = mg h - ½ m v²

let's use trigonometry to find the distance x

        tan 30 = h / x

        x = h / tan 30

we substitute

          -   \mu \ mg \ sin \theta \  \frac{h}{tan 30} \ x = m gh - ½ m v²

we use  

          tan 30 = sin30 / cos30

         

          v² = 2g h + 2 μ g h cos 30

          v = \sqrt{ 2gh \ (1+ cos 30}

let's calculate

          v = \sqrt{ 2 \ 9.8 \ 4 \ (1 + 0.05 \ cos \ 30)}

          v = 9.04 m / s
