Answer:

1. Option D) Deciding if the procedure, principles or techniques in question in a forensic case are generally accepted by the relevant scientific community.

2. Option A) thin-layer chromatography

3. Option A) when the jury considers the verdict

Explanation:

1. The Frye Standard is a procedure to determine if the piece of evidence is admissible in a court of law. This is a rigorous test to test how well the evidence can be used against a criminal or prove a case in the court of law. This came after a ruling that an experts advice only was insufficient to prove a case.

2. Thin layer chromatography is used to separate the ink components. This is because the ink is made of different components that have different volatlitities and solublies in the alcohol solution. The inks can be compared by looking at the partitioning coefficient and comparing the two distances traveled by the components.

3. The guilty cannot plead a case when the verdict has been given. At that moment, the case is closed.

Hello!

A graph that shows how position is depending on time is known as a Position Time Graph.

This is a graph used in Physics to help us understand how motion (positive/negative velocity) changes over a period of time. Motion can be seen in two ways on this graph: constant velocity and changing velocity, otherwise known as acceleration.

Hopes this help you answer your question!

The length of a simple pendulum is 0.66 m, the pendulum bob has a mass of 310 grams, and it is released at an angle of 12 degree

lina2011 [118]

A) the periodic time is given by the equation;
T= 2π√(L/g)
For the frequency will be obtained by 1/T (Hz)
T = 2 × 3.14 √ (0.66/9.81)
= 6.28 × √0.0673
= 1.6289 Seconds
Frequency = 1/T = f = 1/1.6289
thus; frequency = 0.614 Hz

b) The vertical distance, the height is given by
h= 0.66 cos 12
h = 0.65 m
Vertical fall at the lowest point = 0.66 - 0.65 = 0.01 m
Applying conservation of energy
energy lost (MgΔh) = KE gained (1/2mv²)
mgh = 1/2mv²
v² = 2gΔh = 2×9.81 × 0.01
= 0.1962
v = 0.443 m/s

c) total energy = KE + GPE = KE when GPE is equal to zero (at the lowest point possible)
Thus total energy is equal to;
E = 1/2mv²
= 1/2 × 0.310 × 0.443²
= 0.0304 J

A car starts from rest and travels for 5.8 s with a uniform acceleration of 1.6 m/s² in the negative direction. What is the fina

elena-s [515]

Answer:

Final velocity of the car will be -9.28 m/sec

Explanation:

We have given that the car starts from the rest so initial velocity of the car u = 0 m /sec

Acceleration of the car $a=1.6m/sec^2$ in negative direction so acceleration will be $a=-1.6m/sec^2$

From first equation of motion we know that

v = u+at

So $v=0+(-1.6)\times 5.8=-9.28m/sec$

So final velocity will be -9.28 m/sec

Ms. Stafford wants to try racing with a push start. A student pushes her at 5 m/s before the rocket kicks in. The rocket still o

Gnom [1K]

The initial velocity of Ms. Stafford is $v_0 = 5 m/s$ , while her acceleration is
$a=4 m/s^2$
This is a uniform accelerated motion, so we can calculate the total distance travelled by Ms. Stafford in a time of $t=7.0 s$ using the law of motion for a uniform accelerated motion:
$S=v_0t + \frac{1}{2} at^2 = (5 m/s)(7.0 s)+ \frac{1}{2}(2 m/s^2)(7.0 s)^2 = 84 m$
