Answer:
A
Explanation:
Forensic anthropology is a branch of anthropology that analyzes the remains of a body in order to solve criminal cases. A forensic anthropologist, therefore, is a scientist that studies and analyzes remains of bodies in order to unravel criminal cases.
Archaeology, on the other hand, has to do with the analyses of artifacts in relation to human culture. An archaeologist is a person that studies artifacts mainly.
Hence, while a forensic anthropologist specializes in the study of bodies, archaeologist searches and studies artifacts.

when your bikes in motion and you slam on the brakes, do you experience positive or negative acceleration?
Answer:
negative
Explanation:
A bird flies 1.3\,\text m1.3m1, point, 3, start text, m, end text with an average speed of 2.4\,\dfrac{\text m}{\text s}2.4 s m 2, point, 4, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction.
Explanation:
We are not asked what to look for, bot we can as well get the time taken by the bird to cover the distance at that speed.
Given
average speed = 2.4m/s
Distance = 1.3m
From the formula
Speed = Distance/Time
Time = Distance/Speed
Time = 1.3/2.4
Time = 0.542secs
Hence the total time covered by the bird is 0.542secs

Works by separating the different wavelengths of light, used to
determine which elements are present in a star or sample
Answer:the light from an astronomical source can consist of a continuous spectrum, an emission (bright line) spectrum, or an absorption (dark line) spectrum. Because each element leaves its spectral signature in the pattern of lines we observe, spectral analyses reveal the composition of the Sun and stars.

Answer:
I’m not sure bro
Explanation:
Answer:
The whole country is in a very seismic area,and they have the densest seismic network in the world, so they are able to record many earthquakes. The spares seismic instrumentation in those areas doesn't allow us to actually record all the smaller earthquakes.

Officer Piddington has been called to a murder scene. He arrives to find EMTs tending to the victim lying on the living room floor with a large knife protruding from his sternum. It is clear that this is where the crime occurred, and Officer Piddington does not see any evidence of dangerous chemicals on site. He secures the area and then begins to document the scene. What is one of the first things that Officer Piddington records in his notes about the crime scene?
The victim's past criminal history
A description of the crime scene when he arrived
The estimated time of death of the victim
A list of possible suspects involved in the crime
Answer:
The answer is B
Explanation:
The detective begins his/her documentation of the crime scene by writing down the date, time, and location of the crime scene. this is always important to start the report with so that any who reads the notes know when and wher this all happened before reading about evidence other wise the reader could be confused and pass evidence off as faulty.
Answer:
A description of the crime scene when he arrived

1. What is the sum of a vector 8 m south and a vector 12 m north? *
2. What is the sum of a vector 12 m north and a vector 8 m north? *
PLEASE SHOW WORK AND EXPLAIN
Explanation:
As they are in same direction, you can add them directly. And result is 12 + 8 m = 20 m North. If you use vector addition: Vectors = 12m & 8 m & angle b/w them is 0°(as both are in same direction).
A student athlete is participating in the hammer throw. The student rotates in uniform circular motion with the mass rotating 2.3 m away from the center of rotation.
Refer to the information and diagram shown above. The student athlete can rotate so that the object is moving with a speed of 10 m/s.
What is the acceleration necessary to keep the object in uniform circular motion?
The acceleration necessary to keep the object in uniform circular motion is 43.48 m/s²
From the question given above, the following data were obtained:
Radius (r) = 2.3 mVelocity (v) = 10 m/sAcceleration (a) =?The acceleration required to keep the object in circula motion can be obtained as follow:
a = v² / r
a = 10² / 2.3
a = 100 / 2.3
a = 43.48 m/s²
Thus, the acceleration required to keep the object in circula motion is 43.48 m/s².

5. An airplane must reach a velocity of 71 m/s for takeoff. If the runway is 1.0 km long, what
must the constant acceleration be?
Answer:
final velocity 'v' = 71m/s distance 's' = 1000m intial velocity 'u' =0 therefore,using third equation of motion v^2- u^2=2*a*s 71*71=2*a*1000 a=71*71/(2*1000 a= 2.52m/s^2
Explanation:
Is it possible to analyze the motion of an object that has non-constant acceleration?
Answer:
B
It is possible, but with formulas not yet derived by physicists.
Explanation:
Yes, it is possible to analyze the motion of an object that has non-constant acceleration but not with the help of Newton's equation of motion, as these equations are only valid for constant acceleration.
What are the three equations of motion?There are three equations of motion given by Newton,
v = u + at
S = ut + 1/2×a×t²
v² - u² = 2×a×s
Note that these equations are only valid for a uniform acceleration.
It is feasible to study an object's motion with non-constant acceleration, but not using Newton's equations of motion because these equations are only applicable for constant acceleration.
For analyzing the variable acceleration we have to use the calculus tools such as differentiation and integration.
Hence, it is possible to analyze the motion of an object that has non-constant acceleration

A 60-kg person walks from the ground to the roof of a 74.8 m tall building. How much gravitational potential energy does she have at the top of the building?
Given :
Mass of person, m = 60 kg.
Height of roof of building, h = 74.8 m .
To Find :
How much gravitational potential energy does she have at the top of the building.
Solution :
We know, gravitational potential energy is given by :
[tex]P.E = mgh[/tex]
Here, g = acceleration due to gravity = 9.8 m/s².
P.E = 60×9.8×74.8 J
P.E = 43982.4 J
P.E = 44 kJ
Hence, this is the required solution.

Explanation:
Johnny kicked a football from a hill 20 meters tall. The ball leaves at a 45.0 degree angle with an initial velocity of 30.0 m/second. How many seconds was the ball in the air? Report your answer to 3 sig figs. Seconds
Answer:
The value is [tex]t = 5.124 \ s[/tex]
Explanation:
From the question we are told that
The height of the tree is [tex]s = 20 \ m[/tex]
The angle the ball leaves is [tex]\theta = 45^o[/tex]
The initial velocity is [tex]u = 30.0 \ m/s[/tex]
Generally the vertical of the ball's initial velocity is mathematically evaluated as
[tex]u_y = u * sin (45)[/tex]
=> [tex]u_y =- 30 * sin (45)[/tex]
=> [tex]u_y = -21.21 \ m/s[/tex]
Here [tex]u_y[/tex] is negative because it is in the direction of the negative y-axis
Generally from kinematic equation we have
[tex]s = u_yt + \frac{1}{2} g t^2[/tex]
=> [tex]20= -21.21 t +4.9 t^2[/tex]
=> [tex]4.9 t^2 -21.21 t- 20= 0[/tex]
Solving using quadratic formula we have that
[tex]t = 5.124 \ s[/tex]
Need help ASAP!! Why does the ray bend as it enters the glass
Answer:
Explanation:
because as the light shines through the glass, The glass reflects the light from different places in the glass causing the light to bend
Answer: If light enters any substance with a higher refractive index it slows down. The light bends towards the normal line. If light travels enters into a substance with a lower refractive index it speeds up. The light bends away from the normal line.

In one of the printed docunent the unit of universal gravitational constant is given Nm2kg-2.Check its correctness for dimension analysis.
Answer:
It is correct
Explanation:
N is a unit of force
m for distance
and kg for mass
dimension of force is MLT-2
dimension of distance is L
dimension of mass is M
then. Nm2kg-2 must be equal to [MLT-2][L2][M-2]
or, Nm2kg-2 = [M-1 L3 T-2]. --------1
force (F) = G (m1 x m2)/d2
or G = Fd2/(m1m2)
G = (MLT-2 . L2)/M-2
= M-1L3T-2. -----------2
EQN 1 = EQN 2
so given unit is correct

A wagon, initially traveling at a constant 8.5 m/s, starts going down a hill that creates an
acceleration of 4.1 m/s2. How far downhill has the wagon gone after 2.7 s ?
Answer:
Explanation:
Given parameters:
Initial velocity = 8.5m/s
Acceleration = 4.1m/s²
Time = 2.7s
Unknown:
Distance downhill traveled = ?
Solution:
To solve this problem, we have to adopt the right motion equation;
S = ut + [tex]\frac{1}{2}[/tex]at²
where s = distance
u = initial velocity
a = acceleration
t = time taken
Insert the parameters and solve;
S = (8.5 x 2.7) + ([tex]\frac{1}{2}[/tex] x 4.1 x 2.7²)
S = 22.95 + 14.95
S = 37.9m
