You are one of the forensic anthropologist working on the Romanov Family investigation. You and your team are trying to determine the height of each of victim. Which bone will you analyze to create a profile of the victims?

Answers

Answer:

Femur

Explanation:

The bone to forensically analyze in order to create a height profile of the victims would the femur.

The approximate height of a human can best be estimated by measuring the length of the bone that runs from the hip to the knee, otherwise known as the femur.

For the males, the length of the femur in centimeters is multiplied by 2.32 followed by the addition of 65.53 in order to arrive at the approximate height of the individual. For the females, on the other hand, the length of the femur in centimeters is multiplied by 2.47 followed by the addition of 54.1.

Hardin electronic corporation is designing a new cell phone, they need a solid material that will insulate the phone and product their users from electric shock. Which material would best fit the needs of Hardin engineers A. A non-metal B. A metalloid C. A metal D. A semiconductor

Answers

Answer:

A

Explanation:

The material that would best suit Hardin electronic corporation's need would be a non-metal.

Non-metals are naturally occurring substances or materials that lack the properties of metals. In other words, non-metals are poor conductors of heat and electricity, unlike metals.

Solid non-metals are, therefore, used as insulators in the design of materials. Hence, the best material for Hardin electronic corporation to use that will insulate the phone and protect their users from electric shock would be a non-metal.

The correct option is A.

Answers

Answer:

1 m²

Explanation:

The area of the floor covered by his both feet can be found by using the formula

[tex]a = \frac{f}{p} \\ [/tex]

f is the force

p is the pressure

From the question we have

[tex]a = \frac{400}{400} = 1 \\ [/tex]

We have the final answer as

1 m²

A student moves a box across the floor by exerting 56.7 N of force and doing 195 J of
work on the box. How far does the student move the box?
A.3.4 m
B. 11,056 m
C.138 m
D.0.29 m

Answers

Answer:

A. 3.4 m

Explanation:

Given the following data;

Force = 56.7N

Workdone = 195J

To find the distance

Workdone is given by the formula;

[tex] Workdone = force * distance[/tex]

Making "distance" the subject of formula, we have;

[tex] Distance = \frac {workdone}{force} [/tex]

Substituting into the equation, we have;

[tex] Distance = \frac {195}{56.7} [/tex]

Distance = 3.4 meters.

2. An 873 kg dragster accelerates at a rate of 44.6 m/s during a race.
a. What is the magnitude of the net force exerted on the dragster during this time?
Known (Given):
=
Unknown:
Fnet =
Equation:
Fret=ma (or m*a)
Solution:

Answers

Answer:

38,673.9N

Explanation:

According to newton's second law:

Force = mass * acceleration

Given

Mass = 873kg

acceleration = 44.66m/s²

Magnitude of the force is expressed as;

F = ma

F = 873 * 44.6

F = 38,673.9N

Hence the magnitude of the net force exerted on the dragster during this time is 38,673.9N

Which element accumulates in the environment due to the use of
fertilizers?
A. oxygen
B. hydrogen
C. nitrogen
D. carbon

Answers

To Find :

Which element accumulates in the environment due to the use of  fertilizers.

Solution :

Most of the fertilizers used in daily practice are nitrogen fertilizers .

When soil became waterlogged, soil organisms take the oxygen they need from nitrates, leaving the nitrogen in a gaseous form which escapes into the air.

Also, nitrogen is very stable and did not participate in most of the reactions.

So, nitrogen is accumulates in the environment .

Therefore, option C. is correct.

As the distance between two charged particles increases, the force of attraction __________(increases/decreases). This is a(n) __________ (direct/indirect) relationship. Explain your evidence and reasoning with observations from the simulation.

Answers

Answer: decreases.

direct.

Explanation:

when you have two objects which are far apart from each other,  when the distance increases the forces of attraction decreases and vice versa when the distance decreases the forces of attraction also increases.

this is a direct relationship, from careful observation and monitoring of the simulation, a pattern is noticeable by which an increase in one variable causes an opposite effect on the other variable.

How does the electric force between two charged particles change if the
distance between them is reduced by a factor of 2?
A. It is reduced by a factor of 2.
B. It is increased by a factor of 4.
C. It is increased by a factor of 2.
D. It is reduced by a factor of 4.

A rock is dropped into a canyon that is 0.3 km deep. Determine the time it takes the rock to hit the bottom of the canyon?

Answers

Answer:

rock of mass m is dropped to the ground from a height h. A second rock, with mass 2m, is dropped from the same height. When the second rock strikes the ground, what is its kinetic energy? (a) Twice that of the first rock, (b) four times that of the first rock, (c) same as that of the first rock, (d) half as much as that of the first rock, (e) impossible to determine.

If a  rock is dropped into a canyon that is 0.3 km deep, then the time taken by the rock to hit the bottom of the canyon would be 7.82 seconds.

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

Keep in mind that these calculations only apply to uniform acceleration.

As given in the problem, if a rock is dropped into a canyon that is 0.3 km deep.

By using the second equation of motion given by Newton,

S = ut + 1/2at²

300 = 0 + 0.5 × 9.8 × t²

t² = 300 / 4.9

t = 7.82 seconds

Thus,  the time taken by the rock to hit the bottom of the canyon would be 7.82 seconds.
