A 2. 3-kg object traveling at 6. 1 m/s collides head-on with a 3. 5-kg object traveling in the opposite direction at 4. 8 m/s. If the collision is perfectly elastic, what is the final speed of the ?
Answers
The final speed of the system after the collision is 5.31 m/s.
To solve the problem, we can use the conservation of momentum and the conservation of kinetic energy.
First, we need to find the initial momentum of the system. We can use the convention that motion to the right is positive and motion to the left is negative. Therefore:
initial momentum = m1v1 + m2v2
= (2.3 kg)(6.1 m/s) + (-3.5 kg)(-4.8 m/s)
= 14.03 kg·m/s + 16.8 kg·m/s
= 30.83 kg·m/s (to the right)
The negative sign for the velocity of the second object is because it is traveling in the opposite direction.
Next, we can use the conservation of momentum to find the final velocity of the system. Since the collision is perfectly elastic, we can assume that kinetic energy is also conserved.
final momentum = initial momentum
= 30.83 kg·m/s
final momentum = (m1 + m2)vf
= (2.3 kg + 3.5 kg) vf
= 5.8 kg vf
Therefore, 30.83 kg·m/s = 5.8 kg vf, and:
vf = 30.83 kg·m/s / 5.8 kg
= 5.31 m/s
So the final speed of the system after the collision is 5.31 m/s.

Give a brief description of the factors involved in understanding the etiology of a disease.
Answers
\(\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}\)
Actually Welcome to the Concept of the Diseases.
When a doctor tries to figure out the cause of a disease, they are actually trying to figure out the etiology of the disease.
Etiology is the cause of a disease or the science that deals with such causes.
The word etiology comes from the Greek etio-, which means 'causation' and -ology, which refers to the scientific study of something (here relates to study or research on disease).
A disease's etiology, or cause, generally falls into three main categories; intrinsic, extrinsic and idiopathic.
1.) Intrinsic means coming from within. Therefore, any pathological, or disease-causing, change that has occurred from inside the body has occurred as a result of intrinsic factors.
e. g. Inherited conditions, or conditions that are passed down to you from your parents. An example of this is hemophilia, a disorder that leads to excessive bleeding.
2.)The second category of disease etiology is extrinsic etiologies. This means the cause of the disease, or pathological change, came from outside of the body.
e. g. Infectious agents like bacteria, viruses, fungi, and parasites.
3.)The third and final category of disease etiology is idiopathic, or of unknown cause.
e. g. It may be sudden pain in stomach,etc.
Ethology is the study of causation or origin. They have derived from the Greek meaning of reason and is the study of causes and is commonly used in medicine.

What is the universal law of gravitation, or NLG?
Every particle of matter in the universe is drawn to every other particle by a force that varies directly with their combined masses and inversely with their distance from one another.
Whether an object is moving or at rest, gravity still exerts its force on it.
In the given case, the general equation is as follows:
s = s₀+v₀t+1/2g\(t^{2}\)
where
s is referred to as position at time t,
s₀ is referred to as the initial position,
v₀ is referred to as the initial velocity,
g is referred to as the acceleration of gravity and
t is referred to as the elapsed time.
When the object leaves your hand, we would typically say that time is (t)=0.
An object initial velocity is increased when it is thrown, whereas it would be zero if it were simply dropped.
However, once it is out of your hand, gravity accelerates at the same rate in both directions. As a result, the downward acceleration is 9.8 meters per second squared.

Suppose a piece of food is on the edge of a rotating microwave oven plate. Does it experience nonzero tangential acceleration, centripetal acceleration, or both when: (a) The plate starts to spin
Answers
Answer:
the only acceleration it has is radial (centripetal)
Explanation:
The microwaves plate rotates at a constant speed after a very short period of acceleration.
Therefore we can apply Newton's second law
F = m a
where the acceleration is centripetal
a = v2 / r = w2 r
therefore as it rotates constant speed it cannot have a tangential acceleration since it changes the modulus of the speed.
Consequently the only acceleration it has is radial (centripetal)

From the question given above, the following data were obtained:
Accepted value = 238857 miles
Measured value = 226316 miles
Percentage error =.?
Next, we shall determine the absolute error. This can be obtained as follow:
Accepted value = 238857 miles
Measured value = 226316 miles
Absolute Error =?
Absolute Error = |Measured – Accepted|
Absolute Error = |226316 – 238857|
Absolute Error = 12541
Finally, we shall determine the percentage error. This can be obtained as follow:
Accepted value = 238857 miles
Absolute Error = 12541
Percentage error =.?
Percentage error = absolute error / accepted value × 100
Percentage error
= 12541 / 238857 × 100
= 1254100 / 238857
= 5.25%
Therefore, the percentage error is 5.25%.
How far would a space ship move between t 4s and t 8s if it was traveling with a uniform velocity from 75m/s at t=0 to 269m/s at t=12s
Answers
The spaceship would move a distance of 688 meters between t = 4s and t = 8s.
To calculate the distance traveled by the spaceship between t = 4s and t = 8s, we need to consider the average velocity over that time interval. Average velocity is defined as the total displacement divided by the total time.
Given that the spaceship is traveling with a uniform velocity, we can assume that the velocity remains constant throughout the entire interval.
The initial velocity at t = 0s is 75m/s, and the final velocity at t = 12s is 269m/s. The time interval we're interested in is 4s to 8s.
To calculate the average velocity, we sum the initial and final velocities and divide by 2:
Average velocity = (Initial velocity + Final velocity) / 2
Average velocity = (75m/s + 269m/s) / 2
Average velocity = 172m/s
Now, to find the distance traveled, we multiply the average velocity by the time interval:
Distance = Average velocity * Time interval
Distance = 172m/s * (8s - 4s)
Distance = 172m/s * 4s
Distance = 688m
Therefore, the spaceship would move a distance of 688 meters between t = 4s and t = 8s.

Carbon-14 is used to determine the time an organism was living. The amount of carbon-14 an organism has is constant with the atmosphere, but when an organism dies the carbon-14 decays at a half-life of 5,730 years. If an archeologist measured the amount of carbon-14 in an organism and it was 25% of the total amount of atmospheric C-14, what is the age of the organism? 1432.5 years 5,730 years 11,460 years 17,190 years
Answers
Answer:
The age of the organism is approximately 11460 years.
Explanation:
The amount of carbon-14 decays exponentially in time and is defined by the following equation:
\(\frac{n(t)}{n_{o}} = e^{-\frac{t}{\tau} }\) (1)
Where:
\(n_{o}\) - Initial amount of carbon-14.
\(n(t)\) - Current amount of carbon-14.
\(t\) - Time, measured in years.
\(\tau\) - Time constant, measured in years.
Then, we clear the time within the formula:
\(t = -\tau \cdot \ln \frac{n(t)}{n_{o}}\) (2)
In addition, time constant can be calculated by means of half-life of carbon-14 (\(t_{1/2}\)), measured in years:
\(\tau = \frac{t_{1/2}}{\ln 2}\)
If we know that \(\frac{n(t)}{n_{o}} = 0.25\) and \(t_{1/2} = 5730\,yr\), then the age of the organism is:
\(\tau = \frac{5730\,yr}{\ln 2}\)
\(\tau \approx 8266.643\,yr\)
\(t = -(8266.643\,yr)\cdot \ln 0.25\)

The best measurements of the mass of the black hole at the galactic center come from:.
Answers
The best measurements of the mass of the black hole at the center of the Milky Way galaxy come from observations of the orbits of stars and gas clouds near the galactic center.
In particular, astronomers have been able to observe the motion of stars and gas clouds that are very close to the center of the galaxy, within a few light-days of the suspected black hole.
By measuring the speed and direction of these objects, and analyzing their orbital trajectories, scientists can calculate the gravitational force required to keep them in orbit. The size of this force depends on the mass of the central object, which is likely to be a black hole.
Through this method, astronomers have estimated that the black hole at the center of the Milky Way, known as Sagittarius A*, has a mass of about 4 million times that of the sun.
This estimate has been refined and confirmed over several years of observations, and is currently the most accurate measurement of the mass of a supermassive black hole.
