How are reversibility, time, and entropy connected
Answer:
As one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease. ... Thus, entropy measurement is a way of distinguishing the past from the future.

One advantage that sexual reproduction has over asexual reproduction is the ability to produce genetic diversity. Why is genetic diversity an advantage?
Answer:
Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population

Think about the types of forces holding the atoms together in different chemicals. Are there any patterns that can be drawn from the data? Explain.
Hello. You did not enter the data to which this question refers, which makes it impossible for it to have an exact answer. However, I will try to help you in the best possible way.
The forces that hold the elements together are called intermolecular forces. They are formed by covalent bonds between the molecules and can be called: dipole-induced (occurs between nonpolar molecules that have a negative pole and a positive pole) and dipole-dipole (occurs between polar moileculas, except when hydrogen is present).
A book is resting on a table. The table is raised on one end to an angle of 15° to the floor. If the book remains at rest, what keeps the book from sliding?
A. rolling friction
B. static friction
C. sliding friction
D. fluid friction
Answer: Static Friction
Explanation: As you tilt the book you know that it will stay fixed to start with, but eventually, once the angle is large enough, the book will start to slide. It is the static friction force that holds the book in place at small angles of tilt.
The book remains at rest if A book is resting on a table. The table is raised on one end to an angle of 15° to the floor due to static friction, so option C is correct.
What is static friction?An item is kept at rest by the force of static friction. The phrase "static friction" can be defined as "the friction people perceive when they attempt to move a stationary object on a surface, but without actually causing any relative motion between the body and the surface it is on."
You can predict that the book will initially remain fixed when you tilt it, but once the angle is sufficiently large, it will finally begin to slide. The book is held in place at slight tilt angles by static friction force.
The formula for the coefficient of static friction is μ = tan θ, here θ is the angle of inclination if the angle is bigger the friction force is more but at 90° when the book is vertical then the friction force will not work on the book
Therefore, the book remains at rest if A book is resting on a table. The table is raised on one end to an angle of 15° to the floor due to static friction.

3. A 6 kg block moving to the right at 4 m/s collides with and sticks to a stationary block of unknown mass. If the two blocks move off to the right at 3 m/s, what was the mass of the stationary block?
Answer: 2kg
Explanation:
This problem is a textbook conservation of momentum problem. The intial momentum is equal to the final momentum. For the initial state of each block, only the first one was moving. Then they both combine to move together.
Pi = Pf
with p = mv
(6kg)*(4m/s) = (6kg+xkg)(3m/s)
Let x equal the unknown mass of block 2
24 = 18 + 3x
6 = 3x
x = 2kg

Explanation:
An eagle flying 10 meters per second swoops down to the ground to catch a snake speed velocity or acceleration
Answer:
Velocity because it has both magnitude (10m/s) and direction (to the ground).
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
[tex]Velocity = \frac{distance}{time}[/tex]
In this scenario, an eagle flying 10 meters per second swoops down to the ground to catch a snake. Therefore, this is an example of velocity.

Which one, mass or weight, would change if you were to travel to another planet or moon?
Answer:
The answer is weight.
Mass is constant, your mass, height and width won’t change. So that leaves weight.
Do you hear sounds around you as one frequency at a time or as many frequencies at once?
Answer:
The commonly stated range of human hearing is 20 Hz to 20 kHz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.

Two charges separated by one meter exert a 9 N force on each other. If the charges are pushed to a 3 meter separation, the force on each charge will be 3 N.
True or False?
Answer:
False
Explanation:
The formula of force that exists between two charges is expressed as;
F = kq1q2/r²
If two charges separated by one meter exert a 9 N force on each other, the;
9 = kq1q2/1²
9 = kq1q2 ..... 1
If the charges are pushed to a 3 meter separation, then;
F = kq1q2/3²
F = kq1q2/9 .... 2
Divide both equations;
9/F = (kq1q2)/ kq1q2/9
9/F = kq1q2 * 9/ kq1q2
9/F = 9
F = 9/9
F = 1N
Hence if the charges are pushed to a 3 meter separation, then the force on EACH charge will be 1N. Hence the answer is False
How do you solve the resultant force and direction.
Answer:
To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force. A force of 5 N acts to the right, and a force of 3 N act to the left. Calculate the resultant force.Which model shows how a comet's tail changes during its orbit?

particle has 17.5 joules of kinetic energy and 12.5 joules of gravitational potential energy at one point during its fall from a tree to the ground. An instant before striking the ground, how much mechanical energy — rounded to the nearest joule — does the particle have?
Answer:
Em = 30 J
Explanation:
The principle of conservation of mass and energy is one of the most important in physics, it establishes that energy cannot be created just by transforming it.
Therefore, the mechanical energy at a point is the same throughout the movement, only in some parts it will be kinetic, in others potential and in the intermediate points a mixture of the two, but the total value is always the same.
Em = K + U
Em = 17.5 + 12.5
Em = 30.0 J
At the point just before touching the ground the mechanical energy is the same Em = 30 J

A skateboarder rolls down the sidewalk with an initial velocity of 0 m/s. If her acceleration is
1.5 m/s”, how long will it take her to reach the bottom 120m away?
Answer:
80m/s
Explanation:
to find it you have to work it out by using the formula distance divided by speed to find time.
The time taken by the skateboarder to reach the bottom 120m away is 80 sec.
What is Acceleration?Acceleration may be defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities as it has both magnitude and direction.
When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing. If an object is speeding up and moving in a positive direction, it has a positive acceleration.
According to the question,
Speed of the skateboarder = 1.5 m/s
The total distance needs to be traveled = 120m
Total time taken =?
The Formula for calculating time is as follows:
Speed = Distance/time. Time = Distance/speed = 120/1.5 = 80 seconds.Therefore, the time taken by the skateboarder to reach the bottom 120m away is 80 sec.
