Answer:
mowing a lawn
Explanation:
Entropy is the degree of disorderliness of a system. As a body moves from a more ordered state to a less ordered one, the entropy of the system increases.
Mowing a lawn is a typical example of increasing entropy. When a lawn is being mowed, the grasses becomes disordered without any fixed orientation. Folding a clothe is trying to bring orderliness to the clothe patterning. Washing dishes will make one arrange them in an ordered way. Falling leaves brings leaves together.Answer:

Answer:
d
Explanation:
Answer:
D. A snowball grows as more snow sticks to it.
Explanation:
When a star is born, it’s fairly small. However, the stars gravitational pull brings more things (for lack of better term) into it therefore increases it’s size as a snowball would as more things (again, no better term) stick to it.

Five locations are marked on the world map. Which location is most prone to hurricanes?
Answer: A
Explanation:
Location A represents the Caribbean region which is known for tourist attractions such as nice beaches. It is also known however, for devastating hurricanes.
Apart from mostly being islands, which puts them at risk of being in Hurricane paths, the Caribbean is warm and the air is moist. Hurricanes derive energy from these two things which is why Hurricanes attack the Caribbean rather frequently.
Answer:
Based off the picture the guy above showed me, the correct answer would be A

A student lifts a 2 kg book from the floor to a desk that is 0.5 meters high. How much work does the student do?
Answer:
W = 9.8 J
Explanation:
Given that,
Mass of the book, m = 2kg
A student lifts it from the floor to a desk that is 0.5 meters high.
We need to find work done by the student. The work done in lifting the book is given by :
W = mgh
Put all the values,
W = 2 kg × 9.8 m/s² × 0.5 m
W = 9.8 J
So, the required work done is 9.8 J.

Explain in detail how educational institutions and personal ideology affect the influence of contemporary psychological
perspectives.
Answer:
Educational institutions can influence what psychological perspectives are taught, studied, and researched. Take, for example, behaviorism. Before the cognitive perspective re-emerged, behaviorism was the dominant perspective being taught in most universities. Personal ideology can also affect which perspective a psychologist supports, the course of research a psychologist undertakes, and also a psychologist's perception and interpretation of research findings. For example, during the dominance of behaviorism, psychologists were discouraged from studying cognitive processes. As a result, much of the research conducted had a behaviorist slant to it.
Explanation:
Write the equations of motions
Answer:
In physics, equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time.[1] More specifically, the equations of motion describe the behaviour of a physical system as a set of mathematical functions in terms of dynamic variables. These variables are usually spatial coordinates and time, but may include momentum components. The most general choice are generalized coordinates which can be any convenient variables characteristic of the physical system.[2] The functions are defined in a Euclidean space in classical mechanics, but are replaced by curved spaces in relativity. If the dynamics of a system is known, the equations are the solutions for the differential equations describing the motion of the dynamics.

What is the difference between catastrophism and uniformitarianism
Explanation:
Catastrophism is a geological concept or ideology that was formerly in place. It suggests that the earth crust has evolved through only drastic and violent geological events.
Uniformitarianism suggests that the earth carefully evolved over a period of time and that the processes that are occurring today have occurred in times past.
Catastrophism presents a drastic and rapid evolution of the crust. Uniformitarianism takes a gradual approach to events and suggests that we can use the present to unravel the past.A train car of mass 16,500 kg moves along the railroad track with a constant speed of 14 m/s.

Rose got out of bed and walked from her room to the bathroom 10 m/s in 2s. She was traveling southeast. What was her acceleration?
Answer:
Acceleration = 5m/s² Southeast
Explanation:
Given the following data;
Final velocity = 10 m/s
Time = 2secs
To find acceleration;
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
We know that Initial velocity = 0m/s
Substituting into the equation, we have;
[tex]a = \frac{10 - 0}{2}[/tex]
[tex]a = \frac{10}{2}[/tex]
Acceleration = 5m/s² Southeast.
A truck travels to and from a stone quarry that is located 2.5 km to the east. What is the total distance traveled by the truck? .00025____________________ What is its displacement? .00025
Answer:
5 km
0
Explanation:
The question says the truck travelled to and fro from the stone quarry.
When going to the stone quarry, the distance was 2.5 km to the east.
On returning, the distance back is also 2.5km
Therefore total distance travelled is 2.5km + 2.5km
= 5km
The displacement 8s dependent on what is the initial and also the final position. The initial and the final position are one and the same thing. Because the truck starts and goes back to the same position, the displacement is zero.

Rahul runs a distance of 12
km with an average speed of 4.5 km/h and
Rita runs 1.6 km within 15 minutes. Who
runs faster?
Answer:
Rita runs faster
Explanation:
To obtain the answer to the question given, we determine the speed of Rita. This can be obtained as follow:
Distance = 1.6 km
Time = 15 mins
Speed =?
Next, we shall convert 15 mins to hour. This can be obtained as follow:
60 mins = 1 h
Therefore,
15 mins = 15 mins × 1 h / 60 mins
15 mins = 0.25 h
Thus, 15 mins is equivalent to 0.25 h.
Finally, we shall determine speed of Rita as follow:
Distance = 1.6 km
Time = 0.25 h
Speed =?
Speed = distance / time
Speed = 1.6 / 0.25
Speed = 6.4 Km/h
Thus Rita's speed is 6.4 Km/h
Comparing the speed of Rahul and Rita
Rahul's speed = 4.5 km/h
Rita's speed = 6.4 Km/h
We can see that Rita's speed is greater than Rahul's speed. This simply indicates that Rita runs faster than Rahul.

A student pushes a 12 kg block on a frictionless horizontal surface if the block is initially at rest what is the speed of the block after the student pushes the block for five seconds with an acceleration of 2 m/s squared
Answer:
20N
Explanation:
Given parameters:
Mass of the block = 4kg
Acceleration = 5m/s²
The speed of the block after the student pushes it is 10m/s.
Given the data in the question;
Mass of block; [tex]m = 12kg[/tex]Since the block is initially at rest,
Initial velocity; [tex]u = 0[/tex]Time taken; [tex]t = 5s[/tex]Acceleration; [tex]a = 2m/s^2[/tex]Final velocity; [tex]v =\ ?[/tex]
To determine the final velocity; we use the First Equation of Motion:[tex]v = u + at[/tex]
Where v is final velocity, u is initial velocity, a is acceleration and t is time taken.
We substitute our values into the equation
[tex]v = 0 + [ 2m/s^2\ *\ 5s]\\\\v = 2m/s^2\ *\ 5s\\\\v = 10\frac{ms}{s^2}\\\\v = 10m/s[/tex]
Therefore, the speed of the block after the student pushes it is 10m/s.

You are freezing juice to make your own popsicles. Describe what happens on a molecular level as the juice freezes. Be sure to us e appropriate science vocabulary in your response.
Answer:
When water freezes to form ice, the molecules would be vibrating in place rather than moving round. It is a result of a decrease in the kinetic energy of the molecules of water. It is said that the temperature and the kinetic energy of the molecules is directly proportional which means that when temperature is increased, the kinetic energy of the molecules would increase as well making the molecules move around. However for this case, when we day the system is cooled then it means the temperature is decreased which would result to the decrease of the kinetic energy of the molecules.

The unit for acceleration is always
Explanation:
Because acceleration is velocity in m/s divided by time in s, the SI units for acceleration are m/s2, meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second. ... The quicker you turn, the greater the acceleration.
why does a Ray of light passing through a glass slab not shown dispersion?
Answer:
After refraction at two parallel faces of a glass slab, a ray of light emerges in a direction parallel to the direction of incidence of white light on the slab. As rays of all colours emerge in the same direction (of incidence of white light), hence there is no dispersion, but only lateral displacement.
A man swings a bucket on a 120-cm rope with a tangential speed of 4.5 m/s. If the magnitude of the centripetal force is 25 N, what is the bucket’s mass?
Answer:
the buckets mass is 346g if im not mistaken
Explanation:
Mass of the bucket is 1.48kg
Centripetal force f=25N
Radius r=1.2m
speed v=4.5m/s
By the formula of centripetal force,
Centripetal force = mass x velocity2 / radius on putting the values
25= {m*4.5*4.5}{1.2}
m={250*12}{45*45}
={40}{27}
