Answer:
There are four natural states of matter: Solids, liquids, gases and plasma.
Explanation:
The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don't move much.

5. While you're ice-skating with your friends, you push off from one end of
the rink and slide forward. Based on Newton's first law of motion, what
is true?
A. You will lose your balance and fall over before you reach the middle of
the ice rink
B. You will continue to slide across the ice until a force makes you stop or
change direction
C. The force of gravity will make you keep your velocity until your friends
make you stop
D. The size of your ice skates will determine how quickly or slowly you
travel across the ice
ype here to search
Answer:
B
Explanation:
Newton's 1st law of motion is anything that is at rest remains at rest and anything in motion remains in motion so you will continue to slide until you come into contact with the opposite wall or another force.

Why water is not used as a thermometric liquid?
Answer:
Explanation:There are many reasons why water is not used as a thermometric liquid (or is less preferred), chief among which is its transparency. It is thus comparatively harder to make any readings with it. It also has a lower boiling and higher freezing point compared to most liquids.

A team of seven psychologist is study love, but each psychologist is working from a different perspective. In your opinion, what might each pyschologist stufy?
Answer:
- Behavioral Psychologists
- Psychodynamic Psychologist
- Biological Psychologist
- Cognitive Psychologist
- Evolutionary Psychologist
- Socio - Cultural Psychologist
- Humanist Psychologist
Explained in explanation section
Explanation:
There are different classes of psychologists but for the purpose of this question we need just 7 that would fit into the study of love. These 7 will be;
1) A behavioral Psychologist might study behaviors associated with love, such as hugging, caressing or kissing.
2) A psychodynamic psychologist might study how a people's challenges with love are caused by unmindful and unresolved conflicts.
3) A biological psychologist might study which chemicals in the brain such as dopamine make people feel loved. He might also study parts of the what parts of the brain are active when people are in love.
4) A cognitive psychologist might study how people's cognitive processes will change when they are in love.
5) An evolutionary psychologist might study how certain actions or behaviors associated with love provided our forefathers with sufficient knowledge to handle their love problems.
6) A sociocultural psychologist might study how people express love in in various cultures across the world.
7) A humanistic psychologist might study the behavior of those who feel most loved and the impact it has in their lives
Answer:
A psychodynamic psychologist might study how a person's problems with love are caused by unconscious, unresolved conflicts. A behaviorist might study observable behaviors associated with love, such as hugging or kissing. A cognitive psychologist might study how a person's cognitive processes change when one is in love.
A ball rolls at a speed of 6cm/s how far does the ball roll in 40 seconds ? ____cm
The distance time graph of a body is a straight line parallel to the time axis. What
information does the graph convey regarding the motion of the object?
Explanation:
The object is not moving, because the distance is a constant value regardless of the time value.
A person runs 15.0 km north then turns around and runs 10.0km south.
a) what is his distance?
b) what is the person's displacement?
Answer:
A. 25kmB. 15kmExplanation:
In this problem, we are expected to solve for the total distance covered by the person, and the person's displacement.
a) what is his distance?
this can be gotten by summing up all the individual distances covered by the person
total distance= 15+10
total diastance= 25 km
b) what is the person's displacement?
the displacement is the distance measured away from a point
this can be gotten by subtraction the final distance/point from the initial distance/point
displacement= 25-10
displacement= 15km

A car accelerates from rest to 90m/s in 3 seconds. What is the acceleration and how far did it travel?
Answer:
Explanation:
1.)acceleration= final velocity-initial velocity/time
90m/s-0m/s /3seconds
=30m/s^2
2.) distance= speed*time
90m/s*3seconds
=270m

1) Describe the motions of the moon relative to the Earth and the sun. Explain how this causes us to see phases of the moon, and identify these phases by name.
Answer:
Explanation:
The moon is a natural satellite of the earth, which performs rotational and revolutionary motions simultaneously. As the earth rotates about its axis, the moon rotates round it. But revolves round the Sun, as the earth also revolves round the Sun.
The motion of the moon causes series of its phases. Some major phases of the moon are, new moon, 1st quarter, full moon, and 3rd quarter (last quarter).
Since the moon reflects the light from the Sun, the face of the moon reflecting the light from the Sun changes gradually with respect to its motion.
At new moon, the face of the moon reflect no light. But reflects 100% at full moon. While both 1st and 3rd quarters show partial reflections.
If several negative charges surround a large positive charge, the total force on a far away charge is reduced. What is this effect called
Answer:
this effect is called SCREENING
Explanation:
When a positive charge is surrounded by several negative charges at a long distance, an apparent decrease in the positive charge is observed, this effect is called SCREENING and is noticeable in multielectronic atoms
This effect is responsible for the decrease in ionization energy in the larger atoms.

Which statement describes an energy measurement?
There are no statements provided for my me to choose from, but i'll try.
Here's what I've got for ya:
1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter. 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts. 1 kilowatt-hour is the energy of one kilowatt power flowing for one hour.
Prob. not that helpful, sorry, but I can't read your mind to understand what the statements were, sorry.
Hope this is at least kinda helpful!

Which is always true in a closed system?
Acceleration is not constant.
Mass is not conserved.
Momentum is conserved.
Velocity is constant.
Answer:
The correct option is momentum is conserved
Explanation:
A closed system is a system that is independent/free of external factors/force and does not exchange matter with its surrounding. Since a close system is free of external factors/force; acceleration is constant in it, mass is conserved in it and there will be changes in velocities of objects in the closed system.
This question actually seeks to test our knowledge of the law of momentum. The law of conservation of momentum states that the momentum of a closed system is conserved.
C: Momentum is consevered
water in a cup and a kettle can have the same temperature even though the quantities are different . give reasons
Answer:
The reason is because both are exposed to a virtually infinite heat sink, due to the virtually infinite mass and of the surrounding environment, compared to the sizes of either the cup or the kettle such that the equilibrium temperature, [tex]T_{(equilibrium)}[/tex] reached is the same for both the cup and the kettle as given by the relation;
[tex]\infty M_{(environ)} \times c_{(environ)} \times (T_2 - T_1) = m_{1} \times c_{(water)} \times (T_3 - T_2) + m_{2} \times c_{(water)} \times (T_4 - T_2)[/tex]
Due to the large heat sink, T₂ - T₁ ≈ 0 such that the temperature of the kettle and that of the cup will both cool to the temperature of the environment
Explanation:
What is the momentum of a 3 Kg ball that is traveling at 9 m/s to the left?
Answer:
Explanation:
momentum =mv
p=mv
given mass=m= 3 kg
given velocity=v=9 m/s
therefore p is
p=mv
p=3*9
p=27 kgm/s
