Тесты имеют различные нормы-шкалы значений: социальные, возрастные и т.П. Индивидуальный показатель теста соотносится с его нормой. Норма теста обычно определяется в результате тестирования большой выборки испытуемых определенного возраста и пола и усреднения полученных оценок с их последующей дифференциацией по возрасту, полу и ряду других показателей. Норма теста - это средний уровень развития большой совокупности людей, похожих на данного испытуемого по ряду социально-демографических характеристик. То есть, это средний диапазон значений на шкале измеряемого свойства.

Do all force interactions cause a noticeable change in motion? Explain your thinking?
!THANK YOU!
Answer:
No. If you apply a force in a chair, for example, you only will be able to move the chair if you beat the static frictional force. So, with that example, we can see that is not any type of force that can produce movement. The only force that produces movement is a result force which is non-zero.
How do vaccines provide immunity
Answer:
Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself.

How do the temperature curves in your graph show the range of temperature?

Step-by-step Explanation:
Question 4 (1 point)
How far does a sound wave travel in 3 seconds if the air temperature is 30 degrees
Celsius?
a) 114.33 m
b) 1047 m
c) 1029 m
d) 116.33 m
Answer:
B
Explanation:
v=349m/s
d=vt
d=349*3
d=1047m
WHY 349??
Because, velocity of sound increases about 0.6 m/s for every 1 degree celsius rise in temp.
Velocity of sound is about 343 m/s at 20 degrees C, so 0.6*10=6 more m/s, or 349 m/s. Kinda cool how temperature alters the speed of sound!

Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. They crash into each other and hold onto each other so that they move as one mass. How fast are they traveling? How would you find your answer?
Answer:
They traveling at along the direction of 55 kg kid.
Step-by-step explanation:
Conservation of momentum-
Momentum of a system is constant if there are no external forces acting on the system.
As they crash into each other and hold onto each other so that they move as one mass and no other force is acting on them, so conservation of momentum can be applied here.
The final direction of velocity will be opposite to the assumed direction of the mass of 40 kg.
This is a conservation of momentum problem. The equation relevant here is
[tex]\[m_1v_1+m_2v_2=\left ( m_1+m_2 \right )v_f\][/tex]
where m is the mass and v is the velocity. Because Amy and Jenny move as one mass after crashing (or colliding) with each other, this is an inelastic collision. What we to find is the final velocity, [tex]v_f[/tex], of both Amy and Jenny as a single body.
[tex]v_f=\frac{m_1v_1+m_2v_2}{\left ( m_1+m_2 \right )} = \frac{(55)(3)+(40)(5)}{(55+40)} = \text{3.84 m/s}.[/tex]
A wave with a frequency of 325 Hz. is travelling at a speed of 125 m/s. What is the wavelength of this wave?
Answer:
0.385 meters
Explanation:
Just remember this very simple equation:
velocity=(wavelength)*(frequency)
I always remember it as "Velma is Waving Frantically"
So, 125=(wavelength)*(325)
Therefore, wavelength=0.385 meters!

Which two statements describe what happens in both nuclear fusion and
nuclear fission reactions?
A. Each nucleus formed has fewer protons than the original nucleus
had.
B. Nuclei with small masses combine to form nuclei with larger
masses.
C. Radiation is released from the nuclei that undergo a reaction.
D. A small amount of the mass in each nucleus that undergoes a
reaction is converted to energy.
Answer:
C. Radiation is released from the nuclei that undergo a reaction.
D. A small amount of the mass in each nucleus that undergoes a
reaction is converted to energy.
Two statements, that describe what happens in both nuclear fusion and nuclear fission reactions, are:
Radiation is released from the nuclei that undergo a reaction.A small amount of the mass in each nucleus that undergoes a reaction is converted to energy.Hence, option (C) and (D) are correct.
What is nuclear reaction?A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.
Instead of being referred to as a nuclear reaction, the process is simply referred to as a sort of nuclear scattering if a nucleus interacts with another nucleus or particle and they subsequently separate without altering the nature of any nuclide.

Are acceleration and force proportional or inversely proportional values?
Answer:
Yes, acceleration and force are directly proportional to each other.
Explanation:
The force acting on an object is given by :
F = ma
Where
m is mass
a is acceleration
It can be clear from the above formula that the acceleration and the force are directly proportional to each other.

Answer:
5
Explanation:
From the attachement,
M.A = Load(L)/Effort(E)
M.A = L/E...................... Equation 1
Where M.A = .Mechanical Advantage, L = Load, E = Effort.
Given: L = 500 N, E = 100 N
Substitute these values into equation 1
M.A = 500/100
M.A = 5.
Hence the actual mechanical advantage of the pulley is 5

what is acceleration
Answer: acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
Explanation:
A sharpening wheel is traveling at 5 rad/s, it slows down to rest in 30 seconds while sharpening an axe. What is its angular acceleration?
Answer:
Angular acceleration [tex]= 0.167[/tex] rad/s^2
Explanation:
Given
Initial Angular velocity (w1) [tex]= 5[/tex] rad/s
Final Angular velocity (w2) [tex]= 0[/tex] rad/s
Time taken to change velocity from w1 to w2 [tex]= 30[/tex] seconds
Angular acceleration is equal to the change in angular velocity to the time taken for making thing change
Hence, Angular acceleration
[tex]\frac{w_2 -w_1}{t} \\\frac{5-0}{30}\\0.167[/tex]rad/s^2
The kinetic energy of a body moving at a speed of 10 m / s is equal to 1000 J. What is the body mass
Answer:
m = 20 kg
Explanation:
Given that,
The speed of a body, v = 10 m/s
Kinetic energy of the body, K = 1000 J
We need to find the mass of the body. The formula for the kinetic energy of a body is given by :
[tex]K=\dfrac{1}{2}mv^2\\\\m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 1000}{(10)^2}\\\\m=20\ kg[/tex]
So, the mass of the body is equal to 20 kg.

As a cold air mass advances on a warm air mass, what usually comes before it?
Answer: A cold front occurs when a cold air mass advances into a region occupied by a warm air mass. If the boundary between the cold and warm air masses doesn't move, it is called a stationary front.
Explanation: Two types of occluded front exist: the warm-type and the cold-type. They’re distinguished by the relative temperatures of the air mass ahead of the occlusion – in other words, the air mass ahead of the original warm front – and the air mass behind the cold front. If the air behind the cold front is colder than the air ahead of the occlusion, it shoves beneath that air (because it’s denser) to form a cold-type occluded front. If the air behind the cold front is warmer than the air ahead, it rides over it to form a warm-type occluded front – which appears to be the more common case. In either situation, the lighter warm air representing the air mass originally between the warm and cold fronts sits above the boundary between the two cooler air masses.
