Answer:
the answer is B
Explanation:
The development of the theory of reinforcement by B. F. Skinner (Burrhus Frederick Skinner) and his behaviors support for its application to learning contributed to the emergence of the behaviorism and programmed instruction movements. Thus, option B is correct.
What psychologist believed that behaviors by favorable?Small instructional frames, self-pacing, active learner reaction to inserted questions, and fast feedback regarding behaviors the accuracy of a response are all characteristics of programmed instruction.
In essence, individualized education substitutes methodical or pre-programmed materials for the behaviors. Individualized teaching can be delivered by print, computer, or other medium as long as it is founded on the ideas mentioned above.
Therefore, The psychologist who believed that behaviors that are followed by favorable consequences tend to be repeated was B. F. Skinner.

where does energy go if work is done by a non-conservative force ?
Answer:
The energy changes
Explanation:
When an non-conservative force (for example friction, air resistance, applied force) does work on an object, the total mechanical energy (Ek+Ep) of that object changes. If positive work is done, then the object will gain energy. If negative work is done, then the object will lose energy.

A force of 25 newtons moves a box a distance of 4 meters in 5 seconds.
The work done on the box is [___] Nm, and the power is [___] Nm/s.
h e l p
Answer:
100 Nm and 25Nm/s.
Explanation:
Given the following data;
Force = 25N
Distance = 4m
Time = 5secs
To find the workdone;
Workdone = force * distance
Substituting into the equation, we have;
Workdone = 25*4
Workdone = 100 Nm
To find the power consumed;
Power = workdone/time
Substituting into the equation, we have;
Power = 100/4
Power = 25Nm/s
The work done on the box is 100 Nm, and the power is 25 Nm/s.

A 700-kg car, driving at 29 m/s, hits a brick wall and rebounds with a speed of 4.5 m/s. If the car was in contact with the wall for 0.30 s, what force did the wall exert on the car during the collision?
Answer:
57166.6NExplanation:
Step one:
given data
mass=700kg
initial velocity u=29m/s
final velocity=4.5m/s
time t= 0.3second.
Step two:
The expression for the momentum is given as
FΔt=mΔv
make F subject of the formula
F=mΔv/Δt
Substitute our given data we have
F=700(29-4.5)/0.3
F=700*24.5/0.3
F=17150/0.3
F=57166.6N
the force is 57166.6N

4. Is the force of the earth’s gravity on the sun stronger, weaker, or the same as the force of the sun’s gravity on the earth? Explain why the sun’s attraction affects the motion of the earth more than the earth’s attraction affects the sun’s motion. Employ Newton’s second and third laws in your answer.
If anyone could help me at all, with either question it would be greatly appreciated, Physics is my hardest subject, and I struggle with it.
Answer:
Explanation:
3. Newton’s third law explains how every action has an equal but opposite reaction, meaning that forces comes in pairs. While the locomotive’s wheels are pushing back against the ground as the action force, the ground is producing a reaction force towards the locomotive, propelling it forward. Another pair of forces that act on the locomotive is gravity and normal force. While gravity is pulling the locomotive towards the ground, the normal force the ground exerts on the locomotive is why the locomotive doesn’t fall through the ground.
4. The force of Earth’s gravity on the Sun is weaker than the force of the Sun’s gravity on Earth. The Sun’s attraction affects the motion of Earth more than the Earth’s attraction affects the Sun’s motion because according to Newton’s second law, force has mass as one of its factors. The Sun has a significantly higher mass than Earth, meaning that its force of gravity would also be significantly higher. Newton’s third law is why the Earth doesn’t get marginally closer to the Sun, stating that every action has an equal and opposite reaction. As the Sun is pulling Earth towards itself, Earth is pulling away from the Sun.

Ana exerts a force of 20 N on a volleyball that has a mass of 0.15 kg. What is the force that the volleyball exerts on Ana?
0.15 N
20 N
19.85 N
20.15 N
Answer:
20 N
Explanation:
The question above is related to "Newton's Third Law of Motion." It states that every action is being opposed by a reaction of equal size but different direction.
The action force in the situation above is 20 N while the reaction force here is the one coming from the volleyball. So if the action force is 20 N then it's a common sense that the reaction force is also 20 N.
Thus, 20 N is the amount of force that the volleyball is exerting on Ana.
Answer:
the answer is 20 N

a shot is fired with a velocity 100m/s in a direction making an angle 60 degree with vertical. calculate its time flight, maximum height reached and its horizontal range
Answer:
#Horizontal component of 100m/s=100 sin60=50×(root 3)=50×1.732=86.6m/s
#Vertical component of 100m/s=100 cos 60°=100/2=50m/s
(¡) Maximum height it can reach=(v^2+u^2) /2a=0+(50^2) / 2×(-10)=125m
(¡¡) The time takes to reach the maximum height =2S/(u-v)=125×2/(50-0)=5s
(¡¡¡) Horizontal range=ut=86.6×5=433m
Explanation:
# At the highest point (vertical) velocity is zero
#Velocity (horizontal) remains constant
(¡)By v^2=u^2+2as equation
(¡¡)By S=1/2(u+v)t equation
(¡¡¡) S=ut therefore horizontal range=ut

an electric motor converts electrical energy into what kind of energy?
A) potential
B) kinetic
C) stored
D) chemical
Answer:
B.) Kinetic energy.
Explanation:
A better answer would be mechanical energy, but they do not have that up there.
An electric motor converts electrical energy into kinetic energy. The rotational kinetic energy of the motor is its mechanical energy to work.
What is energy transformation ?Energy can neither be created nor be destroyed. However, it can be transformed from one form to the other. Hence, the total energy of a system is conserved.
The energy lost in one form is equal to the energy gained in another form. We are using many electrical devices all are working under the process of energy transformation.
In an electric motor, the electrical energy is converted to the rotational kinetic energy of the motor. It is used for mechanical work of the motor. The rotational kinetic energy make the motor rotating. Hence, option B is correct.

In this chemical reaction, one or more atoms replaces a part of a
compound.
*
synthesis
decomposition
combustion
replacement
neutralization
Explanation:
If there are more reactants than products, it is a synthesis reaction. If oxygen is a part of the reactant, it is a combustion reaction. If one ion replaces another, it is a single replacement reaction. If there are two compounds in a reactant where cations switch, it is a double replacement reaction.
