Answer:
28 J
Explanation:
Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.
In physics, mechanical energy (Emech) is the energy associated with the motion and position of an object usually in some force field.
Therefore:
ME = KE + PE = 25 + 3 = 28 J
Answer:
Power = 24.41Watts
Explanation:
Find the diagram attached
Power output = Force * distance/Time
Given
Force = 120lb
Distance = 9inches
Time = 5sec
Since
1lb = 4.4482216153 N
120lb = 120 * 4.4482216153
120lb = 533.787N
9in to meters
9in = 0.0254*9
9in = 0.2286N
Power = 533.787*0.2286/5
Power = 24.41Watts
Answer:
Explanation:
From Newton's 2nd Law, we have 
. Using this, we can find the acceleration of the object:
.
Now that we've found the block's acceleration, we can use the following kinematics equation to find its final velocity after 2 seconds:
*Assumption: The block is initially at rest and has a initial velocity of zero. Otherwise, the question is unsolvable.
The theory drives this teacher's practices is Behaviorist.
<h3>
Who is a Behaviorist?</h3>
- A methodical approach to analyzing human and animal behavior is called behaviorism.
- It is predicated on the idea that behavior is either a reflex brought on by the combination of specific antecedent stimuli in the environment or a result of the individual's history, particularly reinforcement and punishment contingencies, in conjunction with their current state of motivation and controlling stimuli.
- Although most behaviorists acknowledge the significance of inheritance in affecting behavior, they place a greater emphasis on environmental factors.
- As a response to depth psychology and other traditional forms of psychology, which frequently struggled to make predictions that could be tested experimentally but were derived from earlier research in the late nineteenth century, such as when Edward Thorndike invented the law of effect, behaviorism emerged in the early 1900s.

Question:
In a science class, the teacher sets the room up with a variety of objects such as tubs of water, aluminum foil, and clay. The question on the board is: What makes objects float? Students enter the class and, in small groups, explore the materials. make decisions regarding what data to collect. and discuss the data's meaning. Students are urged to think, ask questions, and draw conclusions on their own. What theory drives this teacher's practices? Select one
A. Behaviorist/Behavioral
B. Humanistic
C. Cognitive
D. Nativist/Innatist
Frictional force from the friction caused between the course pavement and the rubber tire. It wears down the tire.
