John and Susan find a penny, and Susan says, "I bet you can't tell me what is on the penny". John's inability to describe the penny is an example of a failure to encode.
The ability to encode a piece of information is to be able to translate or explain the body of information at a later date or time. When John thinks about what is on the penny, he couldn't describe it because he never learned how to encode the information on the piece of the penny in the first place.
Retroactive interference is a process whereby fresh memories interfere with the recovery of old memories. This sort of interference has a retrograde impact rendering it more challenging to recall previously learned information.
On the other hand, proactive interference is a process whereby old memories interfere with the recovery of fresh new memories.
Therefore, we can conclude that since John has never learned what a penny looked like before, he doesn't have previous information about it. As such, the only correct option is (2)

Which is an example of static friction?
a. pulling a skier behind a boat
b. pushing a box that is at rest
c. braking a car going down a hill
d. driving a car up a hill
Answer:
static friction is developed between 2 surfaces in state of rest so i think answer is c.Even though the wheel is in motion, the patch of the tire in contact with the ground is stationary relative to the ground, so it is static rather than kinetic friction.
The static friction is the hindrance to an object which is trying to move from stationary state. Among the given options, the example for static friction is pushing the box that is at rest.
What is static friction?The friction that occurs when people attempt to move a stationary object on a surface without actually causing any relative motion between the body and the surface.
The static frictional force is self-regulating, which means that it will always be equivalent to and opposite to the force applied. Static friction is zero for an object at rest on a flat table.
Static friction creates an equal and opposite force that keeps the book at rest when you push horizontally with a small force.The static friction force increases to match the force as you push harder.
The maximum static friction force is eventually exceeded, and the book moves. Therefore, option B is correct.

=200Nm or joule.
What is the velocity of a freely falling object 10 seconds after it is released from rest?
Answer:
around 98 meters per second.
Explanation:
Instantaneous velocity can be found with a equation.
Vf=Vi+At
Since it fell and had no initial velocity the equation becomes
Vf=At
The Acceleration is 9.8 m/s^2
So the velocity of it fell for ten seconds is
Vf=9.8m/s^2 * 10
Vf= 98 m/s
A goose is flying due south at 20 km/hr, the goose is flying into a 15 km/hr due north wind. What is the gooses resultant velocity?
Answer:
5 km/hr due south
Explanation:
We need to subtract the two velocities due to the fact that they are in opposite directions (one due south and the other one due north). Then, for an observer located on earth, the goose will be flying at :
20 km/hr - 15 km/hr = 5 km/hr

Which of the following is a vector quantity?
A. 30 miles
B. 30 mph northwest
C. 55 m/s
D. 20 mph
Answer:
B) 30 mph northwest
Explanation: Vector quantities have both direction and magnitude. In this case the direction is northwest, and magnitude is 30 mph.
The following is a vector quantity, 30 mph northwest. Option B is correct.
What is a vector quantity?A vector quantity is a physical quantity that has both magnitude and direction. Examples of vector quantities include displacement, velocity, acceleration, force, and momentum.
In contrast, a scalar quantity is a physical quantity that has only magnitude and no direction associated with it. Examples of scalar quantities include speed, distance, mass, temperature, and time.
Here,
A vector quantity is a physical quantity that has both magnitude and direction. In this case, the magnitude is 30 mph and the direction is northwest, which makes it a vector quantity.
Option A is a scalar quantity because it only has a magnitude, but no direction associated with it. Option C is also a vector quantity because it has both magnitude and direction, but it is not given a direction in the question. Option D is a scalar quantity because it only has a magnitude.
Thus, the following is a vector quantity, 30 mph northwest. Option B is correct.

A 2 kg object is moving at a constant velocity of 15 m/s. What is its acceleration?
Answer:
The acceleration of the object is 0 m/s^2.
Explanation:
To solve this problem, we must remember that acceleration is equal to the change in velocity per unit time. Since we are given that the velocity is constant, this means it is unchanging, and the acceleration is therefore zero.

If an object weighs 20 N and is sitting on the floor without moving, what must be the normal force of the floor acting on the box?
20 N up
20 N down
10 N up
10 N down
Answer:
20 N up
Explanation:
Since the object on the floor is sitting still. Based on Newton's law of force. Objects must have equal reaction and force against each other for still objects. So the answer is 20 N up. Since the force are equal on both sides making the object not moving.

A frog falls from its rainforest tree. If we ignore wind resistance, (a) how much time does it take the frog to fall a distance of 12.0 m? (b) how fast is the frog falling at this point?
Answer:
Explanation:
a) Using the equation of motion
S = ut + 1/2gt²
S is the distance of fall
g is the acceleration due to gravity
t is the time taken
Given S = 12.0m, g = 9.81m/s^2, un= 0m/s
12 = 0+1/2(9.81)t²
12 = 4.905t²²²
t² = 12/4.905
t² = 2.446
t = √2.446
t = 1.56secs
b) To determine how fast is the frog falling at this point, we need to calculate the speed of the frog. Using the equaton v = u+gt
v = 0+9.81(1.56)
v = 15.34m/s
Hence the frog is falling at the rate of 15.34m/s

a cheerleader throws herself into the air with a velocity of 12 m/s at an angle of 75 degrees above the horizontal. what are the x- and y components of her velocity (show work)
Answer:
Vx = 3.10 [m/s]
Vy = 11.59 [m/s]
Explanation:
To solve this problem we must decompose the velocity vector by means of the angle on the horizontal.
v = 12 [m/s]
Vx = 12*cos (75) = 3.10 [m/s]
Vy = 12*sin (75) = 11.59 [m/s]
