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.
Hope this helps!

Describe a ways car manufacturers try to reduce drag and why.
Aerodynamics is a way to reduce drag that uses car manufacturers.
What is aerodynamic ?
Aerodynamics is the motion of the air. airplane flies cause of aerodynamics.
Aerodynamics is the study of forces that are resulted by motion of the air.
To reduce the aerodynamic drag further, the manufacturers use character lines on the exteriors of the car's body right from its concept stage. These lines help the air to pass smoothly over the body and thus, reducing the air resistance.
cars have flat vertical face in front. When it moves through air, drag force directly proportional to the velocity applies on the car which opposes motion of the car. after studding aerodynamics when we make triangular like shape to the front body of the car, it cuts the air and front air goes from side of the car which reduces oppose to the motion, and car can have more speed.

Explanation:
A dog walks 21 m north and then walks 35 m west to bury a bone. What is the displacement of the dog?
Answer:
40.8 m North West.
Explanation:
Please see attached photo for diagram.
In the attached photo, R represent the displacement of the dog.
The displacement (R) of the dog can obtained by using the pythagoras theory as illustrated below:
R² = 35² + 21²
R² = 1225 + 441
R² = 1666
Take the square root of both side.
R = √1666
R = 40.8 m North West.
Therefore, the displacement of the dog is 40.8 m North West.

Explanation:
John and Susan find a penny, and Susan says, "I bet you can't tell me what is on the
penny". John thinks about it, and realizes he can't describe the penny. It appears that
John can't describe a penny because he never learned what one looked like in the
first place. John's inability to describe the penny is an example of
1) simply forgetting.
2) a failure to encode.
3) retroactive interference.
4) proactive interference.
Answer:

Explanation:

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)
