Answer:
The drift velocity of the electrons in this case is c) 5.52 x 10-4 m/s
Explanation:
Hi
First of all, we need to find the volume occupied by 63.3g of copper, so
, then if we assume each atom of copper contributes with one free electron to the material body
.
Finally, we apply
, where A is area so,
, thus
.
As we can see c. 5.52 x 10-4 m/s is the nearest one.
Answer: Negative acceleration occurs when an object slows down in the positive direction.
Positive acceleration occurs when an object speeds up in the positive direction.
Explanation: Acceleration can be positive or negative. A negative acceleration is also known as deceleration. And deceleration occurs when an object is coming to rest. While acceleration simply means that an object is Speeding up.
Negative acceleration occurs when an object slows down in the positive direction.
Positive acceleration occurs when an object speeds up in the positive direction.
