Answer:

Explanation:
The acceleration of an object is calculated as

where
v is the final velocity
u is the initial velocity
t is the time taken for the velocity to change from u to v
For the rocket in this problem:
u = 0 (it starts from rest)
v = 440 m/s is the final velocity
t = 2.20 is the time taken
Substituting,

Answer:
180 meters
Explanation:
Josh walks 6 meters to the right and the 6 meters back. This means that in one time, Josh walks a total distance of 6+6 = 12 meters
Now, we are given that Josh walks this same distance 15 times.
Therefore, we will multiply this distance by 15 to get the total distance that he walks as follows:
Total distance = 12*15 = 180 meters
Based on the above calculations, Josh walks 180 meters over the course of the class

As we know that equivalent resistance of a capacitor for an AC circuit is given as

so here for an AC circuit capacitor will provide less resistance to AC component of the current
While for DC as we know it has ZERO frequency
so we will have large resistance
so here we will have to use capacitor as a filter circuit which will separate AC component of current from the DC current
So correct answer will be
CAPACITOR
