The question for this problem would be the minimum headphone delay, in ms, that will cancel this noise.
The 200 Hz. period = (1/200) = 0.005 sec. It will need to be delayed by 1/2, so 0.005/2, that is = 0.0025 sec. So converting sec to ms, will give us the delay of:Delay = 2.5 ms.
Answer:
Option (C)
Explanation:
Recreational drugs are usually referred to those drugs or medicines that are legally or illegally used without any prescription given by the doctors. These drugs include marijuana, cocaine, alcohol, nicotine, heroin, and many others. These drugs provide relaxation for a shorter period of time, but using of these substances, it makes an individual addicted to drugs.
So, recreational drugs are one of the most potentially destructive ways to handle stress when a student is in college.
Thus, the correct answer is option (C).
Answer:
F = 3.15 N
Explanation:
Given electric charge, q = 6.3 μC
The magnitude of electric field, 
We need to find the electric force on the charge due to the electric field. The electric force is given by :
F = qE
Putting all the values,
So, the required force on the charge is 3.15 N.
