Most objects move at a constant speed because of friction and acceleration. The constant speed keeps them in place, and keeps a balance.
Answer:
Explanation:
In closed organ pipe notes with odd harmonics are produced and in open organ pipe notes with all odd and even harmonics are produced. notes with frequencies 600, 800 and 1000 Hz are produced. These are 3 , 4 and 5 times 200 Hz. ie both odd and even times of 200 . So fundamental frequency appears to be 200 Hz. There is no note available between 800 and 1000. It also indicates that 200 Hz is the fundamental frequency and the pipe is open at both ends.
Answer:
1681714.28571 N/C
Yes it could exist
Explanation:
m = Mass of housefly = 12 m
q = Charge = 70 pC
g = Acceleration due to gravity = 9.81 m/s²
E = Electric field
When an object accumulates charge it means that it is gaining electrons making it negatively charged. This is the concept of static electricity.
Here, the electric force and the graviational force will balance each other
1681714.28571 N/C of electric field would be required to levitate
The direction of the electric field would be upwards vertically.
In air the critical value of electric field is 
which is more than the critical value of electric field in air. So, the electric field can exist.
