Answer: The question is incomplete or missing details. here is the remaining part of the question ;
1. impossible to determine
2. half of Isaac’s
3. the same as Isaac’s
4. twice Isaac’s
The angular speed of feng will be the same as that of Isaac. Hence the answer is option 3
Explanation:
Since we have been told that both feng and isaac are riding on a merry go round i.e in a circular motion, irrespective of how fast one ride above the other, the angular speed will be constant since they are riding on a merry go round, as such both feng and isaac will maintain equal angular speed, hence the angular speed of feng will be the same as that of Isaac.
Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.
Answer:
The medium for the sound waves produced by the dog barking is the air
Explanation:
Sound waves are a form of mechanical waves such that it moves from one point to another by the vibration, back and forth of the medium particles from one layer to the next, thereby the particles of the medium remain in the same location and only the wave energy is propagated
The medium which has particles that vibrate back and forth in order to transmit the barking of the dog is the air.
Answer:
It will take 0.46 seconds to reach home plate by ball.
Explanation:
Answer:
The new force between the charges becomes double of the initial force.
Explanation:
The force acting between charge particles is given by :
k is electrostatic constant
r is distance between charges
If one of the charges are doubled, then, q₁ = 2q₁
The new force becomes,
So, the new force between the charges becomes double of the initial force.
