Answer:
B. Two waves have displaced in opposite directions
Explanation:
Interference occurs when two waves meet at a point in space. When this occurs, two extreme conditions can occur:
- if the two waves are in phase (=displacement in the same direction), the amplitude of the resultant wave is equal to the sum of the amplitudes of the two waves:
A = A1 + A2
and this condition is called constructive interference
- if the two waves are in anti-phase (=displacement in opposite directions), the amplitude of the resultant wave is equal to the difference of the amplitudes of the two waves:
A = |A1 - A2|
and this condition is called destructive interference. Note that if A1=A2, the amplitude of the resultant wave is zero.
The direction of the angular velocity of the single wheel is the clockwise direction
<h3>Angular velocity</h3>
The angular velocity is the number of revolutions per second of the single wheel. It is given by ω = v/r where
- v = linear speed of the wheel and
- r = radius of the wheel.
<h3>Direction of the angular velocity of the single wheel</h3>
Since the wheels moves forward and the velocity of the wheel is always tangential to the wheel causing it to move forward, its angular velocity is in the clockwise direction
So, the direction of the angular velocity of the single wheel is the clockwise direction

Answer:
(a) 1/60
(b) Yes, it was unusual.
Explanation:
Number that went to the right field = 19
Number that went to the right center field = 18
Number that went to the center field = 12
Number that went to the left center field = 10
Number that went to the left field = 1
Total number of home runs = 60
(a) The probability that a randomly selected home run was hit to left field is
P(left field) = 1/60
(b) It was unusual because whenever a player hit a home run, it most times went to the right field,which is why the right field had the highest probability, 19/60.
On the other hand, it went to the left field the least number of times, which is why the left field had the least probability, 1/60.
So, it was unusual.
