Answer:
Resultant amplitude is 0.53 m.
Explanation:
Amplitude is defined as the maximum displacement of wave particles from their respective mean positions.
The resulting amplitude of any two waves is given by the relation :
A =
Here, A is resultant amplitude, A₁ and A₂ are the amplitudes of two waves respectively and x is the difference in phase angle of the two waves.
According to the problem, A₁ is 0.4 m , A₂ is 0.23 m and x is zero. So, the above equation becomes,
A =
A =
A = 0.63 m
Answer: B, Microwaves reach a cell tower, then fiber optic cables send the signal to a cell tower near the person you are calling.
Explanation:
That you won't slip while walking because you will have more balance and support
Answer:
B. 0.50 meters/second^2
Explanation:
Given:
- mass of table (m) = 10.0 kg
- Eli's force (F1) = 120 N
- Andy's force (F2) = -125 N
Arranging Formulas and Substituting Values, Part 1:
- F = F1 + F2
- F = 120 + (-125)
- F = -5 N
- The -5 means that the table will move along the direction of the force applied by Andy.
Arranging Formulas and Substituting Values, Part 2:
- m * a = F
- a = F / M
- a = -5 / 10.0 kg
- a = -0.5 m/s^2
