Answer:
the center of the flower or the ovary
Answer:
- Amplitude = 5 cm (Heights)
- Wavelength (λ) = 40 cm
-
Wave speed (v) = 12 m/s (Approx)
- Time period (T) = 0.033 s (Approx)
- Maximum particle speed (V) = 9.43 m/s
Explanation:
1) Amplitude
Amplitude = 5 cm (Heights)
2) Wavelength (λ)
Wavelength (λ) = 40 cm
3) Wave speed
Wave speed (v) = √ t / μ
Wave speed (v) = √ 3.6 / [25x10⁻³]
Wave speed (v) = 12 m/s (Approx)
4) Time period (T)
Time period (T) = 1/f = (λ)/v
Time period (T) = 0.40m / 12
Time period (T) = 0.033 s (Approx)
5) Maximum particle speed (V)
Maximum particle speed (V) = Aw
Maximum particle speed (V) = [0.05x2x3.14] / 0.033
Maximum particle speed (V) = 9.43 m/s
Answer:
b) 105220.8 m
c) 65.38 miles
d) Kenneth's home
Explanation:
Velocity of Sarah = 31 m/s east
Velocity of Kenneth = 65 mph = 65×(1609.34/3600) m/s west
Time in seconds = 29.2×60 = 1752 s
Displacement = Velocity × time
Displacement of Sarah = 31×1752 = 54312 m
Displacement of Kenneth = 65×(1609.34/3600)×1752 = 50908.8 m
b) So, distance between their homes in meters is 54312 m + 50908.8 m = 105220.8 m
c) Converting to miles
Their homes are 65.38 miles apart
d) They met closer to Kenneth's house (50908.8 m)
Answer:
Explanation:
Magnitude of tension
= centripetal force
= m ω²R
= m (2π/T)² R , T is time period of revolution.
= .085 x (2 x 3.14 / .55)² x .84
= 9.3 N .
As the two spheres are brought into contact, the charge on the charged sphere is distributed equally between the two spheres. Now they both have the same charge. Because they have the same charge they are going to repel each other.
The two spheres are going to experience repulsion.
hope this helps :)
