Period of a simple pendulum = 2π √(L/G)
(360s/100) = 2π √(1.2m/G)
1.8s / π = √1.2m / √G
√G · (1.8s/π) = √1.2m
√G = (π · √1.2m) / 1.8s
Square each side:
G = π² · 1.2m / 3.24 s²
G = (1.2 · π² / 3.24) m/s²
G = 3.66 m/s²
So I just went and looked up Mars gravity. Floogle says it's 3.711 m/s² there.
That seems awfully close ... only 1.4% greater than our astronauts measured.
You don't suppose . . . . .
Answer:
The wavelength is
The frequency is
Explanation:
Given that,
Distance between slits d= 0.044 mm
Distance between fringe and center of the pattern y= 8.1 cm
Distance between slits and fringes D = 6.40 m
We need to calculate the wavelength
For constructive interference
Put the value into the formula
We need to calculate the frequency
Using formula of frequency
Hence, The wavelength is
The frequency is
Answer:
Cumulus Congestus & Cumulonimbus Clouds
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 .
