We will use formula for the orbital velocity of Venus, which is v = 35.02 km/s.
An average distance to the Sun ( In kilometers ) is:
R = 0.723 * 149,579,871 km= 108,150,260 km.
Than we will calculate the orbital period ( T ).
v = 2 π R / T
T = 2 π R / v
T = 2 * 3.14 * 108,150,260 km / 126,072 km/s
T = 5389.75 s ≈ <span>224.5 days
The orbital period of Venus is approximately 224.5 days.</span>
Answer:3.185KHz
Explanation:
Where
Length (L) = 2.7cm
Speed (V) = 344m/s
Wavelength of the fundamental standing wave: λ = 4L
λ = 4L
Frequency is the rate per second of a vibration constituting a wave.
Frequency is given as:
F= v/ λ
Therefore,
Frequency= v/4λ
Frequency = 1×(344m/s)/4×(2.7cm)
Convert centimetre to meter
100cm= 1m
Convert Hz to kiloHz
1000Hz= 1kHz
Frequency= 3.185KHz
Answer:
-2R
Explanation:
The focal length can be calculated using this formula
1/f = (n1/n2-1)(1/r1-1/r2)
1/f = (1/1.33-1)(1/r + 1/r)
= -0.133/1.33(2/R)
F = -2R
The focal length is this
Answer:
variable
Explanation:
Globular clusters is defined as collection of numerous star that revolve around the galaxy core. they are so bound to each other that they formed spherical shape. This boundness among the star is due to gravity. The main characteristics of globular cluster is that they contain high density of star at center.
Every galaxy consist of various number of globular cluster and even milky way consist of 125 to 200 cluster
where:
F - force
m - mass
a - acceleration
We transform this formula to get a:
