Answer:
6.97 E 16
Explanation:
Frequency is a function of velocity of light to it's wavelength.
Mathematically written as
F = Velocity / wavelength
Velocity of light = 3 x 10^8
Wavelength =430 nm =430 x 10^-9 m
converting wavelength from nanaometer to meter we divide by 10^9
Frequency = (3 x 10^8)/(430 x10^-9) =6.97 E 16
Answer:
The period of the satellite is 12.05 s.
Explanation:
The period of the satellite can be determined by;
T = 
where: T is the period, r is the radius of the orbit, G is the gravitation constant and M is the mass of the Earth.
Given that: r = 6 x (6.38 x 
) = 38.28 x m, M = 5.98 x 
kg, G = 6.673 x 
N
/ 
.
Therefore,
T = 
= 
= 
= 12.0463
T = 12.05 s
The period of the satellite is 12.05 s.
Answer:
The strength of gravity on the moon is 
.
Explanation:
We have,
Weight of the backpack, W = 9.2 N
Mass, m = 5 kg
It is required to find the strength of gravity on the moon. Weight of an object is given by :
W = mg
g is strength of gravity on the Moon
So, the strength of gravity on the moon is .
Answer:
The cha-cha-cha, is a dance of Cuban origin. It is danced to the music of the same name introduced by Cuban composer and violinist Enrique Jorrin in the early 1950s. This rhythm was developed from the danzón-mambo
Answer:
nothing
Explanation:If you ride a bike around the block and return to the exact point where you started, your displacement is zero.
By definition, displacement involves changing an object from its original position. No matter how far or for how long a body moves, if it returns to the position it started from, it has not been displaced at all. This means that the body has zero displacements.
