We will calculate the synodic period, as it is the time it takes for the object to reappear at the same point in the sky with respect to the sun, when viewed from Earth. For this problem we will apply the concepts related to the orbital period ( Kepler's Third Law ) which is determined as
Where,
r = Radius/Distance
G = Gravitational Universal Constant
m = Mass of the object
Replacing,
For the sound wave passing through regions of the ocean with varying density, longer wavelengths correspond to greater density of the water.
<h3>What is effect of density of a medium on wavelength of a wave?</h3>
The density of a medium is directly proportional to the wavelength of a wave.
The higher the density of the medium, the longer the wavelength of a wave.
Therefore, for a sound wave passing through regions of the ocean with varying density, longer wavelengths correspond to greater density of the water.

Answer:
TRANSMISSION-
visible light meets clear glass
-cell phone signals pass through walls-
Explanation:
Transmission means that light actually passes through an object. Light in this context refers to electromagnetic radiation. All the radiation found in the electromagnetic spectrum are generally called light. This includes radio waves used in telecommunication.
White light is transmitted through glass because it actually passes through the glass.
Passage of cell phone signals through walls is also a typical example of transmission of light.
Explanation:
When there is frictional force distance traveled by the arrow is s = (v^2)/(2μ_kg)
v= velocity of the object
μ_k = kinetic friction coefficient
g= acc. due to gravity.
as distance is proportional to square of the speed therefore the faster arrow penetrate a distance 4 times the distance penetrate by slower arrow.
Answer:
a) 12.0 m/s
b) 9.81 m/s in the downward direction
Explanation:
The initial velocity of the ball in the horizontal direction = 12.0 m/s
a) The velocity of the baseball in the x-direction remains the same therefore, we have;
The velocity of the ball in the x-direction (horizontal direction) after 1 second = 12.0 m/s because there is no net acceleration in the horizontal direction
b) The velocity in the y-direction is given by the following kinematic equation;
v = u - g × t
Where;
v = The final vertical velocity of the ball after t seconds
u = The initial vertical velocity = 0
g = The acceleration due to gravity = 9.81 m/s²
t = The time taken in motion = 1.00 s
Substituting the values gives;
v = 0 - 9.81 m/s² × 1.00 s = -9.81 m/s
v = -9.81 m/s
The vertical velocity of the ball after 1.00 second = -9.81 m/s which is 9.81 m/s downwards.
