Answer: The wave is traveling in the - x direction.
Explanation: The parameter in a wave function determines the direction of the wave is "ωt"
Where ω = angular frequency(in hertz ) and t = time taken (in seconds)
The product of ωt = 2π which is angular displacement in radian.
A negative value of the of ωt means the wave is traveling in the negative direction.
Also a positive value of sin ωt means the wave is traveling in the positive direction

Look at the two of them, if you put them together the image is identical to that of the unknown sample.
Answer:
it Farther then it seems
Explanation:cause it value
Answer:
A
Explanation:
because you cannot seperate the matter duhhh hahha
Answer:
Explanation:
There is no external force applied, therefore there is a moment's preservation throughout the trajectory.
<em>Initial momentum = Final momentum. </em>
The total mass is equal to
Where,
mass of ship
mass of fuell expeled.
As the moment is conserved we have,
Where,
Velocity of fuel
Velocity of Space Ship
Solving and re-arrange to 
we have,
Where c is the speed of light.
Therefore the ship be moving with speed
