Answer:
increasing more mass will decrease the acceleration of the skateboarder.
Explanation:
Newton's Second Law states whenever an unbalanced force is applied on an object, it produces an acceleration in the object in the direction of force. This acceleration is directly proportional to force by inversely proportional to mass.
where,
F = Force
a = acceleration
m = mass
If we consider force applied on the skateboarder, then the acceleration is inversely proportional to mass, only.

<u>Therefore, increasing more mass will decrease the acceleration of the skateboarder.</u>
We expect the last colour of the sunset to be on the red end of the visible spectrum because of the dispersion of light. Due to the particles present in the atmosphere, the light rays undergo scattering and the light of shorter wavelengths like blue gets dissipated but light rays of longer wavelengths travel long distances without getting dissipated.
Dispersion of light is the phenomenon in which the light from the sun is split into its constituent colours which are Violet, Indigo, Blue, Green, Yellow, Orange, and Red when it passes through a prism or due to the particles present in the earth's atmosphere.

Check Explanation
Explanation:
Let the speed of the drone relative to earth be u = ?
Let the speed of the drone relative to the starship be u' = 0.5c
Let the speed of the starship relative to earth be v = 0.8c
In the theory of relativity,
The 3 speeds are related thus
u = (u' + v)/[1 + (u'v/c²)]
u = (0.5c + 0.8c)[1 + ((0.8c × 0.5c)/c²)]
u = 1.3c/[1 + (0.4c²/c²)]
u = 1.3c/1.4 = 0.9286 c = 0.93 c = 93% c
The tension in the cable when it is at angle of 30° to the vertical is <u>86.6 lb.</u>
refer to the attached diagram.
The cable has a weight <em>W</em> attached to it and it is at an angle θ 30° to the vertical.
Resolve the weight <em>W</em> into two components W cos θ opposite to the tension <em>T</em> and W sinθ perpendicular to it, as shown in the diagram.
Apply the condition for equilibrium along the direction in which the tension acts.
Substitute 100 lbs for <em>W</em> and 30° for θ.
Thus the tension in the cable when it is at an angle 30° to the vertical is <u>86.6 lb.</u>
solution:
The first step is that both the top and bottom forces cancel out because if you remember that each atom has either a +e or -e, you can conclude that since they are at the same length, that they cancel.
So the only part you really need to worry about is the middle one with the distance of .300 nm. From there, you find the distance between both bonds of N-H (one is....11 while the other is .19).
Then for each one you use 
If you calculate both correctly, you will get
Then just add the two and you got the answer!
