I would say D because when you think about tug-of-war, when someone on one side lets go, the people on the other team are able to pull the rope further to their side. So the rope would move right to the side of the red team because someone on the blue team let go therefore, there is less balancing the rope on the blue teams side.
The value of x is 40°. Because, we know that a half circle equals 180 degrees. A quarter circle equals 90 degrees. 50+40=90. The reflection area has the same degree amount, so the angle is 40 °. Let me know if this helps you!
Answer:
#_time = 7.5 10⁴ s
Explanation:
In order for the astronaut to be younger than the people on earth, it follows that the speed of light has a constant speed in vacuum (c = 3 108 m / s), therefore with the expressions of special relativity we have.
t =
where t_p is the person's own time in an immobile reference frame,

let's calculate
we assume that the speed of the space station is constant
t_ = 0.99998666657 s
therefore the time change is
Δt = t - t_p
Δt = 1 - 0.9998666657
Δt = 1.3333 10⁻⁵ s
this is the delay in each second, therefore we can use a direct rule of proportions. If Δt was delayed every second, how much second (#_time) is needed for a total delay of Δt = 1 s
#_time = 1 / Δt
#_time =
#_time = 7.5 10⁴ s
Answer:
3.47km/h with a direction of 67.8 degrees north of west.
Explanation:
First we need to calculate the displacement on the X axis, so:

then on the Y axis:

The magnitud of the displacement is given by:

and the angle:
that is 67.8 degrees north of west.
