The vector, the x-component and the y-component form a rectangle triangle where the vector is the hypothenuse and the x and y components are the two sides.
Calling
the angle between the vector and the horizontal direction (x), the two sides are related to
by
where vy and vx are the two components on the y- and x-axis. Using vx=10 and vy=3 we find
And so the angle is
Yes, that is true. I hoped I helped!
Answer:
Saturn is the answer of your question
Answer:
Red has the longest wavelength among all the visible colors of light.
Explanation:
Visible light is the only electromagnetic radiations which can be seen by human eye. When white visible light passes through a prism it breaks down into 7 distinctive colors of rainbow.
These are red, orange, yellow, green blue, indigo and violet.
Red has the longest wavelength of around 700 nano meters with violet has the shortest wavelength of 380 nano meters.
The time 
it takes for the key to fall 44 m is
(notice I'm taking the downward direction to be positive)
The boat, moving at a presumably constant speed, then has 3.0 s to travel 19 m to the point of impact, which means its speed must be
