I'm pretty sure that the "block" of which you speak is one in a pattern
of them that covers the drawing you have of the rectangle, and now
I need to explain something to you:
The REASON for printing that drawing next to the question that you
partially copied is that the drawing has information that's needed to
answer the question with, and rather than repeat all that information
in the question, it just says "LOOK AT THE DRAWING !"
In fact, the whole point of the question may not be just to remind you of
what "perimeter" means. It's more likely that the purpose of this problem
is to make you pick the information you need off of a drawing.
Either way, if you'll kind of "read between the lines" of the part of the
question that you DID copy, it should be pretty obvious to you that nobody's
going nowhere in the direction of a solution without SEEing the drawing.
So my bottom-line conclusion regarding a solution for this problem is:
Not possible with the given information.
Answer:
Explanation:
It is given that the ball is lodged in a hole in the floor of merry-go-round that is running at a constant speed.
Now the ball is moving a vertical circular motion
The position of the ball changes w.r.t to the center as it moves in a circular path i.e. vectorially it changes but its magnitude will remain the same.
The velocity of the ball is the same as merry-go-round so its magnitude remains the same but its direction will change continuously.
As the ball is moving in a circular path so a centripetal acceleration will acts towards the center so its value will be continuously changing.
Answer:
Increase the amplitude
Explanation:
The energy conveyed by a wave is directly proportional to the square of its amplitude. Thus; E ∝ A²
This means that increasing the amplitude will lead to an increase in the energy.
Now, the amplitude of a wave is the height of a wave from it's highest point known as the peak, to the lowest point on the wave known as the trough whereas wavelength refers to the length of a wave from one peak to the next.
This means that increasing the amplitude has no effect on the wavelength.
Answer:
C = (7 + 8) i + (5 - 1) j adding vectors
C = 15 i + 4 j
theta = arctan (4 / 15) = 14.9 deg
Note that this is the same as adding x and y components
