A 300 g bird is flying along at 6.0 m/s and sees a 10 g insect heading straight towards it with a speed of 30 m/s. The bird open
Gelneren [198K]

Answer:

(a): The bird speed after swallowing the insect is V= 4.83 m/s

(b): The impulse on the bird is I= 0.3 kg m/s

(c): The force between the bird and the insect is F= 20 N

Explanation:

ma= 0.3 kg

va= 6 m/s

mb= 0.01kg

vb= 30 m/s

(ma*va - mb*vb) / (ma+mb) = V

V= 4.83 m/s (a)

I= mb * vb

I= 0.3 kg m/s  (b)

F*t= I

F= I/t

F= 20 N (c)

How do professional bicycle riders reduce friction. Name two ways.<br> Thx
wlad13 [49]
A well maintained bicycle is key.  Oil the chain so that it's less likely to get hung up.  It will have a smoother flow.  Another could be in their clothing.  Notice they usually wear good fitting clothing?  I believe the more from fitting pants help clothing friction.  Another way could be keeping the tires well inflated so that the tires aren't dragging.  Rolling along smoothly on properly inflated tires seems like a must.  Get a few more answers along with mine, so that you have a variety to choose from.

Planar waves from a monochromatic light source are normally incident on a circular obstacle, which casts a shadow on a screen po
Svetradugi [14.3K]

Answer:

correct  is the A

Explanation:

The light is a wave that has travels from two different places, each side of the circular obstacle, so an interference process must be given, which is described by the expression

                a sin θ  = m λ

Where a is the size of the slit, λ the wavelength and m an integer that indicates the order of diffraction.

In the case of the central point, the difference in the optical path of each ray stop is zero, which implies that in some it is also zero, so the waves are in phase for this point and a bright spot must be seen in the center.

When reviewing the answer the correct one is the A
