Answer:
Part a)
Part b)
Explanation:
Part a)
mass of the Falcon bird is given as
initial speed of the bird is
final speed of the bird is given as
(opposite direction)
So here the impulse given by falcon bird is given as
now the final momentum of Raven bird in perpendicular direction is given as
now the change in the angle of the raven bird is given as
Part b)
Final speed of the raven bird is given as
Answer:
<em>d) Microwave ovens emit in the same frequency band as some wireless Internet devices.</em>
<em></em>
Explanation:
Microwave are radio waves of short wavelength, from about 10 centimetres to one millimetre, in the Super High Frequency and the Extremely High Frequency bands. Microwaves can penetrate into materials and deposit their energy below the surface which is why is is used in microwave heating found in microwave oven. Transmission of data sometimes involves the use of microwaves to send and receive information over a long distance. Microwaves are the mainly used in radar, used for satellite communication, and wireless networking technologies such as Wi-Fi.
Behavioral adaptations are the things organisms do to survive. So yes, it's true!
Answer:
Explanation:
As we know that the wavelength of light is given by
now we know that
now from above equation we know
now the diameter of the bead is given as
Now total number of wavelengths that travel in the bead is given as
