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:
Explanation:
given data
Radius of sphere 3.0 cm
charge Q = 2.0 m C
We know that maximum electric field is given as
electric field inside the sphere can be determine by using below relation
The concept of a black hole seem reasonable to me because of its valid and authentic evidences.
<h3>What are the causes, characteristics, and major features of black holes?</h3>
A black hole is a region in space where light is unable to escape due to strong gravitation force. The strong gravity is formed because matter has been pressed into a tiny space. This compression occurs at the end of a star's life. Some black holes are formed when a stars die.
So we can conclude that the concept of a black hole seem reasonable to me because of its valid and authentic evidences.

<h3>Answer;</h3>
-Temperature
<h3><u>Explanation;</u></h3>
- Sound is a type of mechanical wave, which means it requires a material medium for transmission. It results from the vibration of particles.
- The speed of sound in mediums varies depending on the property of the medium and a number of other factors which includes; temperature, pressure, and humidity.
- Temperature increases the speed of sound wave as particles at higher temperatures tend to possess more energy and thus they will vibrate faster and thus the sound wave will travel faster.
The answer is the troposphere you breathe in the air
