Answer:
v = 16.58 m/s
Explanation:
Given that,
Mass of a bird, m = 1.6 kg
Kinetic energy of the bird, K = 220 J
We need to find the speed of the bird. The formula for the kinetic energy is given by :

Where
v is the speed of the bird
So,

Put all the values,

So, the speed of the bird is equal to 16.58 m/s.
Answer:

brooo like ittttttttttttt
Answers:
a) 222.22 m/s
b) 800.00 km/h
Explanation:
The speed of a wave is given by the following equation:
Where:
is the speed
is the frequency, which has an inverse relation with the period 
is the wavelength
Solving with the given units:
This is the speed of the wave in km/h
Transforming this speed to m/s:

This is the speed of the wave in m/s
<span>So the question is how does heat prefer to remain and to unscramble the letters ONMFRIU. The unscrambled letters mean: UNIFORM. The heat likes to remain uniform because thermodynamic systems always tend to reach thermal equilybrium after some period of time that is specific for each system. </span>

Explanation:
a) in solving the first question, we will be choosing a spherical ball of radius 1 m, Therefore the width of the object is the diameter = 2m.
b)Given that and according to the question, the radius of the electron's orbit = 1x105 x radius of the object = 1x105 x1 = 1x105 m
