Answer:
a) For P: 
For Q: 
b) For P:
for Q:
c) As the distance from the axis increases then speed increases too.
Explanation:
a) Assuming constant angular acceleration we can find the angular speed of the wheel dividing the angular displacement θ between time of rotation:
One rotation is 360 degrees or 2π radians, so θ=2π
Angular acceleration is at every point on the wheel, but speed (tangential speed) is different and depends on the position (R) respect the rotation axis, the equation that relates angular speed and speed is:
for P:
for Q:
b) Centripetal acceleration is:
for P:
for Q:
c) As seen on a) speed and distance from axis is because ω is constant the if R increases then v increases too.
Well, those are good ones. Now how about a <u><em>thermometer</em></u> to <em>measure the temperature</em> ?
Answer:
Explanation:
From the question we are told that:
Speed of light 
Generally the equation for Average Speed is mathematically given by
Where
d=Distance between the Earth and the sun
Therefore
Since m and n is given in the form of
Therefore
Answer:
Earth and Venus has similar size, mass and density. Both have a very similar composition, But atmosphere of Venus is composed only of carbon dioxide is not similar to Earth.
Explanation:
my mind
My best guess would be sun because it is bright but is surrounded by shadows on all sides.
