Explanation:
T = 2π √(L / g)
1.0 s = 2π √(L / 19.6 m/s²)
L = 0.50 m
Answer:
C
Explanation:
Constellations are stellar patterns which are made out of bright stars which appears close to each other and can form a recognisable pattern.
But that does not mean these stars are actually close to each other. The sky that we see from Earth appears as a 2D representation of a 3D Space. If you look in a particular direction in sky you will see all the stars in that direction irrespective of their actual distance from the Earth and hence these stars can be practically very far from each other too.
Answer:
<em>At t=T/2 the angular speed equals to its average angular speed </em>
Explanation:
<u>Angular Motion</u>
Let w be the angular speed of a rotating object, its angular acceleration, and T the time the acceleration is acting upon the object. The basic formula for the angular motion is
We are told the initial speed is zero, so
The average angular speed from t=0 to t=T can be found by
This value is reached at a certain time we need to compute, knowing that
Or equivalently
Simplifying we have
At t=T/2 the angular speed equals to its average angular speed
