To solve this problem we will use the general system of simple harmonic movement and compare this structure with the given value. From this equation we can find the phase. Our given value is
Data:
t = 2 s
The expression given from the theory for the harmonic movement is:
Where,
= Phase Angle
A = Amplitude
Here the Phase angle is given as
Comparing we have,
Replacing the time of t, we have that
Therefore the phase of motion at t=2s is
Because acceleration was constant throughout the slide, we can show the slide lasted
Also because accleration was constant, we know the average velocity of the book was
Average velocity is also given by
so the width of the desk must have been
which means C is the most likely answer.
Answer:
UY Scuti is slightly larger than VY Canis Majoris
Explanation:
These stars are millions of miles away and cannot be seen by the naked eye.
Beetlejuice is another large star that can be seen by the eye.
Answer:
f = 8 %
Explanation:
given,
density of body of fish = 1080 kg/m³
density of air = 1.2 Kg/m³
density of water = 1000 kg/m²
to protect the fish from sinking volume should increased by the factor f
density of fish + density of water x increase factor = volume changes in water
1080 +f x 1.2 =(1 + f ) x 1000
1080 + f x 1.2 = 1000 + 1000 f
998.8 f = 80
f = 0.0800
f = 8 %
the volume increase factor of fish will be equal to f = 8 %
