Answer:
α = π/3
β = π/6
Explanation:
Use arc length equation to find the sum of the angles.
s = rθ
π/20 m = (0.1 m) (α + β)
π/2 = α + β
Draw a free body diagram for each sphere. Both spheres have three forces acting on them:
Weight force mg pulling down,
Normal force N pushing perpendicular to the surface,
and tension force T pulling tangential to the surface.
Sum of forces on A in the tangential direction:
∑F = ma
T − m₁g sin α = 0
T = m₁g sin α
Sum of forces on B in the tangential direction:
∑F = ma
T − m₂g sin β = 0
T = m₂g sin β
Substituting:
m₁g sin α = m₂g sin β
m₁ sin α = m₂ sin β
(1 kg) sin α = (√3 kg) sin (π/2 − α)
1 sin α = √3 cos α
tan α = √3
α = π/3
β = π/6
Answer:
Most wild races do not understand how the galaxy works. Let's see how well humans interpret a simple observation. The fact that we find O and B stars in the disk of our galaxy but not in the halo suggests that if there is knowledge about the galaxy, because it is known that there are stars, planets, black holes, halos, however there is still no the necessary technology, for the investigation and the refutation of the theories that currently exist on the theme of the galaxy.
Answer: Water is the world's most common acid and base.
Explanation:
Since, it is given that one hand completes 3.19 vibrations in 8.46 sec. Therefore, in one second the number of vibrations will be as follows.
= 0.377 vibrations
Hence, frequency (f) = 0.38 Hz
Now, formula to calculate the speed is as follows.
v = 
or, 
= 
= 1.57 cm
Thus, we can conclude that the wavelength is 1.57 cm.
Here are the answers to the given question above.
