False
If all other factors, such as medium, are kept the same, longitudinal waves tend to be stronger.
Answer:
the googles are 5.3 m from the edge
Explanation:
Given that
depth of pool , d = 3.2 m
Now, let i be the angle of incidence
a laser pointer 0.90 m above the edge of the pool and laser beam enters the water 2.2 m from the edge
⇒tan i = 2.2/0.9
solving we get
i = 67.8°
Using snell's law ,
n1 ×sin(i) = n2 ×sin(r)
n1= refractive index of 1st medium= 1
n2= refractive index of 2nd medium = 1.33
r= angle of reflection
therefore,
r = 44.1°
Now,
distance of googles = 2.2 + d×tan(r)
distance of googles = 2.2 + 3.2×tan(44.1)
distance of googles = 5.3 m
the googles are 5.3 m from the edge
Acceleration i believe is the answer
The acceleration of the mass down the plane is determined as (4mg sinθ)/(3mr²).
<h3>Conservation of angular momentum</h3>
The acceleration of the mass down the plane is determined by applying the principle of conservation of angular momentum.
Fr = Iα
where;
- F is weight of the object parallel to the plane
- r is the radius of the flywheel
- I is moment of inertia
- α is angular acceleration
(mg sinθ)r = Iα
(mg sinθ)r = I(ar)
(mg sinθ) = I(a)
Thus, the acceleration of the mass down the plane is determined as (4mg sinθ)/(3mr²).
