The cat fell 1.0 m from the ground.
Using the formula
Here, 
Solving for t, the time it spent in the air is
The cat does not accelerate along the horizontal, so it has constant horizontal velocity. Since it strikes the floor 2.2 m from the table, then
The answer is D. As the ambulance gets closer, the sound waves are compressed relative to the person; so the frequency increases.
Answer:
The the angle between the axis of polarization of the light and the transmission axis of the analyzer is 52⁰.
Explanation:
Given;
I₀ as incident light intensity
The intensity of a linearly polarized light passing through a polarizer is given by Malus' law:
I = I₀Cos²θ
where;
I is the intensity after passing through the analyzer
θ is the the angle between the axis of polarization of the light and the transmission axis of the analyzer.
If 38% of the total intensity is transmitted, then I = 38% of I₀ = 0.38I₀
0.38I₀ = I₀Cos²θ
0.38 = Cos²θ
Cosθ = √0.38
Cosθ = 0.6164
θ = Cos⁻¹ (0.6164)
θ = 51.95° = 52⁰
Therefore, the angle between the axis of polarization of the light and the transmission axis of the analyzer to allow 38% of the total intensity to be transmitted is 52⁰.
Answer:
8 m³
282.3 ft³
Explanation:
The volume of each box is width times length times depth:
V = (1 m) (2 m) (1 m)
V = 2 m³
There are four boxes, so the total volume is:
4V = 8 m³
Converting to cubic feet:
8 m³ × (3.28 ft / m)³
= 282.3 ft³
The correct answer is: Anti-nodes.
Explanation:
When the interference between the two waves is constructive and the <span>points on the wave that undergo the maximum displacement during each vibrational cycle </span><span>of the standing wave </span>back and forth. Those points are called anti-nodes. Hence, in the case of sound waves, interference creates standing waves, and the points on the medium that move up and down with the highest amplitudes are called anti-nodes.
