Answer:
0.76m
Explanation:
Given data
Frequency= 230Hz
speed= 350m/s
Since we are told that the frequency is the fundamental frequency n= 1
For a standing wave
Fn= nv/2L
n= 1
230= 1*350/2*L
230= 350/2L
cross multiply
2L= 350/230
2L=1.521
L=1.521/2
L=0.76m
Hence the length is 0.76m
Given what we know, we can confirm that genetic material is not known to absorb light originating from an infrared or microwave radio source.
<h3>What light does genetic material absorb?</h3>
- Genetic material is known to absorb UV light.
- This represents ultraviolet light.
- UV light is electromagnetic radiation, and the primary source of UV light that we are exposed to is the sun.
Therefore, given that the only form of light listed that genetic material is known to absorb is that of Ultraviolet or UV light, we can confirm that the answer to the question proposed is infrared and microwave radio light.

A contour line represents a certain vertical height above the contour line shown. They are means of representing 3D hills and moutains on 2D paper.
Answer:
7.6*10^4J
Explanation:
Given that m=95kg
Final velocity= 40m/s
Using W=0.5 m (square of (final velocity) - square of (initial velocity))
= 0.5 * 95 * Squared of (40)
= 7.6*10^4J
Answer:
Explanation:
Given
Acceleration a = 1.0m/s²
Displacement S = 1.0m
Required
Time t taken by the leaf to displace
Using the equation of motion
S = ut+1/2at²
Substitute
1.0 = 0+1/2(1)t²
1 = t²/2
Cross multiply
t² = 2
t = ±√2
t = 1.41secs
It takes the leaf to 1.41s to displace by 1m upward
