Answer:
Speed of the wave in the string will be 3.2 m/sec
Explanation:
We have given frequency in the string fixed at both ends is 80 Hz
Distance between adjacent antipodes is 20 cm
We know that distance between two adjacent anti nodes is equal to half of the wavelength
So \frac{\lambda }{2}=20cm
2
λ
=20cm
\lambda =40cmλ=40cm
We have to find the speed of the wave in the string
Speed is equal to v=\lambda f=0.04\times 80=3.2m/secv=λf=0.04×80=3.2m/sec
So speed of the wave in the string will be 3.2 m/sec
To find this you will use the y2-y1/x2-x1
(-7/2, -3) (-5, 5/2)
x1 y1 x2 y2
5/2 - (-7/2)
_________
-5-(-3)
12/2=6
-2
6/-2= -3
slope= -3
Answer:
1/6
Step-by-step explanation:
Since the die has 6 sides that are all equally likely to be landed on, the probability of landing on 2 is 1/6, as there is one "favorable" outcome and 6 total outcomes. Hope this helps!
Answer:
NOT VERY LIKELY
Step-by-step explanation:
• 1/2 OF THE CLASS TOOK FORM A
• 1/2 = 50%
• THE CHANCE CANNOT BE OVER 50%
• 39% OUT OF 50% PASSED
• 50% - 39% = 11%
• THE ANSWER IS NOT VERY LIKELY
Answer:
Since line l is parallel to line M, we know that angle 1 is congruent to angle 3. In that case, since we know that angle 3 in congruent to angle 7, we line a also has to be parallel to line b.
