Explanation:
Given that, two successive resonant frequencies for an open ended organ pipe (open at both ends) are 801 Hz and 890 Hz.
(a) The frequency in case of organ pipe open at both ends is given by :
L is the length of the pipe
if f = 801 Hz
.........(2)
If f = 890 Hz for (n+1)
So, .........(2)
Dividing equation (1) and (2) we get:
On solving,
n = 9
(b) The speed of sound in air, v = 343 m/s
L = 1.92 meters
Hence, this is the required solution.
Answer:
1020
.00
1040.4
0
1061,208
1082.43
Explanation:
In this exercise we must calculate interest and add it to capital
2% of 1000
first month
interest = 1000 2/100
odds1 = 1020
second month
capital 1020
interest = 1020 0.02 = 20.4
odds2 = 1040.4
third month
capital = 1040.4
interest = 1040.4 0.02 = 20.808
odds3 = 1061,208
fourth month
capital = 1061,208
interest = 1061.208 0.02 = 21.22
odds = 1082.43
D I think opposite is negative towards positive if I remember
Answer:
Real and inverted
Explanation:
Magnification of a lens is defined as the ratio of the height of the image to the height of the object.
Where
h' is the height of image
h is the height of the object
It is also defined as the ratio of image distance to the object distance.
Here, m = -0.6
Negative sign shows the image is inverted. So, the formed image will be real and inverted.
Answer:
Explanation:
Given that,
Force acting, F = 6N
The radius of the path,
Angle,
We need to find the amount of torque acting on the object. The formula for torque is given by :
So, the required torque is equal to 0.03 N-m.
