Answer:
Magnification will be equal to 3
Explanation:
We have given focal length of the converging lens 
Focal length of the diverging lens 
Object is placed 40 cm to the length of the converging lens d = 40 cm
Combination of the focal length will be equal to


F = 60 cm
So combination of the focal length will be 60 cm
Magnification is given by

So magnification will be equal to 3
Answer:
0.006<357<700.003<6010<9256.0<9520.00
Answer:
a blaring trumpet is sound energy
Explanation:
Answer:
it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.
Explanation:
Magnetic field is along z axis while velocity is in x-z plane
so we will have

so here we can say

so we will have

so here the net force on the charge is perpendicular to its x directional velocity along - Y direction
So due to this component of motion it will move along a circle while other component of the motion will remain uniform always
So here it is combination of two parts
1) Uniform circular motion
2) Uniform motion
So we can say that it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.
The distance that is not a wavelength in the image is C to E.
<h3>What is wavelength?</h3>
Wavelength is the distance between two successive crests or two successive trough or crest to trough.
It is also the distance over which the wave's shape repeats.
Based on the image, the following are wavelengths;
- A to E, this is wavelength because it is between a crest and a trough.
- B to F, this is wavelength because it is between two successive crest.
- D to H, this is wavelength because it is between two successive trough.
Thus, the distance that is not a wavelength in the image is C to E.
