Answer:
1/3
Explanation:
We can solve the problem by using the lens equation:
where
f is the focal length
p is the distance of the object from the lens
q is the distance of the image from the lens
Here we have a divering lens, so the focal length must be taken as negative (-f). Moreover, we know that the object is placed at a distance of twice the focal length, so
So we can find q from the equation:
Now we can find the magnification of the image, given by:
We have that the Force is mathematically given as
F=170.833N
<h3></h3><h3>Force </h3>Question Parameters:
Generally the equation for the Force is mathematically given as
Therefore
F=41/0.24
F=170.833N

Explanation:
Let be the airspeed.
Let be the cross wind speed.
We know that,ground speed is the vector sum of airspeed and cross wind speed and airspeed is perpendicular to cross wind speed.
If and
are two perpendicular vectors,the resultant vector has the magnitude
Given,
So,the ground speed is
