Initially its moving with tail wind so here the speed of wind will support the motion of the plane
so we can say
now when its moving with head wind we can say that wind is opposite to the motion of the plane
now by using above two equations we can find speed of palne as well as speed of wind
The force on the fry is
Explanation:
We can find the force acting on the fry by using Newton's second law:
where
F is the net force on the fry
m is its mass
a is its acceleration
For the fry in this problem,
Therefore, the force exerted on the fry is

Answer:
a.
b.
Explanation:
#Apply surface charge density, electric field, and Gauss law to solve:
a. Surface charge density is defined as charge per area denoted as
, and the strength of the electric field outside the sphere
Using Gauss Law, total electric flux out of a closed surface is equal to the total charge enclosed divided by the permittivity.
#surface charge outside sphere.
Hence, the new charge density on the outside of the sphere is
b. The strength of the electric field just outside the sphere is calculated as:
From a above, we know the new surface charge to be ,
Hence, the strength of the electric field just outside the sphere is
