We know that
v^2 = u^2 + 2aS
v= final velocity
u= initial velocity
a= acceleration due to gravity
S = displacement
S= (v^2 - u^2)÷2a
Work done= force * displacement
W = F * S
F= ma
W= ma * (v^2 - u^2)÷2a
W= 1/2 * m* (v^2-u^2)
If u=0 ( body starts from rest)
W= 1/2 * m * v^2=Kinetic energy

Let the force of smaller magnitude be A and the force of larger magnitude be B.
here,it is clearly given that the resultant force is R perpendicular to small force. hence, we can say that b is the hyopetenuse .
therefore, b² = R² + A²
=> R² = b² - A²
= 8²
= 64 .......................... ( 1 ).
here, it is also given that
A + B = 16
therefore , B = 16 - A ..........................( 2 ).
Now, by substituting ( 2 ) in ( 1 ).we get,
( 16 - A ) ²- A² = 64
=> 256 - 32A + A² - A² = 64
32A = 256 - 64 = 192
A = 192 / 32
= 6
hence, we get the result
B = 16 - A = 16 - 6 = 10
Therefore, the magnitude of the two vectors are 6 and 10.

Ernest Weil was a doctor. He had qualified as a doctor only the previous week. He was a good friend of Yuri. Albert told Yuri of his plan of staying away from the school. Yuri told him to go to Dr. Ernest Weil to get a medical certificate for that purpose. Dr. Weil really helped Einstein in this matter.

Electrons are found within the lobes. The plane (or planes) that the orbitals do not fill are called nodes. These are regions in which there is a 0 probability density of finding electrons.
The number of angular nodes = l = 1
The number of radial nodes = (n - l - 1) = 3 - 1 - 1 = 1
Total number of nodes = n - 1 = 3 - 1 = 2
