Answer:
Kr = 0.7618K
Explanation:
Suppose that the object's velocity is V, then his kinetic energy is:
K = 
K = 
K = 8
The rotational kinetic energy is
Kr = 
where I: The moment of inertia
ω: angular velocity
Kr =
Kr = 0.295
How the movement is without slipping, then
ω = 
ω = 
Thus
Kr = 
Kr = 6.095
8
----> 1
6.095
----->?
Kr = 0.7618K
Answer:
Electric flux 
Explanation:
Given that,
Electric field acting on the circular area, 
We need to find the electric flux through a circular area of radius 1.83 m that lies in the xy-plane. It lies in xy plane, such that the area vector point in z direction. The electric flux is given by :


Using dot product properties, we get the value of electric flux as :



So, the electric flux through a circular area is
. Hence, this is the required solution.
<h2> F = k×

</h2>
Explanation:
- The attractive or repulsive forces which act between any two charged species is an electric force.
- The electric force depends on the distance between the charged species and the amount of charge which can be calculated by the formula given as follows
F = k×
where, K is coulombs constant, which is equal to - 9 x10^9 
- The unit for K is newtons square meters per square coulombs.
- This is known as Coulomb's Law.
Answer: I-131, P-32, Sr-90, Co-60 & Technetium.
Explanation: Isotopes like I-131 are used to diagnose goiter in thyroid gland and isotopes like P-32 Sr-90 are used for treatment of skin cancer and Co-60 for cancer and technetium is used to monitor bone growth.
