I'm pretty sure that's the answer
The correct answer is C. HIPAA
This is the acronym for <span>Health Insurance Portability and Accountability Act. This was done to prevent illegal disclosing of data which was stored in computers and was passed in 1996 when it was signed by the then incumbent president Bill Clinton.</span>
Answer: 
It is given that:
Density of material =ρ
radius of inner spherical shell = 
radius of outer spherical shell=
we know that the volume of sphere is 
Volume of the given spherical shell = 
Then mass of the spherical shell can be calculate as:
Mass, m=density/ volume
Answer:
7 s
Explanation:
u = Initial velocity of rock = 12.2 m/s
= Angle of throw = 
x = Displacement in x direction = 25 m
Displacement in x direction is given by
Time taken to reach the ground is 7 s.
Answer:
0.001152m
Explanation:
Linear expansivity of a material is the change in length of the material per unit length per degree rise in temperature. Mathematically,
¢ = ∆L/L1∆°C
¢ is the linear expansivity of the material = 12 x 10⁻⁶ °C⁻¹
Where ∆L is the change in length = L2-L1
L2 is the final length = ?
L1 is the initial length = 12m
∆°C is the change in temperature = °C2 - °C1 = 50-(-30) = 80°C
Substituting this values inside the formula to get the final length L2 after expansion, we have;
12 x 10⁻⁶ °C⁻¹ = L2-12/12×80
12 x 10⁻⁶ °C⁻¹ = L2-12/960
L2-12= 960×12 x 10⁻⁶ °C⁻¹
L2-12 = 0.001152
L2 = 12+0.001152
L2 = 12.001152m
Expansion will be the change in length L2-L1 = 12.001152-12
= 0.001152m
The expansion cracks between the slabs should be 0.001152m wide to prevent buckling
