cardiac muscle is striated. Uniquely, the cells of this kind of muscle are joined strongly together at adherens junctions that “enable the heart to contract forcefully without ripping the fibers apart.” 
 
        
             
        
        
        
 Planetary Nebula are the outer layers of a star that are lost when the star changes from a red giant to a white dwarf. A star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas.

Answer:
She is going at 30.4 m/s at the top of the 35-meter hill.    
Explanation:
We can find the velocity of the skier by energy conservation:

On the top of the hill 1 (h₁), she has only potential energy since she starts from rest. Now, on the top of the hill 2 (h₂), she has potential energy and kinetic energy.
 (1)
    (1)
Where:
m: is the mass of the skier
h₁: is the height 1 = 82 m
h₂: is the height 2 = 35 m
g: is the acceleration due to gravity = 9.81 m/s²  
v₂: is the speed of the skier at the top of h₂ =?
Now, by solving equation (1) for v₂ we have:
 
   
 
    
Therefore, she is going at 30.4 m/s at the top of the 35-meter hill.
I hope it helps you!
