Answer:
the correct answer is C
Explanation:
When we express that the scale is 1:30 we mean that the objects of the realization are reduced by a factor of 30 in the graph, for example a distance of 30 cm in the graph is represented by a distance of 1 cm.
Therefore something that in the graph has n value to bring it to real size must be multiplied by the scale.
Applying this to our case if there is
10 boulder on the chart
in reality there are #_boulder = 10 30
#_boulder = 300 boulder
so the correct answer is C
To solve this problem we will begin by finding the pressure through density and average depth. Later we will find the Force, by means of the relation of the pressure and the area.
Here,
h = Depth average
= Density
Moreover,
Replacing,
Finally the force
By the use of "Solar cells" or "Solar panel", we can trap solar energy in silicon/germanium rods, then we can convert in into electricity too.
Hope this helps!
Answer:
debris basin is you answering.
Answer:
(a)
x=7.83 Kgm/s
y=5.48 Kgm/s
(b)
191.25 N
Explanation:
(a)
Change in momentum in x direction
where m is mass and v is the velocity and 
is the angle of kick
Substituting m=0.425 Kg, v=22.5m/s and 
Change in momentum in y direction
(b)
Force exerted by the player
F=mv/t where t is time
Substituting 
F=(0.425*22.5)/0.05= 191.25 N
