200g*1 mole/ 18g=11.1 moles There are 11.1 moles of water.
Answer:
Explanation:
Correct order of energy of energy states within an atom is as follows
1s , 2 s, 2 p 3 s ,3 p, 4s , 3d, 4p, 4p,5s etc.
There is discrepancies in this order due to overlapping of outer orbitals with inner orbitals so sometimes outer orbitals have lower energy.
When sediment has built up over time layers of rock start to form, starting with sedimentry rocks, then metamorphic rocks
"Using the ramp decreases the amount of force needed to move the boxes, but the boxes must be moved over a longer distance" is the way among the following choices given in the question that a ramp <span>to load boxes into a truck make work easier. The correct option among all the options that are given in the question is option "D".</span>
The time taken by the stone to hit the ground would be 5.12 seconds.
<h3>What are the three equations of motion?</h3>
There are three equations of motion given by Newton
The first equation is given as follows
v = u + at
the second equation is given as follows
S = ut + 1/2×a×t²
the third equation is given as follows
v² - u² = 2×a×s
Keep in mind that these calculations only apply to uniform acceleration.
As given in the problem, a stone is dropped from the helicopter which is ascending at the speed of 19.6 m/s
height(S) = 156.8 meters
initial velocity(u) = -19.6 m/s
acceleration(a) = 9.81 m/s²
By using the second equation of motion given by newton
S = ut + 1/2at²
S = 156.8m ,u= -19.6 m/s , a= 9.81 m/s² and t =? seconds
156.8= -19.6t + 9.81t²
t = 5.12 seconds
Thus, the time taken by the stone to hit the ground would be 5.12 seconds.
