go here this is a really good video to help with balacing chemical equations
D. It’s a composite because it’s a mixture of cement, sand, and other granular pieces.
A loess is...
<em>A clastic, silt-sized sediment that is formed by the accumulation of wind-blown dust. 10% of the earth's area is covered by loess or similar deposits. </em>

Answer:
c will have the largest charge
Explanation:
because more lines are coming more line means more foce is required
Answer:
D) - 0.72 secs
Explanation:
Parameters given:
Height of bridge = 40ft = 12.19 m
Initial velocity of Bill's stone = 0m/s
Initial velocity of Ted's stone = 10m/s
We find the time it take Bill's stone to bit the river and the time it takes Ted's stone to hit the river. Then we find the time difference.
Using one of the equations of motion:
For Bill:
S = ut + ½gt²
Where g = 9.8 m/s
12.19 = 0 + ½*9.8*t²
t² = 12.19/4.9 = 2.49
t = 1.58 secs
For Ted:
S = uT + ½gT²
12.19 = 10*T + ½*9.8*T²
=> 4.9T² + 10T - 12.19 = 0
Using quadratic formula and retaining only the positive value, we get that:
T = 0.86 secs
Time difference between Bill's throw and Ted's throw is:
0.86 - 1.58 = - 0.72 secs
In reality, this means that Ted must throw his stone 0.72 secs before Bill throws his for both stones to land the same time.
