you're welcome
but next time try to study harder.
Answer: A=1, B=3, C=12
Explanation:
For this problem, you will need to know your unit conversions. There are 3 ft in 1 yard. Knowing this, we can find A, B, C.
For A and B, we know that we want to cancel out ft so the answer can be in yards. To do so, we need to put B=3 and A=1.
Now that we know the unit conversion, we can directly solve.
36 ft×(1 yd/3 ft)=12 yd
Our final answer is A=1, B=3, C=12.
Answer: The theoretical yield is 6 rings.
Explanation:
Theoretical yield is predicted or estimated value.
Jeweler used 2 sapphires for 1 ring
Then for each sapphire there will be =
rings are used
For 12 sapphire =
will be used
Out of 10 rings 6 rings with 2 sapphires will be made.
The theoretical yield is 6 rings.
Answer:
Charged objects have an imbalance of charge - either more negative electrons than positive protons or vice versa. And neutral objects have a balance of charge - equal numbers of protons and electrons. ... Their presence (or absence) will have no direct bearing upon whether an object is charged or uncharged.
