If a molecule is found to have four hybrid sp3 then we say that it has a <span>tetrahedral molecular geometry. thsi is the correct term to define this type of molecules. So your option would be C. Hope this is useful</span>
<span>D. in back of the lens, because the rays are unaffected until it goes through the lens. In that moment the direction of the rays is modified, making them get closer to each other and all of them converge in a point behind the lens.</span>
Answer:
Replication
Explanation:
<em>The process of running multiple trials for each measurement during an experiment and finding the average is referred to as </em><em>replication.</em>
Replication is one of the attributes of good measurements/experiments because it reduces variability and increases the accuracy of the outcome. It also ensures that relevant statistical analysis can be carried out on the data collected via replicative measurements.
Answer:
Acceleration=24.9ft^2/s^2
Angular acceleration=1.47rads/s
Explanation:
Note before the ladder is inclined at 30° to the horizontal with a length of 16ft
Hence angular velocity = 6/8=0.75rad/s
acceleration Ab=Aa +(Ab/a)+(Ab/a)t
4+0.75^2*16+a*16
0=0.75^2*16cos30°-a*16sin30°---1
Ab=0+0.75^2sin30°+a*16cos30°----2
Solving equation 1
(0.75^2*16cos30/16sin30)=angular acceleration=a=1.47rad/s
Also from equation 2
Ab=0.75^2*16sin30+1.47*16cos30=24.9ft^2/s^2
