Answer:
Neutralization reaction
Explanation:
A neutralization reaction is an acid-base reaction that will yield a neutral solution because the end point of the reaction is reached in the process.
Neutralization reaction reactions occurs between an acid and a base where by the hydrogen and hydroxyl ions are combined to give water and the remaining ions produced the neutral salt.
When a strong acid and strong base combines, they produce a solution of pH 7 because they are ionized completely when the react.
Answer:
Once you've had chickenpox you can't again.
Explanation: the virus remains inactive in your nerve tissue. Although it's unlikely you will get chickenpox again, the virus may reactivate later in life and cause a related condition called shingles.
Answer:
Explanation:
Work is a force time the distance moved in the direction of that force, time is not a variable. Provided that the 50 N forces were applied in the same direction, the work done is identical. Assuming both applied force and direction of motion are horizontal W = Fd = 50(10) = 500J.
If the reason that one was slower is because the second person applied his force at an angle, let's say 60° below the horizontal, then the work done by the second person is 50cos60(10) = 250 J
Time IS a consideration for Power, the RATE of doing work. Provided the force and motion are horizontal, the first person applied twice as much Power as the second person doing an identical amount of work in half the time.
A. 4% you divide 2000 to 500 and you get 4 which is your answer
Lets write again formula for determening Ann's performance.
P = 70.443 + 4,885*t
where t is in hours. This is equation with P(t) which means that P only depends on variable t. If we express t=2.6 in formula we will find her expected performance.
P = 83.144
Now, since it says that she scored 16 points less than expected we need to find value of P-16
P - 16 = 67.144
After round we get that the answer is 67
