Answer:
-775 rad/s^2
Explanation:
Knowing the initial and final angular speed is
and
, respectively. We can use the following formula for equation of motion to calculate the average angular acceleration in t = 0.569 seconds




Answer:

Explanation:
Using the
:-
If a solid mass of a known volume is submerged in a container of a fluid, the volume of the fluid displaced is equal to the volume of the solid mass.
Hence volume of mercury displaced is 
B acid + base → water + salt
Explanation:
The best equation that represents a neutralization reaction is:
acid + base → water + salt
In a neutralization reaction, an acid reacts with a base to produce salt and water only.
Here, hydrogen combines with hydroxide to form water.
Titration is usually used to carry out this reaction in the laboratory.
An indicator is added to the base and at end the color of the reaction changes.
At this point the acids have completely been neutralized with the base.
