I already said it but its reactivity

The product in a chemical reaction is written on the Right side of the arrow, so
the product formed here in given reaction is :
Answer:
the angular speed is around 45
Explanation:
Answer:
8.5 m/s
Explanation:
please see paper for the work!
Answer:
The initial velocity is 50 m/s.
(C) is correct option.
Explanation:
Given that,
Time = 10 sec
For first half,
We need to calculate the height
Using equation of motion

....(I)
For second half,
We need to calculate the time
Using equation of motion



Put the value of h from equation (I)


According to question,


Put the value of t₁ and t₂



Here, g = 10
The initial velocity is


Hence, The initial velocity is 50 m/s.
