Explanation:
Answer:
its surface temperature = 54.84 ° C
Explanation:
The density of aluminium = 2700 kg/m ³
Heat capacity = 897 J/Kg.K
radius of the sphere (r) = 0.081029 m
= 25 °C
= 124.978 °C
time (t) = 767.276 s
Using the formula :
where.
Replacing our values ;we have:
T ≅ 54.84 ° C
Therefore, its surface temperature = 54.84 ° C
At the start, the ball is at rest and therefore, u=0 m/s. As it leaves the bat, v= 50 m/s
From equations of motion, v=u+at = at (since u=o)
a=v/t = 50/0.04 = 121250 m/s^2
From Newton's second law,
F=ma = 145/1000 *1250 = 181.25 N
The decarboxylation reaction involves the removal and replacement of a carboxyl group with hydrogen.
<h3>What is a decarboxylation reaction?</h3>
A decarboxylation reaction is one in which the carboxyl group in a carboxylic acid is replaced with hydrogen.
In living organisms, decarboxylation reactions are catalyzed by enzymes called decarboxylases or carboxy-lyases.
The decarboxylation of beta-carbonyl esters proceeds through a cyclic transition state giving an enol intermediate which then tautomerises to the carbonyl.
Therefore, a decarboxylation reaction involves the removal and replacement of a carboxyl group with hydrogen.

Answer:
The average impact force is 12000 newtons.
Explanation:
By Impact Theorem we know that impact done by the sledge hammer on the chisel is equal to the change in the linear momentum of the former. The mathematical model that represents the situation is now described:
(1)
Where:
- Average impact force, in newtons.
- Duration of the impact, in seconds.
- Mass of the sledge hammer, in kilograms.
, - Initial and final velocity, in meters per second.
If we know that , , and , then we estimate the average impact force is:
The average impact force is 12000 newtons.
