Answer:
Moment of Inertia, I = 0.016 kgm²
Explanation:
Mass of the ball, m = 0.20 kg
Length of the pitcher's arm, l = 0.28
Radius of the circular arc, r = 0.28 m
Moment of Inertia is given by the formula:
I = mr²
I = 0.20 * 0.28²
I = 0.20 * 0.0784
I = 0.01568
I = 0.016 kgm²
The purpose of nucleophilic substitution reactions of alkyl halides experiment is to demonstrate in the laboratory setting Nucleophilic substitution reactions of alkyl halides.
In this it is been aimed to observe nucleophilic substitution reactions, SN1 and SN2 will by the addition of a solvent to mixtures of alkyl halides. In order to make this experiment effective a standard procedure is being used and noted observations while each reaction occurred.
Nucleophilic substitution reactions are an important class of reactions that allow the interconversion of functional groups. For alcohols, the range of substitution reactions possible can be increased by utilizing the tosylates (R-OTs), an alternative method of converting the -OH to a better leaving group.

Answer:
Time taken, t = 4.86 seconds
Explanation:
Given that,
Acceleration of a particular automobile, 
Initial speed of the automobile, u = 75 km/h = 20.83 m/s
Final speed of the automobile, v = 110 km/h = 30.55 m/s
We need to find the time taken to accelerate from u to v. Let t is the time taken. It can be calculate as :
t = 4.86 seconds
So, the time taken by the automobile is 4.86 seconds. Hence, this is the required solution.
Answer
given,
Mass of satellite, m = 4500 kg
Mass of the earth, M = 6 x 10²⁴ Kg
Earth circular orbit radius, R = 9.3 x 10⁶ m
a) To find the speed of the satellite
we need to equate the gravitation force between earth and satellite with the centripetal force.
V = 6559.89 m/s
b) Minimum amount of energy of satellite
E = 9.68 x 10¹⁰ J
Minimum amount of energy require to move satellite is equal to E = 9.68 x 10¹⁰ J
