1.Convert the 1-D array to 3-D array
a = np.array([x for x in range(32)])
Answer:
print(o)
Output:
array([[[ 0, 1, 2, 3, 4, 5, 6, 7],
[ 8, 9, 10, 11, 12, 13, 14, 15]],
[[16, 17, 18, 19, 20, 21, 22, 23],
[24, 25, 26, 27, 28, 29, 30, 31]]])
2.Convert the value in the array to appropriate data type
a = np.array([[7.2, 5.4, 9.3],
[3.8, 6.7, 8.5]])
Answer:
print(o)
Output:
[[7 5 9]
[3 6 8]]
3.Extract value in between 7 to 15 from the given array
a = np.array([2, 6, 1, 9, 10, 3, 27])
Answer:
print(o)
Output:
[ 8 12 9 11]

Show, by the use of the truth table (truth matrix), that the (p ∨ q) ∨ [(¬p) ∧ (¬q)] is a contradiction.
The electric field at a distance of 2 m from an infinite line charge of charge density 4 nC/m is
Two masses mA = 2.8 kg and mB = 6.2 kg are on inclines and are connected together by a string as shown in the figure.
Ignore masses of the frictionless pulley and the cord.
The coefficient of kinetic friction between each mass and its incline is μk=0.34. If mA moves up, and mB moves down, determine their acceleration.

An industrial company claims that the mean pH level of the water in a nearby river is 6.8. You randomly select 19 water samples and measure their pH level. The mean and standard deviation are 6.5 and 0.25, respectively. Is there enough evidence to reject the company’s claim at a significance level of 0.05?
