Given:
max displacement, A = 3.2 m
f= 50 Hz
at t = 0, displacement, d = 150 cm = 1.5 m
Solution:
Displacement in the general form is represented by:
d = Asin(ωt ± α)
d = 3.2sin(2πft ± α)
d = 3.2sin(100πt ± α)
where,
A = 3.2 m,
ω = 2πf = 100π
Now,
at t = 0,
1.5 = 3.2sin(100π(0) ± α )
1.5 = 3.2sinα
sin α = 
= 0.4687
α = 
= 27.95° = 0.488 radian
Now, we can express displacement in the form of 'Asin(wt + α)' as:
d = 3.2sin(100πt ± 0.488 )
The primary source of voltage for a storage battery is; Active Source
<h3>What is Voltage?</h3>
Voltage is defined as the pressure from an electrical circuit's power source that pushes charged current electrons through a conducting loop, that enables them to do work such as illuminating a light.
Now, there are two primary sources of voltage which are namely active sources and passive sources.
The Active sources delivers power or energy to the circuit while the Passive sources utilizes power or energy from the circuit.
Thus, the storage battery will be an active source

Option D is correct. The component of college life known as general education deals with the knowledge, abilities, attitudes, and values that define educated people.
It respects the linkages between different bodies of knowledge and is not constrained by disciplines. Graduates with a NOVA degree will have the ability to write effectively and engage in civic participation, critical thinking, professional preparation, numeric literacy, and scientific literacy. As a result, the College has chosen the following list of general education electives in accordance with the general education standards of the Virginia Community College System. In order to choose the best course for their curriculum and/or transferability to another college, it is strongly advised that students speak with their academic advisor or counselor.
