Answer:
Y = 4.775 x 10⁹ Pa = 4.775 GPa
Explanation:
First, we calculate the stress on the rod:

Now, we calculate the strain:

Now, we will calculate the Young's Modulus (Y):

<u>Y = 4.775 x 10⁹ Pa = 4.775 GPa</u>
Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH), which can be used throughout the cell to power metabolism and construct new cellular components.
#1
length of one complete wave shape is known as wavelength
#2
Frequency is defined as number of oscillations per second or number of waves passing through a point in one second.
#3
One Time period is the time to cover one complete wavelength distance by the wave
#4
relation between time period and frequency is given as

#5
Time period of simple pendulum is given as

so it depends on length of pendulum and acceleration due to gravity
#6
amplitude of the wave is the height above the axis to which particle can attain its maximum position or its maximum height on y axis is amplitude
Length of the pendulum (l) = 2 m
Acceleration due to gravity = g = 9.8 m/s^2
For small amplitude, the pendulum will undergo simple harmonic motion.
Hence, the time period of the pendulum for small amplitude = 
Now, plug the values of l and g
T = 
T = 2 × 3.14 × 0.451
T = 2.83 seconds
Hence, the time period of the pendulum for small amplitude = 2.83 s
