The area under the standard normal curve between z=0.19 and z=2.18 is,
P(0.19<z<2.18)= 0.4101
<h3>How can we calculate the area under the curve?</h3>To calculate the The area under the standard normal curve between z=0.19 and z=2.18, we are using two things,
<u>Step 1</u>: The formula,
P(0.19<z<2.18)= P(Z<2.18)- P(Z<0.19)
<u>Step 2</u>: The statistical values of the area under the curve we get from the picture.
Now we put the known values from the picture in the above formula, we get,
P(0.19<z<2.18)= P(Z<2.18)- P(Z<0.19)
Or, P(0.19<z<2.18)= 0.9854-0.5753
Or, P(0.19<z<2.18)= 0.4101
From the above calculation we can easily conclude that,
The area under the standard normal curve between z=0.19 and z=2.18 is,
P(0.19<z<2.18)= 0.4101

Explanation:
27 cm = 0.27 m
As the blocks are hanging on 2 sides of the pulley, their difference in mass would generate a net force toward the heavier side:
Let g = 9.81 m/s2
F = g(2.7 - 1.4) = 9.81*1.3 = 12.753 N
This force would generate a torque at 0.27 m moment arm
T = F*r = 12.753*0.27 = 3.44 Nm
The moment of inertia of the solid disk:
Where m = 0.78 kg is the disk mass and R = 0.27 m is the radius of the disk.
So the angular acceleration of the torque is
So the linear acceleration is its angular component times radius
