Final velocity is equal to initial velocity plus at (where a is acceleration and t is time), so Vf = Vi + at
Using that formula;
Vf = 0 + 12.27(3.19)
Vf = 39.14 m/s
Note: you started from rest, so your initial velocity is 0.
Answer:
632.5 MPa
Explanation:
= Matrix stress at fiber failure = 10 MPa
= Volume fraction of fiber = 0.25
= Fiber fracture strength = 2.5 GPa
The longitudinal strength of a composite is given by
The longitudinal strength of the aligned carbon fiber-epoxy matrix composite is 632.5 MPa
Answer:
7.5 N/m
Explanation:
Potential energy of a spring can be calculated using below formula
Potential energy= 1/2kx^2
potential energy = 60 J
X= displacement = 4 m
K= spring constant=?
Substitute the values we have
60= 1/2 × K × 4^2
60= 1/2 × K × 16
60= K × 8
K= 7.5 N/m
Hence, the spring constant of the spring is 7.5 N/m
Answer:
Ovaries, the female reproductive organs, have two main functions: to produce female germ cells (called eggs or oocytes) and hormones (estrogen and progesterone), which regulate the function of the ovaries.
For the 1st imagine you can use numbers such as to count the eyes or the legs. The second image you could count how many circles are in the image. The third one you could use numbers to count the wheels.
