1. a fiber-reinforced composite material has moduli of elasticity in the longitudinal and transverse directions of 6.9 gpa and 3.5 gpa, respectively. if fibers make up 25% of the composite volume and 56% of them are oriented in the longitudinal direction, find the moduli of elasticity of the fiber and matrix phases. assume that all fibers not oriented in the longitudinal direction are oriented transversely.
answer: 4 joules
given: charge = 1c
potential difference = 4v
now, we can find the work done is moving a charge across a potential difference. the formula used is:
work done (w) = charge (q) × potential difference (v)
⇒ work done = 1c×4v
= 4 joules
velocity is a vector which shows direction and rate of motion speed and velocity are not the same
the answer is
c. tilt of the axis
this question is more related to biology.
but i believe the answer is adipose tissue. the functions of adipose are precisely to store energy for later use and cushion and insulate the body.
