Cardiac, smooth, and skeletal. cardiac muscle cells are located in the walls of the heart and appear striated and are under involuntary control. smooth muscle fibers are located in walls of hollow visceral organs except the heart they also appear striated. skeleton muscle is found between bones and uses tendons to connect to the epimysium to the periosteum, or the outer covering of bone. skeletal muscle is shaped and adapted in many ways.

Answer: 1.43
Explanation:
Given that:
C (critical angle) = 44.4°
n (refractive index of plastic) = ?
Apply the formula n = 1/sineC, the index of refraction for the plastic can be obtained by:
n = 1/sineC
n = 1/sine 44.4°
n = (1/0.6996)
n = 1.43
Thus, the index of refraction for the plastic is 1.43
Answer: The current required will be of 1.25 Ampere.
Explanation:
Voltage of one battery= 1.5 Volts
Voltage required by DVD player to operate, V = 6 × 1.5 = 9 Volts
Resistance offered by the device, R = 7.2 Ohms
V = IR (Ohm's law)
The current required will be of 1.25 Ampere.
