Answer:
3432 Hz.
Explanation:
The resonant frequency of the canal can be calculated as follows:
f = v/ 4l
Here, f is frequency, v is velocity of sound and l is the pipe length.
l = 2.5 cm = 0.025m and v = 343.2m/s.
Put these values to find the resonant frequency
f = 343.2 / 4 * 0.025.
f = 3432 Hz.
Thus, the answer is 3432 Hz.
Answer:
(A). heparinized saline.
Explanation:
Femoral popliteal surgery can be defined as medical procedure, which is used for the treatment of femoral artery disease. The chemical hemostatic agent that is used during femoral popliteal surgery is heparinized saline.
Heparin is an anticoagulant, which blocks blood clotting. Like other surgeries, popliteal bypass surgery also increases chances of formation of blood clots. Hence, heparinized saline is used for prevention of occlusion or clotting during femoral bypass.
Thus, the correct answer is option (A).
The heart rate of the fetus in relation to the contractions is the priority consideration while caring for a mother who is having strong contractions one minute apart.
There are a number of point which have to be taken care of when a mother is having strong contractions which are 1 minute apart but the priority is always to check the status of the fetus. This is important because the blood flow of the placenta gets interrupted temporarily with every contraction and therefore if the contractions are too strong and too long lasting, the fetus might not able to tolerate them.

Answer:
The correct answer will be myosin.
Explanation:
Myofibril in the muscle consists of thick filaments and thin filaments. The protein present in the thick filament is known as "myosin", a protein which converts the chemical energy of ATP into mechanical energy. It moves on the thin actin filaments and is known as motor protein and helps in the generation of force and movement.
This myosin protein is composed of the heavy chain and many light chains which is divided into globular head, neck and tail region.
Thus, myosin is the correct answer.
