Answer:
The answer is a," their receptors are sensitive to chemical molecules."
The acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².
The given parameters;
- <em>initial velocity of the engine, u = 1341 m/s</em>
- <em>final velocity of the engine, v = 7600 m/s</em>
- <em>time of motion, t = 2 minutes = 2 x 60 s = 120 s</em>
The acceleration of the SRB and main engine is calculated as follows;

Thus, the acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².

The electric field 4cm from the wire is

Given:
charge is distributed uniformly along a long straight wire.
electric field 2cm from the wire is 20n/c
To find:
electric field 4cm from the wire
what is electric field?
Electric field is the region around charge particle or charged body in which if another charge is placed it experiences electrostatic force.An electric field is the physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them.





thus the electric field 4cm from the wire is

Hello!
The <span>biochemical process that liberates energy content of food for living organs is called catabolism.
Catabolism is a process in which big molecules like those in the food we eat are broken down into small ones that can be used by the living organism to obtain energy. The energy that is liberated in this process is stored in molecules of adenosine triphosphate (ATP). These molecules are used by cells to produce energy in the process called cellular respiration, catalyzed by the enzyme ATPase.
Have a nice day!
