Answer: temperature and
Explanation: temperature and
and humidity the most essential factor affecting the speed of sound in gas.. in gas, sound speed changes with change in temperature. For stable temperature, the speed of sound is independent of pressure. For every increase in temperature, there is a corresponding increase in thermal energy as molecules do resonate faster. Humidity has little effect on the speed of sound. The speed of sound also depends on d relationship between molecules in gas
Answer:
The correct answer would be - oxygen will passively diffuse into the cells.
Explanation:
As the oxygen molecules are very small and has no polarity or no charge they show the passive diffusion through the plasma membrane from the higher concentration to lower concentration inside the cell.
In the lungs the oxygen diffuses out the air sacs into the blood as the air sacs of lungs have higher concentration of oxygen than the blood stream and as the various cells perform the aerobic cellular respiration the concentration of the oxygen inside of the cell become low to the blood so oxygen diffuses into cells.
Thus, the correct answer is - oxygen will passively diffuse into the cells.
Answer:
All energy in the system are either potential or kinetic.
Option A to D are true
Explanation:
Kinetic Energy is the energy in a body when the body is not at rest (i.e. when it is in motion)
Whole
The potential energy of an object is energy of the body in a stored form. This means that when the body is at rest (not moving but waiting to do work). This is seen in Option A where the ball is held motionless above the floor.
The potential energy of a body decreases when the body moves downward and the kinetic energy increases. This is seen in Option B and C.
The last option D is supported by the first law of thermodynamics, also known as Law of Conservation of Energy, which states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. The potential e ergy of the body when held motionless above the floor is equal to the kinetic energy of the body when it hits the floor.
