A force can cause a resting object to move, or it can accelerate a moving object by changing the objects speed or direction
Answer:
Given:
Pressure,
Temperature, T = = 273 + (- 0.77) = 272.23 K
Diameter of oxygen molecule,
Speed of sound, v = 330 m/s
Solution:
Mean free path of oxygen is given by:
Now, substituting the given values in the above formula:
Now, the frequency, is given by:
Since, mean free path = wavelength =
Therefore,
The intrinsic brightness of a celestial object or <span>the rate of emission of radiation, visible or otherwise.</span>
So that the earth can exert a forward force on him too and push him forward.
This is an example of Newton's third law of motion.
Answer: Scientists believe that about 25 of the known elements are essential to life. Just four of these – carbon, oxygen, hydrogen, and nitrogen– make up about 96% of the human body. Six common elements that are important in living things are carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus. These large molecules make up the structures of cells and carry out many many processes essential to life.
