The energy flow in the ecosystem is important to maintain an ecological balance. The producers synthesis food by the process of photosynthesis. A part of the energy is stored within the plants. The remaining energy is utilized by the plants in their growth and development.
Answer:
F = Gm1m2/r^2 where G = 6.67x10^-11, m1 =1300, m2 = 7800, r = 0.23m
F = 6.67x10^-11 *1300*7800/(0.23)^2 = 0.0127852N
Explanation:
Answer:
No we cannot perform any experiment that tells us weather we are moving or not at a constant speed.
Explanation:
Motion of any body is relative to other reference bodies. We can perceive motion only if our position with respect to a fixed object changes. This is the fundamental concept of reference frame in classical physics or Newtonian Physics that motion is always from a reference.
We choose a fixed body as reference and ,measure the distance we cover from this fixed point and also our speed with respect to this fixed point. The choice of frame of reference is completely dependent on the observer.
Since in the given case a reference cannot be established outside the plane thus we cannot detect our motion.
The approximate speed of sound is about 761 mph or 335.28 meters/second.
<h3>What's the approximate speed of sound?</h3>
If we consider the normal atmosphere at sea level, the speed of sound is about 761 mph or 335.28 meters/second. The speed of sound is different in different mediums such as solid and liquid.
So we can conclude that the approximate speed of sound is about 761 mph or 335.28 meters/second.
