10^-4 = 0.0001 * 3.11 = 0.000311
Answer:
One way to test the hypothesis is to create two waves, one in the air and one on the ground at the same time. One of them for the elephant to get closer and another for the elephants to move away. Observe the reaction of the animal and with this we know which sound came first.
Explanation:
This hypothesis is based on the fact that the speed of sound in air is v = 343 m / s with a small variation with temperature.
The speed of sound in solid soil is an average of the speed of its constituent media, giving values between
wood 3900 m / s
concrete 4000 m / s
fabrics 1540 m / s
earth 5000 m / s wave S
ground 7000 m / s P wave
we can see that the speed on solid earth is an order of magnitude greater than in air.
One way to test the hypothesis is to create two waves, one in the air and one on the ground at the same time. One of them for the elephant to get closer and another for the elephants to move away. Observe the reaction of the animal and with this we know which sound came first.
From the initial information, the wave going through the ground should arrive first.
Explanation:
(a) The Schrodinger's wave function represent the position of a particle at a particular instant of time. It is also known as the probability amplitude. It is also used to find the location of a particle.
(b) The width of a potential well,
For first energy level, n = 1
Energy in infinite potential well is given by :
E = 0.0120 Joules
For second energy level, n = 2
E = 0.0483 Joules
For third energy level, n = 3
E = 0.108 Joules
Hence, this is the required solution.
Answer:
The answer is "Choice B and Choice C".
Explanation:
In this question, the two features, which make electromagnetic waves effective for interaction, which they don't really need a method of travel of data and move information quite fast. The motion among magnetic and electrical forces is generated by electromagnetic radiation. These waves will spread without the need for a source for their movement, and they have high speed and also the electromagnetic waves it has the same frequency as light.
