Answer:
19500kg
Explanation:
If you divide 195000N by 10
the difference of 10 dB is considered as having 10 times the intensity, so difference of 40 dB means :
=》10 × 10 × 10 × 10
=》10000 times
so the the intensity of one sound is 10000 times the other one.
Gravitational Potential Energy (GPE) before fall = Kinetic energy on impact
GPE = mgh
GPE = 5kg x 9.8m/s^2 x 10m
GPE = 490 J
Kinetic Energy = 490 J
(This is assuming that gravitation field strength (g) is 9.8m/s^2, sometimes you may round this to 10m/s^2, therefore making the final result:
Kinetic energy = 500 J)
The refractive index is the ratio of the speed in a vacuum to the speed of light in the given medium. If the refractive index is too low, there will not be a large bending, or deviation, of the light beam from its original path.
The small deviation will make it difficult to carry out the experiment, and is more likely to cause errors. Therefore, larger refractive indexes should be used, in order to ensure that the bending of the light beams is easily traceable.
The cylinder takes in the gas/air mixture during the intake stroke.
The cylinder compresses the gas/air mixture during the compression stroke.
The gas/air mixture burns and generates power during the power stroke.
The cylinder forces the gas/air mixture out during the exhaust stroke.
