Answer:
a periscope use total internal reflection to allow us to see things
the reflection happens at 45°
Explanation:
S-waves<span> passing from the </span>mantle<span> to the core are absorbed because shear </span>waves<span>cannot be </span>transmitted through<span> liquids.
Hope this helps!</span>
Answer:
The water usually rushes back too enthusiastically, causing a splash – and the bigger the rock, the bigger the splash. The splash then creates even more ripples that tend to move away from where the rock went into the water.
Work = force × distance × cos(angle)
work = (25)(50)(cos (40))
work = 957.56 Joules
= 9.6x10^2 Joules
To develop this problem it is necessary to use the equations of description of the simple harmonic movement in which the acceleration and angular velocity are expressed as a function of the Amplitude.
Our values are given as


The angular velocity of a body can be described as a function of frequency as



PART A) The expression for the maximum angular velocity is given by the amplitude so that



PART B) The maximum acceleration on your part would be given by the expression
