Answer:
Amplitude, A = 5 m
Explanation:
Let a progressive wave is given by equation :
.....(1)
The general equation of a progressive wave is given by :
....(2)
Here,
A is the amplitude of the wave
is the angular frequency
k is propagation constant
We need to find the amplitude of the wave.
If we compare equations (1) and (2), we find that the amplitude of the given plane progressive wave is 5 m.
Answer:
Explanation:
Given
mass of stone=0.250 kg
Let initial velocity with which it is thrown upward is u
therefore after time t it's velocity is zero at highest point
t=
where g= gravity at earth
therefore -------1
Now same thing is done in Planet X where gravity is g'
therefore time taken by stone to reach surface is
-------2
Divide 1 & 2
=
=
g'=
Answer:
d
When hydrogen atoms merge to form helium atoms, the helium atoms have slightly more mass than the hydrogen atoms that combined to make them.
<em>The first blank is </em><em>robust watermark</em>; a robust watermark will not resist tampering.

<h3>What is a watermark?</h3>
A watermark is a faint design made in paper during manufacture that is visible when held against the light and clearly identifies the maker.
The watermark can be of different types depending on the application and they include:
- A robust watermark will not resist tampering.
- A fragile watermark will resist manipulations of the media.
Thus, The first blank is robust watermark; a robust watermark will not resist tampering.
The second blank is fragile watermark; a fragile watermark will resist manipulations of the media.
