Answer:
Thus, the change in the weight of the person is 1.6N , option c is correct.
Explanation:
Higher frequencies are present in more dramatic events and have thus been the first to be noticed, but the frequencies of ordinary gravitational waves are relatively low and considerably more difficult to detect.
A gamma-ray burst (GRB), which was discovered by the orbiting Fermi gamma-ray burst monitor on 2017 August 17 at 12:41:06 UTC, triggered an automatic notice throughout the world in addition to a merger of black holes. Six minutes later, a gravitational-wave observatory in Hanford, Washington, detected a gravitational-wave candidate that occurred 2 seconds before the gamma-ray explosion.
This collection of data supports the merger of two neutron stars, as shown by a multi-messenger transient event that was detected by gravitational waves as well as electromagnetic (gamma-ray burst, optical, and infrared) spectrum observations.

Yes, you are pulling on the Earth, with equal force.
Your weight on Earth is equal to the Earth's weight on you.
I can't think of a way for you to go out and see it or measure it,
but there are two things we learn in Physics that tell us that it
must be true.
#1). Newton's 3rd Law of motion:
For every action, there is an equal, opposite reaction.
If the Earth pulls on me, then I must pull on the Earth with an
equal, opposite force.
#2). Newton's law of universal gravitation:
Gravitational force = (a Constant) · (mass₁) · (mass₂) / (distance)² .
Take a good, long, hard look at this formula for the gravitational force.
It tells the strength of the gravitational force between the Earth and you.
But it doesn't say WHICH object is (mass₁) and which object is (mass₂) !
It doesn't matter ! BOTH objects feel the same gravitational force !
Answer: Either it's B. The seismic waves frequency also changed multiple times.
or
D. As the wave passed through less dense material, the speed of the wave increased.
Explanation: I'll let you choose because I'm stumped on which one it is. They both sound like they would fit perfectly with the question and I've tried doing research on it but nothing can prove either one right or wrong for me.
I know seismic waves can change frequency given the density of rock\ground it's going through.
"The propagation velocity of seismic waves depends on density and elasticity of the medium as well as the type of wave. Velocity tends to increase with depth through Earth's crust and mantle, but drops sharply going from the mantle to outer core."
However, B. also fits nicely.
"Temperature tends to lower the speed of seismic waves and pressure tends to increase the speed. Pressure increases with depth in Earth because the weight of the rocks above gets larger with increasing depth."
Nevertheless, I hope it helps.
When it says something like 'on the verge of moving,' it means that the pulling force and static friction force and gravitational force all cancel out! Any more pulling force and it is ready to move!
At some point, you want F as a function of <span>μs</span>, to determine the force needed depending on the coefficient of static friction. This function, <span>F(<span>μs</span>)</span>, will rely on the angle θ as well, but we want to consider just one angle θ in every scenario. One value means it is constant.
But if we know the F, and we know <span>μs</span>, we can find what the constant angle θ must be!
If F is the pulling force, <span>FS</span> is the static friction force, and <span>FG</span> is gravitational force,
<span><span><span>Fnet</span>=0</span><span>=F+<span>FS</span>+<span>FG</span></span><span>=F+<span>FN</span><span>μs</span>+mgsinθ</span><span>=F+mgcosθ<span>μs</span>+mgsinθ</span><span>=0</span></span>
Then you can find <span>F(<span>μs</span>)</span>, but then there is the issue of solving for the θ<span> to make it true.</span>
