Seismic waves do not travel along the Earth’s surface. The statement is false.
<h3>
what are seismic waves?</h3>
The seismic waves can be defined as the waves full of energy that travel through the Earth's layer, these waves are the result of earthquake.
They can further be divided into two types body wave and surface waves. The body waves travel in the interior of the Earth and the surface waves travel at the surface of the Earth.
The seismic waves can have an amplitude of few centimeters in large earthquake. They travel slower as compared to the body waves.
Hence Seismic waves do not travel along the Earth’s surface. The statement is false.

Answer:
a. 0.8 cm
Explanation:
The distance of the object from the lens, u = 1 cm
The magnification of the lens, m = 5
The focus of a lens formula is given as follows;
The magnification of the lens, m = -v/u
Where;
v = The distance of the image from the lens
Therefore, we have;
v = m × u
∴ v = 5 × 1 cm = 5 cm (on the other side of the lens)
From which we get;
The focal length ≈ 0.8 cm
Answer:
0.000230144 N
Explanation:
n = Number of electrons = 
q = Charge of electron = 
k = Coulomb constant = 
r = Distance between obects = 1 m
The force would be
The force would be 0.000230144 N
<span>The answer is Music Mnemonics.
Mnemonic is originally coming from the Ancient Greek word means “memory”. It is the study and development of systems for improving and assisting the memory. Mnemonic techniques are more specific memory aids. Music Mnemonic is a way we used to remember song lyrics and rhythmic movement.</span>
