Answer Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.

Answer:
Explanation:
given wave = 8.5 x 10⁻³ cos ( 172 x - 2730t )
here wave no k = 172
angular frequency ω = 2730
velocity of wave on the string
a )
v = ω / k
= 2730 / 172
= 15.87 m/s
time taken to travel full length
= 1.2 / 15.87
= 75.6 x 10⁻³ s
b )
For velocity of wave on the wire the formula is
T is tension and m is mass per unit length of wire
m = .0121 / ( 9.8 x 1.2 )
= 1.03 x 10⁻³ kg / m
15.87 =
W = .259 N
c ) wavelength λ = 2π / k
= 2 x 3.14 / 172
= .0182 m
no of wave length
n = 1.2 / .0182
= 66 approx .
No it doesn’t occur anywhere
There are areas that are prone to these earthquakes and volcanoes
<h3><u>Answer;</u></h3>
Centripetal acceleration = 0.931 m/s²
Centripetal force = = 1.234 × 10^-4 Newtons
<h3><u>Explanation;</u></h3>
Centripetal acceleration is given by the formula v²/r, where r is the radius of the circular path and v is the velocity of a body;
Centripetal acc = 3.2²/11
= 0.931 m/s²
Centripetal force is a force that acts on an object or a body in circular path and is directed towards the center of the circular path.
Centripetal force is given by the formula;
mv²/r ; where m is the mass of the body, r is the radius of the circular path and v is the velocity of a body;
mass = 33 mg or 1.33 × 10^-6 kg, velocity = 3.20 m/s and r = 11 m
Therefore;
Centripetal force = (1.33 ×10^-6 × 3.1²)/ 11
= 1.234 × 10^-4 Newtons
