<span>Given temperature ϑ = 56°C. Formula: speed of sound c = 331.3 + 0.606 × ϑ.Atϑ = 56°C the speed of sound c = 331.3 + 0.606 × 56 = 365.2 m/s.</span>
The answer is 17500 J for 35*10*50 and the answer is 16500 J for 55*10*30. Thus , the first object has more gravitational potential energy
Answer:
The delicate balance between temperature and magnetic domains is destabilized when a magnet is subjected to high temperatures. If a magnet is exposed to this temperature for an extended length of time or heated over its Curie temperature, it will lose its magnetism and become irreversibly demagnetized.
Explanation:
The equatorial radius of the earth is
r = 6378 km = 6378 x 10³ m
The earth makes 1 revolution in 24 hours.
The angular velocity is
ω = (2π rad)/(24*3600 s) = 7.2722 x 10⁻⁵ rad/s
The tangential velocity (linear velocity) at a point on the equator is
v = rω
= (6378 x 10³ m)*(7.2722 x 10⁻⁵ rad/s)
= 463.8 m/s
Answer: 463.8 m/s
