A diameter is a straight line that begins at one end of the circle and ends at the opposite end. The condition for a line to be a diameter is that it must pass through the centre of the circle. If a line that touches two points on the circle, does not pass from the centre of the circle, it cannot be called a diameter.
The length of the diameter is the measurement of the line that connects the two points of the circle.
Answer:280.216j/kg°C
Explanation:
Mass of metal=0.0663kg
mass of water=0.395kg
Final temperature=27.4°C
Temperature of metal=241°C
Temperature of water=25°C
specific heat capacity of water=4186j/kg°C
0.0663xax(241-27.4)=0.395x4186x(27.4-25)
0.0663xax213.6=0.395x4186x2.4
14.16168a=3968.328
a=3968.328 ➗ 14.16168
a=280.216j/kg°C

Energy released during an earthquake travels in the form of waves<span> around the Earth. Two types of seismic </span>wave<span> exist, </span>P<span>- and </span>S-waves<span>. They are different in the way that they travel through the Earth. ... They are transverse </span>waves<span> which mean the </span>vibrations<span> are at right angles to the direction of travel.</span>
The gravitational potential energy of an object depends on three things. Its mass, its height above the surface of the earth and the pull of gravity (which is assumed to always be 9.8 m/s².
The Formula for finding the GPE is : m x g x h where m = mass, g = gravitational acceleration and h is height from earth's surface.
Using this formula we can find that :
GPE= 75 x 9.8 x 300 = 220500J (where J is the SI unit for GPE and stands for Joules.
