Of course steady state condition occurs in almost any system but time it will occurs varies among system. for this kind of system, conduction, steady state conduction occurs when the temperature change from one point to the point is already constant. steady state is not achieved immediately because the heat travels and material will not be heated at the same way at the starting point.
Light gates are more reliable. When using a manual stop watch, it is difficult to stop it at an exact time. A light gate is able to detect when an object passes through a 'gate' with the infrared transmitter and receiver.
Explanation:
A light bulb changes electrical energy into <em>heat energy and light energy .</em>
Answer:
A feature and a coin dropped from the same height falls at the same speed at the condition at free fall,both coin and feature gain same acceleration of 9.8m/s^2.
Isotope has 57.40% abundance
the other one 100% - 57.40% = 42.60%
mass of 121 (% abundance) + mass of 123 (% abundance) = total mass (atomic weight)
(120.9038 amu)(0.5740) + (x amu)(0.426) = 121.76 amu
x = 122.9136
hope this help
