What is gravitational potential |
| Answer» Value of gravitational potential at a point inside the gravitational field region of a source mass is the work done on a test mass to bring it from infinity to that point where it could experience the gravitational force of the source mass. Source mass is simply the body whose gravitational field we are considering here and test mass is any body which experiences it\'s gravitational force | |

State newton\'s law of cooling |
| Answer» | |
| 7328. |
What is newton\'s law of cooling |
| Answer» Newton’s law of cooling describes the rate at which an exposed body changes temperature through radiation which is approximately proportional to the difference between the object’s temperature and its surroundings, provided the difference is small, i.e.,The Newton’s law of cooling is given by,dT/dt = k(Tt – Ts)WhereTt = temperature at time t andTs = temperature of the surrounding, k = constant. The Newton’s Law of Cooling Formula is expressed byT(t) = Ts + (T0 – Ts) e-KtWhere,t = time,T(t) = temperature of the given body at time t,Ts = surrounding temperature,To = initial temperature of the body,k = constant. | |
