See lessAn object of mass 13 kg is moving with a uniform velocity of 5 ms-1. What is the kinetic energy possessed by the object ?
Mass of object = 13 Kg Speed of object = 5 m/s Now from the above explanation, we can see that, ? Kinetic energy possessed by the object = 1/2 × 13 × (5) ? 1/2 × 13 × 25 = 162.5 J.

See lessIf the electronic configuration of an element is 2, 8, 2, to which period of the Modern Periodic Table does it belong ?
Element with electronic configuration 2,8,2 belongs to 3rd period and 2nd group. The valence electrons give us the idea of group number. As the electrons are divided into 3 different shell therefore period number is 3.

What is the first law of thermodynamics?
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.

See lessWho demonstrated that objects of different masses would reach the ground together when dropped from the same height ?
According to Galileo Galilei, if objects of different masses are dropped from the same height in the absence of air resistance the bodies will ground together at the same time.
