Viscosity<span> and surface tension is not the same</span>
Answer:b
Explanation:
When a covalent bond is nonpolar, it implies that there is a symmetric distribution of the electron cloud between the the two nuclei. That is, the electron cloud of the shared pair is positioned equidistant from the two bonding atoms. In this case, the both atoms attract electrons equally and the molecule lacks a permanent dipole.
The peremeter will be 20√13
The list of options to answer this question is:
A.kinectic energy is transformed into thermal energy.
B.electrical energy is transformed into potential energy.
C.potential energy is transformed into kinectic energy.
D.mechanical energy is transformed into chemical energy.
The answer is the option A. A.kinectic energy is transformed into thermal energy.
As you know energy cannot be lost but transformed.
When friction force acts over the tyres it increases the speed of the particles in the tyres which is thermal energy, this thermal energy increase comes from kinetic energy loss.
Answer:
Whenever a force is applied to an object, causing the object to move, work is done by the force. ... Work can be either positive or negative: if the force has a component in the same direction as the displacement of the object, the force is doing positive work
