Answer:
a
Explanation:
The most reasonable conclusion of the above phenomenon is that water is a poor conductor of heat. Basically water is an insulator. The heat from surface to the bottom of the beaker will take a lot of time. Moreover, no convection current is formed so, heat might not even reach the bottom surface. Hydrogen bonding also play a vital role in determining the thermal properties of water.
hence option A is correct
F = ma
100 N= m . 5 ms⁻¹
100 / 5 = m
20 N ms = mass of object.
1. Protons and Neutrons
2.Inside nucleus
3. Covalent and chemical bonds?
I’m not sure about 3 but other 2 are right lol
