Acid it is i believe........
Question 1: Newtonian. It refers to work of Newton. Light, electrical and chemical energies are different forms of energy.
Question 2: Nuclear power plants. Heat , Sunlight and energy in atoms are not nuclear energies.
Question 3: Batteries. the other two are examples of mechanical energy. But batteries are examples for chemical energy.
In a surface wave (like water) the water goes up and down, but the wave travels across (parallel to) the surface.
2 Newtons to the right.
3 newtons are needed to over come the friction. There are 2 left over.
So the answer is 2 newtons to the right.
5 - 3 = 2
Answer:
Option C) 2,090 J/(mol K)
Explanation:
Data:
Volume in the beaker = 429 ml
temperature = 20° C
Density = 789 kg/m³
Equilibrium reading = 429
volume change = 29 ml
= 0.029 L
Energy change = mcΔT
U + PΔV
