The rate of a reaction increases if:<span>
The temperature is increased.
The concentration of a dissolved reactant is increased.
The pressure of a reacting gas is increased.
Solid reactants are broken into smaller pieces.
A catalyst is used.</span>
Momentum is a product of velocity and mass thus if the velocity doubles, the momentum also doubles.
20000kgm/s*2=40000kgm/s
Choice-B is a good description of the newton
some positions are quarterback, offence, defense, linebacker, and wider receiver hoped it helped :)
Answer:
<em>P = 1.8 Watt</em>
Explanation:
<u>Electromotive Force (EMF)</u>
It consists of a DC source ε with small internal resistance Ri. When it's connected to an external resistance Re a current i flows by the circuit whose value is given by:

The internal resistance of the battery is Ri=1 ohm and its emf is ε=12 V. When connected to an external resistance of Re=79 ohm, the current is:

i = 0.15 A
The power delivered by the battery is:
P = ε.i
P = 12 V * 0.15 A
P = 1.8 Watt
