For light 3 to function, switch D does not have to be on. This diagram shows a parallel circuit that provides more than one way for the current to return to the power source.

1/ Which graph illustrates constant speed and velocity
Maksim231197 [3]
Velocity is said to be constant if its magnitude as well direction at any instant is remains the same. In D, if you draw a line parallel to y-axis at any time t, you can see that velocity is same. Hence, D is the correct graph.

The kinetic energy of gaseous molecules is greater than that of liquid molecules. Therefore, in gas, kinetic energy overcomes the force of attraction between molecules. In short, in gas phase, particles move at high speed and hence they have less force of attraction. In case of liquid phase, particles are close enough as a result there is much more force of attraction compared to gaseous molecules. In liquid state, kinetic energy cannot overcome force of attraction therefore, liquid molecules slow down.

Therefore, B is the correct answer.

How do gas particles respond to an increase in volume?
wariber [46]
An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure.

What is the number of molecules in<br> 500m cube of Oxygen at room temperature
d1i1m1o1n [39]

4.95 is the number of molecules in 500m cube of Oxygen at room temperature and pressure

we have got data

pressure=1atm

temperature=298 k

volume=500 m^3

gas constant, R=8.31

now, by applying ideal gas equation

PV=nRT

1×500=n×8.31×298

n=2476.38/500

n=4.95

It is the lowest part of the material and has chemical elemental properties. Atoms do not independently exist; rather, they combine to form ions and molecules, which then combine to form the material that we can see, feel, and touch.

Molecules are made up of one or more atoms connected by covalent (chemical) connections. Atoms can be visualized as circles with a nucleus in the center (made up of protons and neutrons) and one or more concentric circles around it that indicate the "shells" or "levels" in which the electrons surrounding the atom's nucleus are located, as well as markings that identify the electron. each level

Name the following compound:
igomit [66]

Answer:

3,5-dimethyl-2-octene

Explanation:

When naming an organic molecule with a double bond, the chain has to include the double bond.  This means that there are 8 carbon atoms on the central chain.  The molecule is octene.  The double bond is after the second carbon, making it 2-octene.  You can't say that its 6-octene because you want to have the smallest number possible in front.

The molecules attached are two methyl groups.  Since you have two methyl groups, the name will be dimethyl.  Start counting from the side closest to the double bond.  This gives you a 3, 5-dimethyl group.
