R = V/I

R = 6v / 0.0015 A

R = 4,000 ohms

When n liters of fuel were added to a tank that was already 1 3 full, the tank was filled to 7 9 of its capacity. In terms of n,
Zarrin [17]

Answer: 9/4n

Explanation:

Let's take T to represent tank

When n litres of fuel was added to tank that was 1/3 full = n + 1/3T

The tank was 7/9T

n+1/3T = 7/9T

n =7/9T - 1/3T

n = 4/9

If a full tank is taken to be 1 = 9/9

Hence, we will have 1 = x × n

1 = x × 4/9

x = 9/4

Hence 9/4 of n = 9/4n

Describe matter and explain why light is not matter. Is light made of atoms and elements?
ipn [44]
Matter is a thing. ex: paper. notice how paper can be written on. notice how it is ...well, THERE. now notice light. the light is not atoms. it is electricity that does weird stuff to create a big enough source of energy to be a source of light. sorta like fireflies

If the thermal energy of the system increases by 400 J, and 1,100 J of heat were added to the system, how much work did the syst
Luba_88 [7]

700 J is the work done by the system.

<u>Explanation:</u>

The first law of thermodynamics is that the change in internal energy of the system is equal to the net heat transfer to the system minus the complete work performed by the system.

                  \Delta \boldsymbol{U}=\boldsymbol{Q}-\boldsymbol{W}

Where,

∆U – Change in internal energy

Q – Heat transfer to the system

Q – Work done

Here,

<u>Given data:</u>

∆U - 400 J

Q - 1100 J

We need to the work done by the system (W)

By applying the given values in the above equation, we get

400 = 1100 - W

W = 1100 - 400 = 700 J
