Questions are in the picture ^ (please answer separately)

Answers

a: The battery is a store of internal energy (shown as chemical energy). The energy is transferred through the wires to the lamp, which then transfers the energy to the surroundings as light. These are the useful energy transfers - we use electric lamps to light up our rooms.

B: In the case of the light bulb the 95J of energy transferred as heat is wasted energy as it is not useful because the purpose of the device is to produce light.

SORRY I ONLY HAVE ANSWERS FOR A AND B

A.) the light bulb is stored with lots of internal energy

B.) energy transferred as heat is wasted energy as it is not useful because the purpose of the device is to produce light. An ordinary light bulb works on the principle of a thin wire (filament) being heated by the resistance to the electrical current.

It’s called wasted because it’s not necessary at all bc a light bulb soul purpose is that it makes light but bc it makes heat that heat is not necessary so therefore it’s wasted bc that’s not what we are using it

How are electricity and magnets connected?

Answers

Answer:

Magnets are employed to generate electricity.

Explanation:

Magnets' characteristics are employed to generate electricity. Electrons are pulled and pushed by moving magnetic fields. When you move a magnet around a coil of wire, or a coil of wire around a magnet, the electrons in the wire are pushed out and an electrical current is created.

Answer:

they are closely related, because flowing electrons produce some magnetic field and spinning magnets make a flow of electricity, make them interact and it's called electromagnetism

A tin containing 5 litres of paint has a mass of 8.5kg. The empty tin has a mass of 2.0kg. What is the density of the paint?

Answers

Answer:

The density is 1.3 kg per cubic meter

Explanation:

Density is mass divided by volume, so:

8.5-2 = mass of paint (kg)

5 = volume (L)

P = 6.5/5

what is liquidity preferences?

Answers

Liquidity preference, the premium that wealth holders demand for exchanging ready money or bank deposits for safe,

non-liquid assets such as government bonds.

Liquidity Preference Theory is a model that suggests that an investor should demand a higher interest rate or premium on securities with long-term maturities that carry greater risk because, all other factors being equal, investors prefer cash or other highly liquid holdings.

why isn't the coal found distributed evenly around the world??? asap pls

Answers

Coal is founded in regions that had dense forest (mainly rainforests). Fue to natural causes, they gpt buried deep under the ground and due to extreme pressure and temperature, they got converted into coal.

The regions that had relatively less dense forests, have less coal today.

Fossil fuels are distributed unevenly because: Different minerals form in different places. Some deposits have already benn completely used up. Some resources grow back faster than others.

Will two things push on each other with the same amount of force if they are different masses?

Answers

Answer:

Yes.

Explanation:

Yes, both the objects will push each other regardless of different masses but in the opposite direction. Also, the larger object will have a greater force on the smaller as it has more inertia compared to the smaller.
