Answer:

b) The more could in the solenoid of the primary loop of a transformer will induce a greater emf in the secondary loop.

Explanation:

I think what that option was saying was the closer to the magnet the solenoid is, the faster it is going and the greater is the magnetic field due to the magnet in the vicinity of the solenoid, so the emf increases.

Answer: The correct answer is : b) The more could in the solenoid of the primary loop of a transformer will induce greater emf in the secondary loop.

Explanation: The flow through a circuit often varies over time as a result of the variable currents that exist in nearby circuits. An induced fem is produced through the so-called mutual induction.

The main offenders in terms of greenhouse gas emissions are?

Mandarinka [93]

The main offenders in terms of greenhouse gas emissions are Asia and Oceania.

<h3>Explanation</h3>

Greenhouse gases cause the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone.

Asia is Earth's largest and most populous continent, located primarily in the Eastern and Northern Hemispheres. Whereas Oceania is a geographic region that includes Australasia, Melanesia, Micronesia and Polynesia.

Asia includes: Bangladesh, China, India, Indonesia, Iraq, Mongolia, Philippines, Sri Lanka and Vietnam. Asia has three main financial centers: Hong Kong, Tokyo and Singapore.

Oceania countries are: Australia, Fiji, Kiribati, Marshall Islands, Micronesia, Nauru, New Zealand, Palau, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu and Vanuatu

Currently, most of factories that exist in the world are established within Asian and Oceanian region because they have good supply of cheap labours. For example, China was initially one of the lowest labour cost countries known. They produce the largest amount of pollutant which contain CO2 that contributed greatly to the greenhouse effects.

Hope it helps

The downward acceleration of a falling body on Earth is 9.81m/s2. On the moon the same quantity is 1.62m/s2. An astronaut in a s

Bas_tet [7]

The astronaut's mass doesn't change. It's the same wherever he goes,
because it doesn't depend on what else is around him.

His weight depends on what else is near him, so it changes, depending
on where he is.

   Weight = (mass) x (gravity)

On Earth, Weight = (145 kg) x (9.81 m/s²) = 1,422.5 newtons.
   (about 320 pounds)

On the moon, Weight = (145 kg) x (1.62 m/s²) = 234.9 newtons.
   (about 53 pounds)
