Answer: The outer core is liquid and moving.

Earth’s core is composed of iron and nickel.

Explanation:

A magnetic field is produced by a magnetic material such as Iron, Cobalt or Nickel. Magnetic field are magnetic lines of force i.e. the region which experiences magnetic force. Earth acts as a huge bar magnet and has magnetic field around it due to which we are shielded by solar particles and experience phenomenon such as Auroras.

The earth acts as bar magnet due to presence of iron and nickel in molten form in its core. The outer core is liquid and moves generating a magnetic field. Thus, the correct options are:

The outer core is liquid and moving.

Earth’s core is composed of iron and nickel.

All the statements can be used to explain about Earth's magnetic field.

Earth's magnetic field is almost same to that of the bar magnet. The magnetic field of the earth occurs from its core. It has an inner core which is solid in nature. in the outer core, there is a motion of the liquid due to heat flow from the inner core to the core mantle boundary which proves that the outer core is liquid and moving. The Earth's core consists of iron and nickel as the Eddy currents in the iron and nickel liquid helps generating the Earth's magnetic field.

Hence, all the three statements are true and can be used to explain the Earth's magnetic field.

A large truck is moving at 22.0 m/s. if its momentum is 125,000 kg • meters per second, what is the truck's mass? 176 kg 2750 kg
solong [7]

The  mass of the large truck is determined as 5680 kg.

<h3>Mass of the truck</h3>

The mass of the truck is calculated as follows;

P = mv

where;

  • P is momentum
  • m is mass
  • v is velocity

m = P/v

m = 125000/22

m = 5680 kg

Thus, the  mass of the large truck is determined as 5680 kg.

According to the graph, what is the motorcycle’s Average velocity ?
borishaifa [10]
According to the position vs time graph, the <em>average</em> <em>velocity</em> of the motorcycle is the change in position divided by the change in time. Also, note that the slope is linear and positive throughout the 5 hours, it doesn't change direction. 

Therefore, we have
Avg velocity = change in direction/change in time
Avg velocity = (150km - 30km)/(5h - 0h)
Avg velocity = 24km/hr south.

Why do we tend to attribute others' negative behaviors to dispositions over situational factors?
miskamm [114]

Answer:

Because you have a greater understanding of the mentality and conduct of individuals you care about, you are better able to understand their perspective and are more likely to recognize possible situational factors for their behavior.
