Answer:

Magnetic field strength increases

Explanation:

Winding of wire with current is one of the ways used to increase magnetic field. When the wires are closely wound and current increases, the magnetic strength also increases since the magnetic strength is directly proportional to the number of wire windings. Moreover, increasing the current also enhances the magnetic field strength.

Andrei [34K]

Answer:

<em>C. the blue colour of the Earth's sky</em>

<em></em>

Explanation:

The Pleiades is a cluster of sister stars that are among the closest star cluster to earth.

The reflection nebula of the Pleiades is due to the scattering of the blue light from the hot blue luminous stars that dominate the star cluster. Th blue light is scattered from dust molecules, thought to be predominantly carbon compound like diamond dusts, and other compounds like iron.

The blue colour of the Earth's sky is the closest terrestrial phenomenon to the reflection nebula. On a clear cloudless day, molecules in the air scatter the blue component of light more than the other component colours of white light, giving the sky its characteristic blue coluor.

The common characteristics of the luminous nebula and the Earth's blue sky is that they both have their light scattered by the presence of small particles.

You have a mass of 60-kg, and you are facing your friend who has a mass of 100 kg. You skate towards
White raven [17]

Answer: My initial velocity is 5 m/s.

Explanation:

In this case, momentum can be conserved.

initial momentum = final momentum

Since both the bodies come to rest after collision,

Final momentum = 0

Let my velocity be v, and mass, m1 = 60 kg

Friend's mass, m2 = 100 kg

Friend's velocity, v2 = 3 m/s

Intial momentum = m1v + m2v2

= 60v + 300

Conserving momentum,

60v + 300 = 0

v= -5 m/s

( Negative sign indicates that me and my friend are moving in opposite directions that is towards each other)

netineya [11]

Answer:

Explanation:

All of the planets listed are classified as "Gas Giants" due to them being much larger than the terrestrial rocky planets. They are also strictly composed of gaseous elements such as nitrogen, hydrogen, methane, etc.. Both A and B are correct. I am unsure if you can choose more than one.
