Once energy from the Sun gets to Earth, several things can happen to it:

Energy can be scattered or absorbed by aerosols in the atmosphere. Aerosols are dust, soot, sulfates and nitric oxides. When aerosols absorb energy, the atmosphere becomes warmer. When aerosols scatter energy, the atmosphere is cooled.
Short wavelengths are absorbed by ozone in the stratosphere.
Clouds may act to either reflect energy out to space or absorb energy, trapping it in the atmosphere.
The land and water at Earth's surface may act to either reflect energy or absorb it. Light colored surfaces are more likely to reflect sunlight, while dark surfaces typically absorb the energy, warming the planet.
Albedo is the percentage of the Sun's energy that is reflected back by a surface. Light colored surfaces like ice have a high albedo, while dark colored surfaces tend to have a lower albedo. The buildings and pavement in cities have such a low albedo that cities have been called "heat islands" because they absorb so much energy that they warm up.

A 1400 kg car at rest at a stop sign is rear ended by a 1860 kg truck traveling at a speed of 19.1 m/s. After the collision, the
Anna71 [15]

Answer:

Explanation:

Applying conservation of momentum law to system of car and truck

their common velocity = their total momentum before collision / total mass

= (0 + 1860 x 19.1 ) / (1400 + 1860)

= 10.8975  m/s

Velocity of car with respect to ground before the collision u₁ = 0

velocity of the car in the frame of Alice                 u₁ = 0 - 6.11 = - 6.11 m /s

similarly velocity of truck in the frame of Alice = 19.1 - 6.11 = 12.99 m /s

total momentum of system of car and truck in alice's frame

= m₁ u₁ + m₂u₂  , m₁ , m₂ are masses of car and truck and u₁ , u₂ are their velocities in Alice's frame

= 1400 x - 6.11 + 1860 x 12.99

= - 8554 + 24161.4

= 15607.4 kg m/s

velocity of car and truck  after collision in Alice's frame

= 10.8975 - 6.11

= 4.7875

total momentum after collision in Alice's frame

= 4.7875 x ( 1400 + 1860 )

= 15607.25

Total momentum before collision in Alice's frame

= Total momentum in Alice's frame after collision

So law of conservation of momentum is obeyed in Alice's frame also.

How can I describe an Electric Current?
Sedaia [141]

Answer:

the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire. Aug 29 2019

The energy that generates wind comes from what source?
mamaluj [8]

The energy that generates wind on an individual basis originates with
one's habitual diet.  On a world-wide basis, it comes from the sun.
