Light hits a clear plastic bottle and a granite rock. Which choice most accurately describes the effect of visible light on the

clear plastic and a grey rock?
1. Visible light is absorbed by both the rock and the plastic, making both objects warmer. Visible light is also reemitted by both objects, allowing visible light through the rock and the plastic.

2. Visible light is absorbed by both the rock and the plastic, making both objects warmer. Some of the light hitting the rock is reemitted, allowing visible light through the rock. None of the light hitting the plastic is reemitted.

3. Visible light is absorbed by the rock, making it warmer. Light is also absorbed by the plastic making it warmer. None of the light hitting either object is reemitted.

4.Visible light is absorbed by the rock and the plastic making both objects warmer. Some of the light hitting the plastic is reemitted, allowing visible light through the plastic. None of the light hitting the rock is reemitted.

Answer:

4

Explanation:

When the light hits an object, it is absorbed, and the energy of it is transferred by the object by heat, thus it warms. When the object is dark the light is not reemitted because the absorption factor of dark color is almost 100%. But, for clear objects, the absorption factor is small, does, some of the light must be reemitted through it.

Sketch a position-time graph for a bear starting
Dmitrij [34]

Explanation:

hopefully that makes sense. the position doesn't change over the 5 seconds, meaning it's stopped but time still continues. then when the slope is negative this shows the bear's position becoming negative (backing up, changing direction).

Football player A has a mass of 210 pounds and is running at a rate of 5.0 mi/hr. He collides with player B. Player B has a mass
Naddika [18.5K]

The equation for momentum is p = mv where p is the omentum, m is the mass and v is the velocity. Calculating the momentum for each football player, player A will have a momentum of 1050 lb-mi/h and player B will have a momentum of 570 lb-mi/h. Therefore, momentum of player A is greater than that of player B.

Two students, sitting on frictionless carts, push against each other. Both are initially at rest and the mass of student 1 and t
Zepler [3.9K]

Answer:

  v₂ = v/1.5= 0.667 v

Explanation:

For this exercise we will use the conservation of the moment, for this we will define a system formed by the two students and the cars, for this isolated system the forces during the contact are internal, therefore the moment conserves.

Initial moment before pushing

    p₀ = 0

Final moment after they have been pushed

    p_{f} = m₁ v₁ + m₂ v₂

   p₀ =  p_{f}

   0 = m₁ v₁ + m₂ v₂

   m₁ v₁ = - m₂ v₂

Let's replace

   M (-v) = -1.5M v₂

   v₂ = v / 1.5

  v₂ = 0.667 v

zheka24 [161]

Answer:

The speed is 173 m/s.

Explanation:

Given that,

A = 47

B = 14

Length 1 urk = 58.0 m

An hour is divided into 125 time units named dorts.

3600 s = 125 dots

dorts = 28.8 s

Speed v= (25.0+A+B) urks/dort

We need to convert the speed into meters per second

Put the value of A and B into the speed

v=25.0+47+14

v =86\ urk s/dort

v=86\times\dfrac{58.0}{28.8}

v=173.19\ m/s

Hence, The speed is 173 m/s.
