Answer:
The diameter of the hose is 0.326 mm.
Explanation:
Given that,
Speed of car = 28 miles/galllon
We need to calculate the radius
The rate of flow of fluid is from the equation of continuity
Where, A = area of cross sectional
We know that,
The velocity is the ratio of displacement of gas per unit time.
Put the value into the formula
We need to calculate the diameter of the hose
Put the value of r
Hence, The diameter of the hose is 0.326 mm.
C. This is the idea of "black body radiation". Charcoal/carbon is a "perfect black body". Absorbs all radiation. There's a whole host of stuff about this in physics, including, I think, Planck's (Nobel Prize winner) black body radiation theory.
When an object's atoms move faster, its thermal energy increases and the object becomes warmer.
Answer: False
Explanation: The sun is one of earths primary energy sources. Without the sun, all animals, plants, humans would die. The sun's energy provides warmth for humans and plants and animals cannot grow without the sun.
Maybe show a picture ? I don’t get the question .
