Why can we still see craters on the moon even though they were formed by ancient meteor collisions?

shepuryov [24]

Because there is no wind, snow, rain, sleet, blowing dust, hail,
or humidity on the moon to smooth them over and fill them in.
Without those things, we'd be able to see all the ancient meteor
collisions on Earth.

Which example identifies a change in motion that produces acceleration? choices are: 1. a speed skater moving at a constant spee

Oduvanchick [21]

Acceleration is a vector quantity that takes into account the changes in either the direction or the velocity or both. From the choices given, I go with choice number 2 where the body moves in a circular motion; thus, causing changes in its direction from time to time.

The point is at the edge of the disk and the component bodies are:

Murrr4er [49]

Answer:

a. A uniform disk of radius and mass .

Explanation:

The moment of inertia I of an object depends on a chosen axis and the mass of the object. Given the axis through the point, the inertia will be drawn from the uniform disc having a radius and the mass.

A compound wall consists of parallel layers of two different materials, 10 cm of brick and 2 cm of wood. If the difference of te

RSB [31]

The temperature difference between the wooden wall is 16⁰C, and the heat current per square metre of the wall is 7,325 W/m².

<h3>Temperature difference between the wooden wall</h3>

The temperature difference between the wooden wall is calculated as follows;

Let the brick wall = wall A
Let the wooden wall = wall B
Let the area of the walls = A

$\frac{dQ_A}{dt } = \frac{dQ_B}{dt} \\\\\frac{K_A \Delta T_A \times A}{L_A} = \frac{K_B \Delta T _B \times A}{L_B}\\\\\frac{K_A \Delta T_A }{L_A} = \frac{K_B \Delta T _B}{L_B}\\\\\frac{0.5 \times 20}{0.1} = \frac{0.125 \times \Delta T _B }{0.02} \\\\100 = 6.25\Delta T _B\\\\\Delta T _B = \frac{100}{6.25} \\\\\Delta T _B = 16 \ ^oC$

<h3 /><h3>Heat flowing in the walls</h3>

Q = KL(ΔT)

Q = 0.5 x 0.1 x (20 + 273)

Q = 14.65 W

<h3>Heat current per square meter of the Walls</h3>

QA = W/A

QA = (14.65)/A

Let the area of the wall = 10 cm x 2 cm = 0.1 m x 0.02 m = 0.002 m².

QA = 14.65/0.002

QA = 7,325 W/m²
