Why does your reflection in a mirror look different from your reflection in wood

1 answer:

5 0

The light will reflect off the mirror in a more orderly way than it reflects off your clothes. We call that specular reflection—it's the opposite to diffuse reflection. ... The silver atoms behind the glass absorb the photons of incoming light energy and become excited. (This answer is from google to try and put it in your own words)

The radius of the cone id 1.75 inches an the height id 3.5 inches. If the diameter of the bubble gum ball is 0.5 inches what is

Olegator [25]

Answer: $11.15 in^{3}$

Explanation:

We need to know the volume of the cone that can be filled with bubble gum ball, but firstly we need to calculate the volume of the cone $V_{C}$ and the volume of the buble gum ball (a sphere) $V_{B}$ :

Volume of the cone:

$V_{C}=\frac{\pi R^{2}h}{3}$ (1)

Where:

$R=1.75 in$ is the radius of the cone

$h=3.5 in$ is the height of the cone

$V_{C}=\frac{\pi (1.75 in)^{2}3.5 in}{3}$ (2)

$V_{C}=11.22 in^{3}$ (3) This is the volume of the cone

Volume of the gum ball:

$V_{B}=\frac{4\pi r^{3}}{3}$ (4)

Where:

$r=\frac{0.5 in}{2}=0.25 in$ is the radius of the sphere (half the diameter)

$V_{B}=\frac{4\pi (0.25 in)^{3}}{3}$ (5)

$V_{B}=0.065 in^{3}$ (6) This is the volume of the gum ball

Know we are able to find the closest approximation of the volume of the cone that can be filled with bubble gum ball, by calculating the difference or substracting (6) from (3):

$V_{C}-V_{B}=11.22 in^{3}-0.065 in^{3}$ (7)

Finally:

$V_{C}-V_{B}=11.15 in^{3}$ (8)

How does paleomagnetism support the theory of plate tectonics.

gregori [183]

Answer:

Paleomagnetism also provides evidence to support theories in plate tectonics. Because the ocean floor is mostly composed of basalt, an iron-rich substance containing minerals that align with the magnetic field, they record the alignment of the magnetic fields surrounding oceanic ridges.
