Conductive deafness occurs Because of damage to what part of the body

aliya0001 [1]

Conductive deafness refers to a malfunction of the middle ear. Those 3 ossicles (malleus, incus, stapes) are responsible for converting the sound wave and conducting it to the inner ear.

Suppose a log's mass is 5kg. After burning, the mass of the ash is 1 kg. Explain what could have happened to the other 4kg.

snow_lady [41]

Mass never just disappears. The other 4kg had to go somewhere. It could have left the scene of the fire in the form of smoke particles and hot gases.

1.) Identify two types of heat?

inn [45]

Answer:

Explanation:

Thermal Energy and Heat

Shards of ice fly from the sculptor’s chisel. As the crowd

looks on, a swan slowly emerges from a massive block of ice. As

the day wears on, however, drops of water begin to fall from the

sculpture. Drip by drip, the sculpture is transformed into a puddle of liquid water. What makes matter change from one state to

another? To answer this question, you need to think about the

particles that make up matter.

Energy Simply stated, energy is the ability to do work or cause

change. The energy of motion is called kinetic energy. Particles

within matter are in constant motion. The amount of motion of

these particles depends on the kinetic energy they possess. Particles

with more kinetic energy move faster and farther apart. Particles

with less energy move more slowly and stay closer together.

The total kinetic energy of all the particles in a sample of

matter is called thermal energy. Thermal energy, an extensive

property, depends on the number of particles in a substance as

well as the amount of energy each particle has. If either the

number of particles or the amount of energy in each particle

changes, the thermal energy of the sample changes. With identically sized samples, the warmer substance has the greater thermal energy.

The intensity of sunlight reaching the earth is 1360 w/m2. Assuming all the sunligh is absorbed, what is the radiation pressure

krok68 [10]

(a) $1.15\cdot 10^9 N$

For an electromagnetic wave incident on a surface, the radiation pressure is given by (assuming all the radiation is absorbed)

$p=\frac{I}{c}$

where

I is the intensity

c is the speed of light

In this problem, $I=1360 W/m^2$ ; substituting this value, we find the radiation pressure:

$p=\frac{1360 W/m^2}{3\cdot 10^8 m/s}=4.5\cdot 10^{-6} Pa$

the force exerted on the Earth depends on the surface considered. Assuming that the sunlight hits half of the Earth's surface (the half illuminated by the Sun), we have to consider the area of a hemisphere, which is

$A=2pi R^2$
