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.
Answer:
Since Alice has a greater density it will also have a greater mass
Density = mass / volume
The potential energy at the surface of Alice will be greater and a higher kinetic energy will be required to escape the planet's gravitational pull.
PE = K M / R potential at surface is greater because mass is greater
KE = 1/2 M v^2 greater velocity required to overcome PE
Answer: B 2V
Explanation:
Since the voltage of the battery is 2V.
At point A and B, there is no voltage drop. So the voltage will still be same as in the battery which is 2V.
As per bernoulli's principle
here
= pressure upwards
= pressure downwards
= velocity of air upwards
= velocity of air downwards
now from this equation we can say that the pressure difference will be
now the force due to this pressure difference will be
so this is the above force which is given above
Let be the distance between the base of the ladder and the bottom of the wall, and the distance between the top of the ladder and the bottom of the wall, so that
Differentiate both sides with respect to time :
When , the top of the ladder is
above the ground. Then, given that the bottom of the ladder slides away from the wall at a rate of , we have
That is, the top of the ladder is sliding downward at a rate of 0.24 ft/s.
