Answer:
ossicles (comprising of hammer, anvil, and stirrup)
Explanation:
The hammer, anvil and stirrup are also known as the malleus, incus, and stapes, respectively which are the part of the middle ear.
They transmit the sound vibrations from eardrum to cochlea by a level mechanism. The generate mechanical advantage by multiplying the force over a shorter distance from the input of a smaller force at a larger distance.
The answer would be B: The ground exerts an equal force on the golf ball.
Answer:
0.25 m
Explanation:
Refraction occurs when the velocity or wavelength of a wave changes at the interface between two media.
We know that refractive index=
Wavelength in medium A/wavelength in medium B = velocity in medium A/velocity in medium B
Let the wavelength of medium B be a
0.5/a = 0.3/0.15
0.5 × 0.15 = 0.3 × a
a= 0.5 × 0.15/0.3
a= 0.25 m
Explanation:
Hence from liquid to solid or solid to liquid the transition has to cross the grey zone. This grey zone transition is is very crucial which includes the inter molecular forces acting on the molecules and each atoms which makes the change in state from hot to cold and cold to hot.
Answer:
<h2>
$228</h2>
Explanation:
Given data
Total electricity consumption = 2400 kWh
Rate of consumption = 9.5 cent per kWh
converting cent to dollar we have. 9.5/100= $0.095
hence the bill is 2400*0.095= $228
