Two waves of equal magnitude but opposite phase interfere with one another to cause the waves to disappear. this is caused by: each wave canceling the other out, causing the waves to disappear completely refraction of waves multiplying each other's amplitude with the effect of canceling each other out the conner effect destructive interference giving the effect of making the waves disappear, but each will travel on its way

On a cold day, when the air temperature is 0°c, you empty your lungs and take a deep breath, filling your lungs with 4.2 l of air. if you hold your breath until the temperature of the air in your lungs reaches 37°c, what is the volume of the air in your lungs at that point, assuming the pressure does not change?

Which of the following represents an upside-down image?

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?
