A 40-db sound wave strikes an eardrum whose area is 5.0×10^-5 m². A)How much energy is absorbed by the eardrum

per second? B)At this rate, how long would it take yur eardrum to recieve a total energy of 1.0J? Please show work! Thank you*
See the ref. Decibels are an expression of sound intensity (power/area) relative to a reference value.
Db = 10*log10(I/I0), where I = intensity and I0 = ref. intensity
I0 = 1E-12 w/m^2
At 40 [...]

What is another way to find the area of a circle?

I’m really stuck on my maths homework I need to find some ways to finding the area of a circle. Can somebody please help me!?
The area of a circle is pi*r^2, read as: pi-r-squared. Another way, is if you know the radius and circumference, the area of a circle is also equal to circumference [...]

What happens to the volume and surface area of a triangle when a leg is rotated?

The measures of the sides of right triangle ABC are 7mm, 24mm, and 25mm. If triangle ABC is rotated about its shorter leg, what is the volume and area of the figure formed?
The shape formed is called a cone.
The area of a cone is Pi x radius x length of slope
The Volume of [...]

What’s the surface area formula of the triangular prism?

The formula of the triangular prism
It’s the area of the two triangular bases plus the area of the three rectangular sides.
You would need to provide some sample dimensions so we could answer this fully.
