To find the average, add the cost of each book to get a total cost, then divide the total cost by the number of books purchased.


Total cost: 32 + 45 + 39 = 116


Average cost: 116 / 3 = 38.67

When water freezes, its volume increases by 9.05% (that is, δv/v0 = 9.05 10-2). what force per unit area is water capable of exe
vitfil [10]
Given:
K = 2.2 x 10⁹ N/m², the bulk modulus of water
ε = δV/V₀ = 9.05 x 10⁻², the dilatation (volumetric strain)

Let the pressure created by the ice due to volumetric expansion be P.
By definition,
\frac{P}{(\delta V/V)} =K
Therefore
P = (9.05 x 10⁻²) * (2.2 x 10⁹ N/m²) = 1.99 x 10⁸ Pa = 199 MPa
The pressure is 199 MPa or 1.99 x 10⁸ Pa
Note that 1 Pa = 1 N/m²

Answer:  1.99 x 10⁸

Answer:

x=27.80

Step-by-step explanation:

we know that cosA=base/hypotaneous

so,

cos44 =  \frac{20}{x}  \\ x =  \frac{20}{cos(44)}  \\  =  \frac{20}{0.7193...} \\  = 27.80

Answer:

a concave lens is exactly the opppostie with outer surfaces  curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses. ... The distance from the center of the lens to the focal point is, again, the focal length of the lens.
