Answer:
c.) 25 N
Explanation:
We find the volume of the brick, knowing that the volume of a cube is given by the formula:
![l=0,1 metros \\V=l^{3}\\V=(0,1\: \: m)^{3}=0,001\: \: m^{3}](https://tex.z-dn.net/?f=l%3D0%2C1%20metros%20%5C%5CV%3Dl%5E%7B3%7D%5C%5CV%3D%280%2C1%5C%3A%20%5C%3A%20m%29%5E%7B3%7D%3D0%2C001%5C%3A%20%5C%3A%20m%5E%7B3%7D)
being l the side of the cube, which in this case is 10 cm or 0,1 m. Now we find the mass of the object, knowing the density and the Volume of the cube:
![m=V*d\\m=(0,001 \:\:m^{3})(2500 \: \: \frac{Kg}{m^{3}})=2,5 \:\: Kg](https://tex.z-dn.net/?f=m%3DV%2Ad%5C%5Cm%3D%280%2C001%20%5C%3A%5C%3Am%5E%7B3%7D%29%282500%20%5C%3A%20%5C%3A%20%5Cfrac%7BKg%7D%7Bm%5E%7B3%7D%7D%29%3D2%2C5%20%5C%3A%5C%3A%20Kg)
We find the weight by multiplying the mass of the object with the gravity constant.
![W=m*g=(2.5 \:Kg)*(9,81 \:m/s^{2} )=24,5 N\approx25\: N](https://tex.z-dn.net/?f=W%3Dm%2Ag%3D%282.5%20%5C%3AKg%29%2A%289%2C81%20%5C%3Am%2Fs%5E%7B2%7D%20%29%3D24%2C5%20N%5Capprox25%5C%3A%20N)
The answer is B. One plate slides past another.
The San Andreas Fault in California and the Alpine Fault in New Zealand are examples of transform boundaries.
Hope this helps! :)

18. a land breeze is a breeze blowing towards the sea
Answer:
C
Explanation:
b is 55 miles per hour south or 55mph[South]
the important part to understand is that velocity is a vector meaning it also has to have a direction, in this case south. That is why a (2m/s) is not a velocity, however 2m/s is a speed.
