Answer
Total force exerted by brake cylinders is 249.69 N
Explanation:
We have given that force 
And area of the cylinders 
We have to find the total force
We have given total surface area 
From pascal's law we know that 
And we know that 
So 
Answer:
D.) perpendicular to the current
i am 100% sure :)
Explanation:
formation of compounds because the electric forces compel the atoms to attract each other and formed bonds which leads to the formation of chemical compounds. The attractive or repulsive interaction between any two charged bodies is known as an electric force so the attraction between two opposite charged atoms causes the formation of compounds so we can conclude that electric forces are important for the formation of compounds.
Answer:
D. the distance and direction to the water fountain
Explanation:
To describe the position of a water fountain relative to where one is standing, the distance and direction to the water fountain must be known.
This quantity is known as the displacement.
- Displacement is a vector quantity with both magnitude and direction.
- To specify the magnitude of a displacement, we use the length of path and in this case the height or sometimes the distance.
- The direction attribute distinguishes distance from displacement
- The perfect quantity to solve this problem is the displacement and it specifies the distance of the path and the direction traveled.
