Pascal's principle
Explanation:
Pascal principle states that "a change in pressure at any point in a fluid in a closed container is transmitted equally and unchanged in all directions throughout the fluid".
Pascal principle is used to solve for the pressures in fluid.
- Hydraulic lift works on pascal principle.
- Pascal principle suggests that a pressure change in an enclosed fluid is transmitted uniformly to all of its parts.
- The principle was established by Mathematician Blaise Pascal

Answer:
A. 19.8 cm.
Explanation:
The apparent depth of the combination is
As it mentioned that the two clear but non-mixing liquid having depth of 15 cm that placed in a glass container together
Also the refractive indices would be 1.75 and 1.33
Based on the above information
As we know that
Refractive indices = real depth ÷ apparent depth
1.33 ÷ 1.75 = 15 ÷ apparent depth
So, it would be 19.736842 cm
Now the combination of apparent depth would be
= ( 19.736842 + 15) ÷ (1.75)
= 19.8 cm
hence, the correct option is A.
A = dv/dt = ak
ak = ( 0.0 m/s - 9.0 m/s ) / ( 3 s )
3m/s^2
Answer:
The speed of the truck must be 9.8 ft/s.
The speed of the truck must be 17 ft/s
Explanation:
First, let´s calculate the distance of the car relative to the intersection at time t = 2 s and t = 6 s:
d(t) = 1.1 t² + t +2
d(2) = 1.1 (2)² + 2 + 2 = 8.40 ft
d(6) = 1.1(6)² + 6 + 2 = 47. 6 ft
The car traveled (47.6 ft - 8.40 ft) 39.2 ft in 4 seconds.
Then, the speed of the truck must be (39.2 ft / 4 s) 9.8 ft/s to cover the same distance as the car in 4 seconds.
Now, let´s find the distance of the car to the intersection at time t = 7 and t = 7.1.
d(7) = 1.1(7)² + 7 + 2 = 62.9 ft
d(7.1) = 1.1(7.1)² + 7.1 + 2 = 64.6 ft
The distance traveled by the car in 0.1 s is ( 64.6 ft - 62.9 ft) 1.7 ft
Then the truck must travel with a velocity of (1.7 ft /0.1s) 17 ft/s to cover that distance in 0.1 s.
