A bottle of a certain type of salad dressing can be considered to be a mixture of olive oil and vinegar. The oil has a density o

f 0.92 g/cm3 and the vinegar has a density of 1.01 g/cm3 . If an unopened and unshaken bottle of dressing contains 3 in. of oil on top of 5 in. of vinegar, find the pressure distribution in the salad dressing bottle before it is shaken. What is the pressure distribution after the bottle is shaken?

Answer:

1.) 183.21 Pascal, 125.7 Pascal

2.) 192.17 Pascal

Explanation:

Given that the oil has a density of 0.92 g/cm3 and the vinegar has a density of 1.01 g/cm3 .

If an unopened and unshaken bottle of dressing contains 3 in. of oil on top of 5 in. of vinegar, convert the inches to cm

1 inch = 2.54 cm

3 inches = 2.54 × 3 = 7.62 cm

5 inches = 2.54 × 5 = 12.7 cm

For oil:

P = dgh

Where

P = pressure

d = density

g = acceleration due to gravity

h = height

P = 0.92 × 9.8 × (7.62 + 12.7)

P = 0.92 × 9.8 × 20.32

P = 183.21 Pascal

For vinegar:

P = 1.01 × 9.8 × 12.7

P = 125.7 Pascal

The pressure distribution after the bottle is shaken will be

P = (1.01 + 0.92)/2 × 9.8 × 20.32

P = 0.965 × 9.8 × 20.32

P = 192.17 Pascal

14.A 90 kg quarterback gets tackled by being hit by a 120 kg lineman backwards
quester [9]

The acceleration of the quarterback and the lineman is 5.55m/s² and 4.16m/s² respectively in the same direction.

As, we know, the 120 Kg lineman is moving with a force of 500N.

His net acceleration will be in the same direction as his motion.

It is already known that, If M is the mass of the body and a is the acceleration of the body, then the force F on the body can be calculated by using the formula,

F = Ma.

The weight of the quarterback is 90 Kg. He is being hit by a force of 500N.

So, the acceleration can be calculated using the formula,

500N = 90kg x a

a = 5.55 m/s².

Now, the weight if the lineman is 120kg, the force applied by him is 500N.

So, from the formula, his acceleration A will be,

500N = 120Kg x A

A = 4.16 m/s².

both of them will have acceleration in the same direction,
