An older brother pours all the water out of a small cup on his little brother's head. Later, the little brother pours all the water out of a large pot on the older brother's head.
Which of the answer choices correctly analyzes the pressure exerted by the water in the scenario?
The water from the large pot exerted more pressure because the little brother had less strength.
The water from the small cup exerted more pressure because it had less mass.
The water from the large pot exerted more pressure because it had more mass.
The water from the small cup exerted more pressure because the older brother had more strength.
is it c?
looks good
Yes, the correct answer is c. The water from the large pot exerted more pressure because it had more mass.
To understand why this is the correct answer, let's explain how pressure is calculated and what factors affect it.
Pressure is defined as the force exerted on an object per unit area. It is calculated by dividing the force applied on an object by the area over which the force is applied. Mathematically, it can be expressed as: Pressure = Force/Area.
In this scenario, both the small cup and the large pot contained water. The amount of water in each container represents its mass, which is the amount of substance present. Since the large pot had more water, it had a greater mass compared to the small cup.
Now, let's consider the force exerted by the water. The force exerted by a fluid is directly proportional to its mass and the acceleration due to gravity. In this case, the force exerted by the water in each container is the weight of the water, which is mass multiplied by the acceleration due to gravity.
Since the large pot had more water, it means it had a greater mass. Therefore, the force exerted by the water from the large pot was greater than the force exerted by the water from the small cup.
Now, let's talk about why the area over which the force is applied is not a factor in this scenario. The area is the part of the object that the force is distributed over. In this case, both the older brother's head and the little brother's head had similar areas. Therefore, the area factor does not influence the pressure difference between the two scenarios.
To summarize, the water from the large pot exerted more pressure because it had more mass. The strength of the brothers or the area of their heads did not affect the pressure exerted by the water.
