Question 29 1 pts Which of the following are primarily due to Bernoulli's Principle? (Choose all that apply) Dropping objects not accelerating with the full acceleration due to gravity, $g$. Baseballs curving when spinning Being able to raise a large mass using a hydraulic jack. Umbrellas turning inside out when windy

Step 1 ：This question is about Bernoulli's Principle, which is a principle in fluid dynamics that states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.

Step 2 ：The options given are: 1. Dropping objects not accelerating with the full acceleration due to gravity, $g$. 2. Baseballs curving when spinning 3. Being able to raise a large mass using a hydraulic jack. 4. Umbrellas turning inside out when windy

Step 3 ：Analyzing each option: 1. Dropping objects not accelerating with the full acceleration due to gravity, $g$. This is more related to the principle of gravity rather than Bernoulli's Principle.

Step 4 ：2. Baseballs curving when spinning. This is a phenomenon known as the Magnus effect, which is indeed related to Bernoulli's Principle. The spinning of the baseball creates a pressure differential, causing it to curve.

Step 5 ：3. Being able to raise a large mass using a hydraulic jack. This is more related to Pascal's Principle, which states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.

Step 6 ：4. Umbrellas turning inside out when windy. This is due to the Bernoulli's Principle. The wind moving over the top of the umbrella creates a low pressure area, and the higher pressure underneath the umbrella pushes it upwards, causing it to turn inside out.

Step 7 ：The phenomena primarily due to Bernoulli's Principle are \(\boxed{\text{Baseballs curving when spinning and Umbrellas turning inside out when windy}}\).
