sac
hole
Answer: sac
Tunicates are sea squirts that are found in the marine water. These animals remain attached to the rocks and sea beds. They exhibit a body shape which looks like a barrel. The barrel has two openings called siphons. These siphon helps in the intake of the food particles and oxygen. These animals look like a sac on the sea floor.
Hope this helps :)
The car reaches its top speed when the constant thrust force equals the opposing air resistance force, resulting in zero net external force and constant velocity. This balance between thrust and resistance forces determines the top speed.
When the applied thrust force typically supplied by the engine equals the total of the opposing forces pushing on the vehicle, the vehicle reaches its maximum speed.
Air resistance, or drag, is the main opposing force and it grows as the car's speed squares. The car first accelerates because the propulsion force overcomes this resistance as it accelerates. But the air resistance force likewise increases with the car's speed until it reaches the same level as the thrust force.
The car now maintains a steady velocity when it reaches its maximum speed and the net external force acting on it zeroes. The maximum speed is also influenced by other elements like mechanical efficiency and rolling resistance.

The s, p, d, and f orbitals are the areas where electrons will be most likely found. These letters give us an idea of the shapes of these formed by the electron clouds. Going by this, a spherical electron cloud surrounding an atomic nucleus would best represent an;
The s Orbital has spherical symmetry and is located around the nucleus of an element.
As there becomes an increase in the energy levels, the size of the orbital increases, leading to the extension of the electrons further away from the nucleus.
The angular quantum number (l) of the s subshell is 0. When fixed into the equation; 2 (2l + 1), the maximum number of electrons that this subshell can hold is 2.

Answer:
a S orbital
Explanation:
Atomic orbitals is the place where we are most likely to find at least one electron, this definition is based on the equation posed by Erwin Schrödinger.
It is said that each electron occupies an atomic orbital that is defined by a series of quantum numbers s, n, ml, ms. In any atom each orbital can contain two electrons. It is possible that thanks to the function of the orbitals, the appearance that atoms can have is that of a diffuse cloud.
The orbitals s (l = 0) have a spherical shape. The extent of this orbital depends on the value of the main quantum number, so a 3s orbital has the same shape but is larger than a 2s orbital.
The orbitals p (l = 1) are formed by two identical lobes that project along an axis. The junction zone of both lobes coincides with the atomic nucleus. There are three orbitals p (m = -1, m = 0 and m = + 1) in the same way, which differ only in their orientation along the x, y or z axes.
The orbitals d (l = 2) are also formed by lobes. There are five types of d orbitals (corresponding to m = -2, -1, 0, 1, 2)
b. The watermelon will fall faster than the other two.
c. The orange will fall the fastest, followed by the watermelon and then the feather.
d. The feather will fall faster than the orange, which will fall faster than the watermelon.
