Considering the gravity, The statement D is not correct: Earth's gravity does not keep all the planets spinning around the sun, Sun's gravity does it.
All objects in the universe have a mutual attraction. This attraction is known as gravity. So, the movement of the planets around the Sun is fundamentally due to the force of gravity. Each one has its own orbit and characteristics, but in all cases this is determined by the law of gravitation, which says that the force with which gravity affects bodies depends on two things: the mass of the objects and the distance between them. the objects. As the mass of an object increases, the attraction increases. If the distance between the objects increases, the attraction decreases.
In summary, the Sun keeps the planets spinning thanks to the force of gravity. The planets move around the Sun following paths in the form of an ellipse and each one rotates at a speed that depends on its distance from the Sun: the farther they are from the Sun, the slower they spin.
The statement D is not correct: Earth's gravity does not keep all the planets spinning around the sun, Sun's gravity does it.

Answer: it’s
Earth gravity keeps all the planets spinning around the sun.
Explanation:
Got it right
THe pH of the solution containing NaF and HF would be higher than that of a solution of HF only.
The presence of NaF drives the reaction towards the HF side to reach equilibrium.
The concentration of H+ is higher in an HF solution containing NaF.
The pH of the solution containing NaF and HF would be lower than that of a solution of HF only.
The presence of the dissolved NaF does not affect the HF equilibrium reaction nor the equilibrium concentrations.
The concept of an ideal gas is chiefly used to explain the behavior of a gas sample according to the ideal gas law. It's not primarily used to determine the mass of a gas sample, or whether a gas is monatomic or diatomic.
The concept of an ideal gas is primarily used to explain the behavior of a gas sample. An ideal gas is a theoretical gas composed of randomly moving, non-interacting point particles. It follows the ideal gas law which is PV=nRT, where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the absolute temperature. The ideal gas law allows us to predict how a gas will behave under different conditions of pressure, volume, and temperature.
The mass of a gas sample is inherently tied to the moles of gas, per the molar mass concept in the ideal gas law. As for whether a gas is monatomic or diatomic, this depends on the atomic structure and bonding of the specific gas species, and not the ideal gas concept itself.

Answer:
It could possibly cause damage to the person lighting the firework and would quicken the ignition time.
Explanation:
The purpose of the longer fuse is so the person can run back in enough time to reach safety. Shortening that fuse can cause serious danger. The role of the fuse is to delay ignition.
If the secondary fuse of an aerial firework is too short, the firework would explode prematurely, potentially presenting a danger to operators and spectators.
In the context of aerial fireworks, fuses are critical components that control the timing of explosions. If the secondary fuse in an aerial firework is too short, the firework would explode prematurely, potentially before it even leaves the ground or far below the intended altitude. The short fuse wouldn't provide the requisite delay, which is normally intended to allow the firework to reach its maximum altitude before exploding. This could pose safety risks to those operating the fireworks and the nearby spectators as well.
