Which object will be move fast.
​

Answer 1

Answer:

hey! complete you question please

Explanation:

If you add water to concentrated sulfuric acid, it can boil and spit and you may get a nasty acid burn. ... The spitting or splashing of acid that results from mixing them in the incorrect order is from the intense heat produced by delayed boiling

Answer 2

Heavier objects move so fast.

If you have two balls which look the same, but have different masses, which will be the first to reach the ground?
People often believe that the heavier ball will fall more quickly. They think that gravity acts more on a heavier object thus pulling it down faster. In fact, gravity works independently of mass. This means that all objects should fall at the same rate. Galileo is said to have tested this idea by dropping balls of different mass from the Leaning Tower of Pisa.
In practice the speed that objects fall may vary, because air resistance will act on objects pushing them up slightly, in opposition to gravity. The greater the surface areas of an object the more surface for air to push up against and so air resistance will act upon a falling object, slowing its fall. The amount of air resistance acting upon something is dependent upon its shape and size. A large parachute slows the fall of a person, bringing them slowly to the ground. If there is no air resistance, or the same amount of air resistance, then objects of the same mass will fall at the same rate
