1 answer:

4 0

Solids have one static volume and shape and particles of solids move a short distance, practically against each other, before hitting one another.

Liquids fill the volume and take the shape of the container they are placed in and particles move a longer distance before hitting one another and bouncing back to each other

Gases fill shape and volume of their container and their particles move freely about a larger space than either solid or liquid and hit one another bouncing

"A bicycle's brakes apply 299 N of frictional force to the wheels as the bike moves 24 m

Usimov [2.4K]

Answer:

0.62 N

Explanation:

first of all: 3.0 s = 0.05 m

Let ? be the work that brakes do at 3.0s

24 m ----> 299 N

0.05 m ---->?

? = (0.05 m x 299 N)/ 24

? = (14.95)/ 24

? = 0.622 N

Give the nuclear symbol for the isotope of gallium, ga, that contains 40 neutrons per atom. Replace the question marks with the

Cerrena [4.2K]

The nuclear symbol of an element have three parts namely:

the symbol of an element
mass number of the element
atomic number of the element

The general representation is as:

$_{Z}^{A}X$

where X is the chemical symbol of the element, A is mass number of the element that is total number of neutrons and protons in the nucleus of an atom, and Z is atomic number of the element that is number of protons in the atom.

Element = Gallium, $Ga$ (given)
