Atomic mass = protons + neutrons

So the total number of protons and neutrons

stellarik [79]3 years ago

3 0

Answer:

the total number of its protons and neutrons

Explanation:

An atom is represented by

$_z^AX$

here we know that

z = atomic number

it represent the total number of protons or total number of electrons present in an neutral atom

A = mass number

it represents the total number of neutrons and protons present inside the nuclei of an atom

this is also known as atomic mass of an atom in amu (atomic mass unit)

What is Newton’s second law of motion

ddd [48]

"F = dP/dt. The net force acting on an object is equal to the rate at which its momentum changes."

These days, we break up "the rate at which momentum changes" into its units, and then re-combine them in a slightly different way. So the way WE express and use the 2nd law of motion is

"F = m·A. The net force on an object is equal to the product of the object's mass and its acceleration."

The two statements say exactly the same thing. You can take either one and work out the other one from it, just by working with the units.

What force is required to accelerate a body with a mass of 15 kilograms at a rate of 8 m/s²?

mihalych1998 [28]

Newton's Second law of motion:

Force = (mass) x (acceleration)

Force = (15kg) x (8m/s²) = 120 kg-m/s² = 120 newtons

As the Sun ages, what will happen to life here on Earth? Why?

Burka [1]

Answer:

As the Sun ages it will enter another stage of stellar evolution where it's atmosphere begins to inflate.As the Sun heats up and expands, life on Earth will become increasingly difficult. Long before the Sun becomes a red giant some 4 or 5 billion years from now, our planet will be rendered uninhabitable.

A hiker walks due East for a distance of 6 km

solniwko [45]

Resultant displacement between the base camp and the cave will be 7.211 km

Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

Her resultant displacement can be calculated using Pythagoras theorem

$H^{2} = P^{2} + B^{2}$
