Which of the following is the best definition of an isotope?
ad-work [718]

Answer:

A. elements of the same kind with different numbers of neutrons

Explanation:

As we know that an atom is represented by

_z^AX

here we know that

z = atomic number

A = atomic number + number of neutrons

now if the number of neutrons in an atom is different but having same number  atomic number then the combination of such group of atoms is known as isotopes.

So here we have

_z^{A_1}X, _z^{A_2}X

so above is the example of isotopes

How is velocity affected when balanced forces act on an object?
MrRissso [65]
When the forces acting on a body are balanced, their effect
\on the body's motion is the same as if no forces at all are
acting on it, and its velocity can't change.  It continues moving
in a straight line at constant speed (which may be zero).

An airplane accelerates from a velocity of 22 m/s to 40 m/s with an acceleration of 2 m/s2. How long does it
andrey2020 [161]

The time it takes the plane to change its velocity is 9s.

<h3>What is time?</h3>

Time can be defined the measured or measurable period during which an action, process, or condition exists or continues.

To calculate the time it takes the airplane to change its velocity, we use the formula below.

Formula:

  • t = (v-u)/a.......... Equation 1

Where:

  • a = Acceleration
  • v = Final velocity
  • u = Initial velocity
  • t = time

From the question,

  • v = 40 m/s
  • u = 22 m/s
  • a = 2 m/s²

Substitute these values into equation  1

  • t = (40-22)/2
  • t = 18/2
  • t = 9s

Hence, the time it takes the plane to change its velocity is 9s.
