Answer: The number of electrons in an atom of zirconium are 40.

Explanation:

Electrons are one of the subatomic particles present in an atom.

Electrons in an atom is judged by the atomic number of the atom.

Atomic number = Number of protons = Number of electrons

Atomic number of Zirconium = 40

Number of electrons will be equal to 40

Electronic configuration of Zirconium (Z = 40): 1s^22s^22p^63s^23p^64s^23d^{10}4p^65d^24d^2

The correct answer is  1.4285714.

In physics, velocity is characterised as a vector measurement of the motion's direction and speed. To be more precise, the rate of change in an object's position relative to a frame of reference and time is another way to describe velocity. The definition of velocity simply states the rate of motion of an object in a specific direction. It determines how quickly or slowly something is going.

Velocity = distance/ time  

Thus time = distance/velocity

Here velocity = 350m/s

diatnce = 500 m

time = 500/350

time = 1.42857142857

t= 200m /350m/s  = 1.4285714

A car accelerates from rest to 90m/s in 3 seconds. What is the acceleration and how far did it travel?
Inessa [10]

Answer:

Explanation:

1.)acceleration= final velocity-initial velocity/time

90m/s-0m/s /3seconds

=30m/s^2

2.) distance= speed*time

90m/s*3seconds

=270m
