The atomic number is the number of protons.  If the atomic number is 30, then the atom will have 30 protons.

Hi ;)
First of all, The number of protons is always equal to the number of electrons in a neutral atom.Since we have 30 protons and 30 electrons ,the positive charge on the proton is cancelled by the negative charge on the electron leaving a neutral atom.

Positive 30 and negative 30 equals 0.

Therefore , that atom would have 30 protons .

A car is being tested on a track. The driver approaches the test section at a speed of 28 m s−1. He then accelerates at a unifor
dedylja [7]

The uniform acceleration of the car is 4.485 m/s².

<h3>Acceleration of the car</h3>

The uniform acceleration of the car is calculated as follows;

v² = u² + 2as

a = (v² - u²)/2s

where;

  • v is final velocity = 41 m/s
  • u is initial velocity = 28 m/s
  • s is distance = 100 m
  • a is acceleration = ?

a = (41² - 28²)/(2 x 100)

a = 4.485 m/s²

Thus, the uniform acceleration of the car is 4.485 m/s².

If an electrical component with a resistance of 53 Q is connected to a 128-V source, how much current flows through the componen
natta225 [31]

Answer:

the current that flows through the component is 2.42 A

Explanation:

Given;

resistance of the electrical component, r = 53 Ω

the voltage of the source, V = 128 V

The current that flows through the component is calculated using Ohm's Law as demonstrated below;

V = IR\\\\I = \frac{V}{R} = \frac{128 \ V}{53 \ ohms} = 2.42 \ A

Therefore, the current that flows through the component is 2.42 A

Which of the following is an example of kinetic energy?
Lisa [10]
Kinetic Energy is the energy by virtue of object's motion. In first two options, no motion has occurred, so there would be no energy, and kinetic energy can also be seen in a swinging both which is in last option in the question.

In short, Your Answer would be Option D) A swing moving back and forth

Hope this helps!
