How dose an atom change if all of its electrons are removed

Anni [7]

Answer:

When all the electrons are removed from an atom, it becomes something as a positively charged particles also known as alpha particles.

Explanation: 

The bare nucleus which is positively charged help in scattering experiments as it has high penetrating powers. An atom is made up of electrons, protons and neutrons. We need huge energy to separate the electrons from their parent atom, still making it separated brings you a particle with a positive charge and only mass having high penetrating power.

A race car is accelerating at 5m/s and then speeds up to a final velocity of 12 m/s if the race car driver finished this let of

noname [10]

Answer:

the acceleration of the car is 1.167 m/s²

Explanation:

Given;

initial velocity of the race car, u = 5 m/s

final velocity of the race car, v = 12 m/s

time to finish the race, t = 6 s

The acceleration of the car is calculated as;

a = (v - u) / t

a = (12 - 5) / (6)

a = 1.167 m/s²

Therefore, the acceleration of the car is 1.167 m/s²

Richard is driving home to visit his parents. 150 mi of the trip are on the interstate highway where the speed limit is 65 mph .

Serggg [28]

Answer:

t = 25.5 min

Explanation:

To know how many minutes does Richard save, you first calculate the time that Richard takes with both velocities v1 = 65mph and v2 = 80mph.

$t_1=\frac{x}{v_1}=\frac{150mi}{65mph}=2.30h\\\\t_2=\frac{x}{v_2}=\frac{150mi}{80mph}=1.875h$

Next, you calculate the difference between both times t1 and t2:

$\Delta t=t_1-t_2=2.30h-1.875h=0.425h$

This is the time that Richard saves when he drives with a speed of 80mph. Finally, you convert the result to minutes:

$0.425h*\frac{60min}{1h}=25.5min=25\ min\ \ 30 s$

hence, Richard saves 25.5 min (25 min and 30 s) when he drives with a speed of 80mph

A moving particle encounters an external electric field that decreases its kinetic energy from 9970 eV to 6340 eV as the particl

marusya05 [52]

Answer:

q = -1.61x10⁻¹⁷ C

Explanation:

The charge of the particle can be found using the definition of the work done by electric force:

$W = -q\Delta V$ (1)

Where:

q: is the charge

ΔV: is the difference in electric potential

The work is also equal to:

$W = E_{p_{A}} - E_{p_{B}}$ (2)

Where:

$E_{p_{A}}$ and $E_{p_{B}}$ are the electric potential energy of the points A and B, respectively.

Now, by conservation of energy we have:

$K_{A} + E_{p_{A}} = K_{B} + E_{p_{B}}$ (3)

Where:

$K_{A}$ and $K_{B}$ are the kinetic energy of the points A and B, respectively.

Rearranging equation (3):

$K_{B} - K_{A} = E_{p_{A}} - E_{p_{B}}$

$K_{B} - K_{A} = W$

$K_{B} - K_{A} = -q\Delta V$

Solving the above equation for q:

$q = -\frac{K_{B} - K_{A}}{V_{B} - V_{A}} = -\frac{6340 eV - 9970 eV}{19.0 V - 55.0 V} = -100.83 e \cdot \frac{1.6 \cdot 10^{-19} C}{1 e} = -1.61 \cdot 10^{-17} C$

Therefore, the charge of the particle is -1.61x10⁻¹⁷ C.

I hope it helps you!
